This appendix contains descriptions of all of the construction variables that are potentially available "out of the box" in this version of SCons. Whether or not setting a construction variable in a construction environment will actually have an effect depends on whether any of the Tools and/or Builders that use the variable have been included in the construction environment.
In this appendix, we have
appended the initial $
(dollar sign) to the beginning of each
variable name when it appears in the text,
but left off the dollar sign
in the left-hand column
where the name appears for each entry.
This construction variable automatically introduces $_LDMODULEVERSIONFLAGS
if $LDMODULEVERSION is set. Othervise it evaluates to an empty string.
This construction variable automatically introduces $_SHLIBVERSIONFLAGS
if $SHLIBVERSION is set. Othervise it evaluates to an empty string.
A macro (by default a generator function) used to create the linker flags to specify
apple's linker's -compatibility_version flag.
The default generator uses $APPLELINK_COMPATIBILITY_VERSION
and $APPLELINK_NO_COMPATIBILITY_VERSION and $SHLIBVERSION
to determine the correct flag.
On Mac OS X this is used to set the linker flag: -compatibility_version
The value is specified as X[.Y[.Z]] where X is between 1 and 65535, Y can be omitted or between 1 and
255, Z can be omitted or between 1 and 255. This value will be derived from $SHLIBVERSION if
not
specified. The lowest digit will be dropped and replaced by a 0.
If the $APPLELINK_NO_COMPATIBILITY_VERSION is set then no -compatibility_version will be
output.
See MacOS's ld manpage for more details
A macro (by default a generator function) used to create the linker flags to specify apple's linker's
-current_version flag. The default generator uses $APPLELINK_CURRENT_VERSION and
$APPLELINK_NO_CURRENT_VERSION and $SHLIBVERSION to determine the correct flag.
On Mac OS X this is used to set the linker flag: -current_version
The value is specified as X[.Y[.Z]] where X is between 1 and 65535, Y can be omitted or between 1 and
255, Z can be omitted or between 1 and 255. This value will be set to $SHLIBVERSION if not
specified.
If the $APPLELINK_NO_CURRENT_VERSION is set then no -current_version will be
output.
See MacOS's ld manpage for more details
Set this to any True (1|True|non-empty string) value to disable adding -compatibility_version flag when generating versioned shared libraries.
This overrides $APPLELINK_COMPATIBILITY_VERSION.
Set this to any True (1|True|non-empty string) value to disable adding -current_version flag when generating versioned shared libraries.
This overrides $APPLELINK_CURRENT_VERSION.
The static library archiver.
Specifies the system architecture for which
the package is being built.
The default is the system architecture
of the machine on which SCons is running.
This is used to fill in the
Architecture:
field in an Ipkg
control file,
and the BuildArch: field
in the RPM .spec file,
as well as forming part of the name of a generated RPM package file.
The command line used to generate a static library from object files.
The string displayed when an object file
is generated from an assembly-language source file.
If this is not set, then $ARCOM (the command line) is displayed.
env = Environment(ARCOMSTR = "Archiving $TARGET")
General options passed to the static library archiver.
The assembler.
The command line used to generate an object file from an assembly-language source file.
The string displayed when an object file
is generated from an assembly-language source file.
If this is not set, then $ASCOM (the command line) is displayed.
env = Environment(ASCOMSTR = "Assembling $TARGET")
General options passed to the assembler.
The command line used to assemble an assembly-language
source file into an object file
after first running the file through the C preprocessor.
Any options specified
in the $ASFLAGS and $CPPFLAGS construction variables
are included on this command line.
The string displayed when an object file
is generated from an assembly-language source file
after first running the file through the C preprocessor.
If this is not set, then $ASPPCOM (the command line) is displayed.
env = Environment(ASPPCOMSTR = "Assembling $TARGET")
General options when an assembling an assembly-language
source file into an object file
after first running the file through the C preprocessor.
The default is to use the value of $ASFLAGS.
The bibliography generator for the TeX formatter and typesetter and the LaTeX structured formatter and typesetter.
The command line used to call the bibliography generator for the TeX formatter and typesetter and the LaTeX structured formatter and typesetter.
The string displayed when generating a bibliography
for TeX or LaTeX.
If this is not set, then $BIBTEXCOM (the command line) is displayed.
env = Environment(BIBTEXCOMSTR = "Generating bibliography $TARGET")
General options passed to the bibliography generator for the TeX formatter and typesetter and the LaTeX structured formatter and typesetter.
A dictionary mapping the names of the builders available through this environment to underlying Builder objects. Builders named Alias, CFile, CXXFile, DVI, Library, Object, PDF, PostScript, and Program are available by default. If you initialize this variable when an Environment is created:
env = Environment(BUILDERS = {'NewBuilder' : foo})
the default Builders will no longer be available. To use a new Builder object in addition to the default Builders, add your new Builder object like this:
env = Environment()
env.Append(BUILDERS = {'NewBuilder' : foo})
or this:
env = Environment() env['BUILDERS']['NewBuilder'] = foo
The C compiler.
The command line used to compile a C source file to a (static) object
file. Any options specified in the $CFLAGS, $CCFLAGS and
$CPPFLAGS construction variables are included on this command
line.
The string displayed when a C source file
is compiled to a (static) object file.
If this is not set, then $CCCOM (the command line) is displayed.
env = Environment(CCCOMSTR = "Compiling static object $TARGET")
General options that are passed to the C and C++ compilers.
Options added to the compiler command line
to support building with precompiled headers.
The default value expands expands to the appropriate
Microsoft Visual C++ command-line options
when the $PCH construction variable is set.
Options added to the compiler command line
to support storing debugging information in a
Microsoft Visual C++ PDB file.
The default value expands expands to appropriate
Microsoft Visual C++ command-line options
when the $PDB construction variable is set.
The Visual C++ compiler option that SCons uses by default
to generate PDB information is /Z7.
This works correctly with parallel (-j) builds
because it embeds the debug information in the intermediate object files,
as opposed to sharing a single PDB file between multiple object files.
This is also the only way to get debug information
embedded into a static library.
Using the /Zi instead may yield improved
link-time performance,
although parallel builds will no longer work.
You can generate PDB files with the /Zi
switch by overriding the default $CCPDBFLAGS variable as follows:
env['CCPDBFLAGS'] = ['${(PDB and "/Zi /Fd%s" % File(PDB)) or ""}']
An alternative would be to use the /Zi
to put the debugging information in a separate .pdb
file for each object file by overriding
the $CCPDBFLAGS variable as follows:
env['CCPDBFLAGS'] = '/Zi /Fd${TARGET}.pdb'
The version number of the C compiler. This may or may not be set, depending on the specific C compiler being used.
The suffix for C source files.
This is used by the internal CFile builder
when generating C files from Lex (.l) or YACC (.y) input files.
The default suffix, of course, is
.c
(lower case).
On case-insensitive systems (like Windows),
SCons also treats
.C
(upper case) files
as C files.
General options that are passed to the C compiler (C only; not C++).
A hook for modifying the file that controls the packaging build
(the .spec for RPM,
the control for Ipkg,
the .wxs for MSI).
If set, the function will be called
after the SCons template for the file has been written.
A reserved variable name that may not be set or used in a construction environment. (See "Variable Substitution," below.)
A reserved variable name that may not be set or used in a construction environment. (See "Variable Substitution," below.)
The name of a file containing the change log text
to be included in the package.
This is included as the
%changelog
section of the RPM
.spec file.
A function used to produce variables like $_CPPINCFLAGS. It takes
four or five
arguments: a prefix to concatenate onto each element, a list of
elements, a suffix to concatenate onto each element, an environment
for variable interpolation, and an optional function that will be
called to transform the list before concatenation.
env['_CPPINCFLAGS'] = '$( ${_concat(INCPREFIX, CPPPATH, INCSUFFIX, __env__, RDirs)} $)',
The name of the directory in which
Configure context test files are written.
The default is
.sconf_temp
in the top-level directory
containing the
SConstruct
file.
The name of the Configure context log file.
The default is
config.log
in the top-level directory
containing the
SConstruct
file.
An automatically-generated construction variable
containing the C preprocessor command-line options
to define values.
The value of $_CPPDEFFLAGS is created
by respectively prepending and appending
$CPPDEFPREFIX and $CPPDEFSUFFIX
to the beginning and end
of each definition in $CPPDEFINES.
A platform independent specification of C preprocessor definitions.
The definitions will be added to command lines
through the automatically-generated
$_CPPDEFFLAGS construction variable (see above),
which is constructed according to
the type of value of $CPPDEFINES:
If $CPPDEFINES is a string,
the values of the
$CPPDEFPREFIX and $CPPDEFSUFFIX
construction variables
will be respectively prepended and appended to the beginning and end
of each definition in $CPPDEFINES.
# Will add -Dxyz to POSIX compiler command lines, # and /Dxyz to Microsoft Visual C++ command lines. env = Environment(CPPDEFINES='xyz')
If $CPPDEFINES is a list,
the values of the
$CPPDEFPREFIX and $CPPDEFSUFFIX
construction variables
will be respectively prepended and appended to the beginning and end
of each element in the list.
If any element is a list or tuple,
then the first item is the name being
defined and the second item is its value:
# Will add -DB=2 -DA to POSIX compiler command lines,
# and /DB=2 /DA to Microsoft Visual C++ command lines.
env = Environment(CPPDEFINES=[('B', 2), 'A'])
If $CPPDEFINES is a dictionary,
the values of the
$CPPDEFPREFIX and $CPPDEFSUFFIX
construction variables
will be respectively prepended and appended to the beginning and end
of each item from the dictionary.
The key of each dictionary item
is a name being defined
to the dictionary item's corresponding value;
if the value is
None,
then the name is defined without an explicit value.
Note that the resulting flags are sorted by keyword
to ensure that the order of the options on the
command line is consistent each time
scons
is run.
# Will add -DA -DB=2 to POSIX compiler command lines,
# and /DA /DB=2 to Microsoft Visual C++ command lines.
env = Environment(CPPDEFINES={'B':2, 'A':None})
The prefix used to specify preprocessor definitions
on the C compiler command line.
This will be prepended to the beginning of each definition
in the $CPPDEFINES construction variable
when the $_CPPDEFFLAGS variable is automatically generated.
The suffix used to specify preprocessor definitions
on the C compiler command line.
This will be appended to the end of each definition
in the $CPPDEFINES construction variable
when the $_CPPDEFFLAGS variable is automatically generated.
User-specified C preprocessor options.
These will be included in any command that uses the C preprocessor,
including not just compilation of C and C++ source files
via the $CCCOM,
$SHCCCOM,
$CXXCOM and
$SHCXXCOM command lines,
but also the $FORTRANPPCOM,
$SHFORTRANPPCOM,
$F77PPCOM and
$SHF77PPCOM command lines
used to compile a Fortran source file,
and the $ASPPCOM command line
used to assemble an assembly language source file,
after first running each file through the C preprocessor.
Note that this variable does
not
contain
-I
(or similar) include search path options
that scons generates automatically from $CPPPATH.
See $_CPPINCFLAGS, below,
for the variable that expands to those options.
An automatically-generated construction variable
containing the C preprocessor command-line options
for specifying directories to be searched for include files.
The value of $_CPPINCFLAGS is created
by respectively prepending and appending $INCPREFIX and $INCSUFFIX
to the beginning and end
of each directory in $CPPPATH.
The list of directories that the C preprocessor will search for include
directories. The C/C++ implicit dependency scanner will search these
directories for include files. Don't explicitly put include directory
arguments in CCFLAGS or CXXFLAGS because the result will be non-portable
and the directories will not be searched by the dependency scanner. Note:
directory names in CPPPATH will be looked-up relative to the SConscript
directory when they are used in a command. To force
scons
to look-up a directory relative to the root of the source tree use #:
env = Environment(CPPPATH='#/include')
The directory look-up can also be forced using the
Dir()
function:
include = Dir('include')
env = Environment(CPPPATH=include)
The directory list will be added to command lines
through the automatically-generated
$_CPPINCFLAGS
construction variable,
which is constructed by
respectively prepending and appending the value of the
$INCPREFIX and $INCSUFFIX
construction variables
to the beginning and end
of each directory in $CPPPATH.
Any command lines you define that need
the CPPPATH directory list should
include $_CPPINCFLAGS:
env = Environment(CCCOM="my_compiler $_CPPINCFLAGS -c -o $TARGET $SOURCE")
The list of suffixes of files that will be scanned for C preprocessor implicit dependencies (#include lines). The default list is:
[".c", ".C", ".cxx", ".cpp", ".c++", ".cc", ".h", ".H", ".hxx", ".hpp", ".hh", ".F", ".fpp", ".FPP", ".m", ".mm", ".S", ".spp", ".SPP"]
The C++ compiler.
The command line used to compile a C++ source file to an object file.
Any options specified in the $CXXFLAGS and
$CPPFLAGS construction variables
are included on this command line.
The string displayed when a C++ source file
is compiled to a (static) object file.
If this is not set, then $CXXCOM (the command line) is displayed.
env = Environment(CXXCOMSTR = "Compiling static object $TARGET")
The suffix for C++ source files.
This is used by the internal CXXFile builder
when generating C++ files from Lex (.ll) or YACC (.yy) input files.
The default suffix is
.cc.
SCons also treats files with the suffixes
.cpp,
.cxx,
.c++,
and
.C++
as C++ files,
and files with
.mm
suffixes as Objective C++ files.
On case-sensitive systems (Linux, UNIX, and other POSIX-alikes),
SCons also treats
.C
(upper case) files
as C++ files.
General options that are passed to the C++ compiler.
By default, this includes the value of $CCFLAGS,
so that setting $CCFLAGS affects both C and C++ compilation.
If you want to add C++-specific flags,
you must set or override the value of $CXXFLAGS.
The version number of the C++ compiler. This may or may not be set, depending on the specific C++ compiler being used.

The TeX DVI file to PostScript converter.
General options passed to the TeX DVI file to PostScript converter.
A dictionary of environment variables
to use when invoking commands. When
$ENV is used in a command all list
values will be joined using the path separator and any other non-string
values will simply be coerced to a string.
Note that, by default,
scons
does
not
propagate the environment in force when you
execute
scons
to the commands used to build target files.
This is so that builds will be guaranteed
repeatable regardless of the environment
variables set at the time
scons
is invoked.
If you want to propagate your environment variables to the commands executed to build target files, you must do so explicitly:
import os env = Environment(ENV = os.environ)
Note that you can choose only to propagate
certain environment variables.
A common example is
the system
PATH
environment variable,
so that
scons
uses the same utilities
as the invoking shell (or other process):
import os
env = Environment(ENV = {'PATH' : os.environ['PATH']})
A function that will be called to escape shell special characters in command lines. The function should take one argument: the command line string to escape; and should return the escaped command line.

by appending $INCPREFIX and $INCSUFFIX
to the beginning and end
of each directory in $F03PATH.
The list of directories that the Fortran 03 compiler will search for include
directories. The implicit dependency scanner will search these
directories for include files. Don't explicitly put include directory
arguments in $F03FLAGS because the result will be non-portable
and the directories will not be searched by the dependency scanner. Note:
directory names in $F03PATH will be looked-up relative to the SConscript
directory when they are used in a command. To force
scons
to look-up a directory relative to the root of the source tree use #:
You only need to set $F03PATH if you need to define a specific
include path for Fortran 03 files.
You should normally set the $FORTRANPATH variable,
which specifies the include path
for the default Fortran compiler
for all Fortran versions.
env = Environment(F03PATH='#/include')
The directory look-up can also be forced using the
Dir()
function:
include = Dir('include')
env = Environment(F03PATH=include)
The directory list will be added to command lines
through the automatically-generated
$_F03INCFLAGS
construction variable,
which is constructed by
appending the values of the
$INCPREFIX and $INCSUFFIX
construction variables
to the beginning and end
of each directory in $F03PATH.

env = Environment(F03COM="my_compiler $_F03INCFLAGS -c -o $TARGET $SOURCE")
The command line used to compile a Fortran 03 source file to an object file
after first running the file through the C preprocessor.
Any options specified in the $F03FLAGS and $CPPFLAGS construction variables
are included on this command line.
You only need to set $F03PPCOM if you need to use a specific
C-preprocessor command line for Fortran 03 files.
You should normally set the $FORTRANPPCOM variable,
which specifies the default C-preprocessor command line
for all Fortran versions.
The string displayed when a Fortran 03 source file
is compiled to an object file
after first running the file through the C preprocessor.
If this is not set, then $F03PPCOM or $FORTRANPPCOM
(the command line) is displayed.

command line for Fortran 08 files.
You should normally set the $FORTRANCOM variable,
which specifies the default command line
for all Fortran versions.
The string displayed when a Fortran 08 source file
is compiled to an object file.
If this is not set, then $F08COM or $FORTRANCOM

which specifies the user-specified options
passed to the default Fortran compiler
for all Fortran versions.
An automatically-generated construction variable
containing the Fortran 08 compiler command-line options
for specifying directories to be searched for include files.
The value of $_F08INCFLAGS is created
by appending $INCPREFIX and $INCSUFFIX
to the beginning and end
of each directory in $F08PATH.
The list of directories that the Fortran 08 compiler will search for include
directories. The implicit dependency scanner will search these
directories for include files. Don't explicitly put include directory
arguments in $F08FLAGS because the result will be non-portable
and the directories will not be searched by the dependency scanner. Note:
directory names in $F08PATH will be looked-up relative to the SConscript
directory when they are used in a command. To force
scons
to look-up a directory relative to the root of the source tree use #:
You only need to set $F08PATH if you need to define a specific
include path for Fortran 08 files.
You should normally set the $FORTRANPATH variable,
which specifies the include path
for the default Fortran compiler
for all Fortran versions.

The directory look-up can also be forced using the
Dir()
function:
include = Dir('include')
env = Environment(F08PATH=include)
The directory list will be added to command lines
through the automatically-generated
$_F08INCFLAGS
construction variable,
which is constructed by
appending the values of the
$INCPREFIX and $INCSUFFIX
construction variables
to the beginning and end
of each directory in $F08PATH.
Any command lines you define that need
the F08PATH directory list should
include $_F08INCFLAGS:
env = Environment(F08COM="my_compiler $_F08INCFLAGS -c -o $TARGET $SOURCE")
The command line used to compile a Fortran 08 source file to an object file
after first running the file through the C preprocessor.

found by searching the
PATH
variable in the
ENV
environment used to execute the command.
If the construction variable
$IMPLICIT_COMMAND_DEPENDENCIES

.java
files.
The suffix for Java files;
.java
by default.
Specifies the Java version being used by the Java builder.
This is not currently used to select one
version of the Java compiler vs. another.
Instead, you should set this to specify the version of Java
supported by your javac compiler.
The default is 1.4.
This is sometimes necessary because
Java 1.5 changed the file names that are created
for nested anonymous inner classes,
which can cause a mismatch with the files
that SCons expects will be generated by the javac compiler.
Setting $JAVAVERSION to
1.5
(or 1.6, as appropriate)
can make SCons realize that a Java 1.5 or 1.6
build is actually up to date.

on other systems, this is
the same as $SHLIBPREFIX.
A macro that automatically generates loadable module's SONAME based on $TARGET,
$LDMODULEVERSION and $LDMODULESUFFIX. Used by LoadableModule builder
when the linker tool supports SONAME (e.g. gnulink).
The suffix used for loadable module file names. On Mac OS X, this is null; on other systems, this is the same as $SHLIBSUFFIX.

required, adds the version number to the library name, and creates the symlinks
that are needed. $LDMODULEVERSION versions should exist in the same
format as $SHLIBVERSION.
Extra flags added to $LDMODULECOM when building versioned
LoadableModule. These flags are only used when $LDMODULEVERSION is
set.
This macro automatically introduces extra flags to $LDMODULECOM when
building versioned LoadableModule (that is when
$LDMODULEVERSION is set). _LDMODULEVERSIONFLAGS
usually adds $SHLIBVERSIONFLAGS and some extra dynamically generated
options (such as -Wl,-soname=$_LDMODULESONAME). It is unused
by plain (unversioned) loadable modules.
The lexical analyzer generator.
The command line used to call the lexical analyzer generator to generate a source file.
The string displayed when generating a source file
using the lexical analyzer generator.
If this is not set, then $LEXCOM (the command line) is displayed.
env = Environment(LEXCOMSTR = "Lex'ing $TARGET from $SOURCES")
General options passed to the lexical analyzer generator.
Used only on windows environments to set a lex flag to prevent 'unistd.h' from being included. The default value is '--nounistd'.
An automatically-generated construction variable
containing the linker command-line options
for specifying directories to be searched for library.
The value of $_LIBDIRFLAGS is created
by respectively prepending and appending $LIBDIRPREFIX and $LIBDIRSUFFIX
to the beginning and end
of each directory in $LIBPATH.
The prefix used to specify a library directory on the linker command line.
This will be prepended to the beginning of each directory
in the $LIBPATH construction variable
when the $_LIBDIRFLAGS variable is automatically generated.
The suffix used to specify a library directory on the linker command line.
This will be appended to the end of each directory
in the $LIBPATH construction variable
when the $_LIBDIRFLAGS variable is automatically generated.
TODO
An automatically-generated construction variable
containing the linker command-line options
for specifying libraries to be linked with the resulting target.
The value of $_LIBFLAGS is created
by respectively prepending and appending $LIBLINKPREFIX and $LIBLINKSUFFIX
to the beginning and end
of each filename in $LIBS.
The prefix used to specify a library to link on the linker command line.
This will be prepended to the beginning of each library
in the $LIBS construction variable
when the $_LIBFLAGS variable is automatically generated.
The suffix used to specify a library to link on the linker command line.
This will be appended to the end of each library
in the $LIBS construction variable
when the $_LIBFLAGS variable is automatically generated.
The list of directories that will be searched for libraries.
The implicit dependency scanner will search these
directories for include files. Don't explicitly put include directory
arguments in $LINKFLAGS or $SHLINKFLAGS
because the result will be non-portable
and the directories will not be searched by the dependency scanner. Note:
directory names in LIBPATH will be looked-up relative to the SConscript
directory when they are used in a command. To force
scons
to look-up a directory relative to the root of the source tree use #:
env = Environment(LIBPATH='#/libs')
The directory look-up can also be forced using the
Dir()
function:
libs = Dir('libs')
env = Environment(LIBPATH=libs)
The directory list will be added to command lines
through the automatically-generated
$_LIBDIRFLAGS
construction variable,
which is constructed by
respectively prepending and appending the values of the
$LIBDIRPREFIX and $LIBDIRSUFFIX
construction variables
to the beginning and end
of each directory in $LIBPATH.
Any command lines you define that need
the LIBPATH directory list should
include $_LIBDIRFLAGS:
env = Environment(LINKCOM="my_linker $_LIBDIRFLAGS $_LIBFLAGS -o $TARGET $SOURCE")
The prefix used for (static) library file names. A default value is set for each platform (posix, win32, os2, etc.), but the value is overridden by individual tools (ar, mslib, sgiar, sunar, tlib, etc.) to reflect the names of the libraries they create.
A list of all legal prefixes for library file names.
When searching for library dependencies,
SCons will look for files with these prefixes,
the base library name,
and suffixes in the $LIBSUFFIXES list.
A list of one or more libraries that will be linked with any executable programs created by this environment.
The library list will be added to command lines
through the automatically-generated
$_LIBFLAGS
construction variable,
which is constructed by
respectively prepending and appending the values of the
$LIBLINKPREFIX and $LIBLINKSUFFIX
construction variables
to the beginning and end
of each filename in $LIBS.
Any command lines you define that need
the LIBS library list should
include $_LIBFLAGS:
env = Environment(LINKCOM="my_linker $_LIBDIRFLAGS $_LIBFLAGS -o $TARGET $SOURCE")
If you add a
File
object to the
$LIBS
list, the name of that file will be added to
$_LIBFLAGS,
and thus the link line, as is, without
$LIBLINKPREFIX
or
$LIBLINKSUFFIX.
For example:
env.Append(LIBS=File('/tmp/mylib.so'))
In all cases, scons will add dependencies from the executable program to all the libraries in this list.
The suffix used for (static) library file names. A default value is set for each platform (posix, win32, os2, etc.), but the value is overridden by individual tools (ar, mslib, sgiar, sunar, tlib, etc.) to reflect the names of the libraries they create.
A list of all legal suffixes for library file names.
When searching for library dependencies,
SCons will look for files with prefixes, in the $LIBPREFIXES list,
the base library name,
and these suffixes.
The abbreviated name, preferably the SPDX code, of the license under which this project is released (GPL-3.0, LGPL-2.1, BSD-2-Clause etc.). See http://www.opensource.org/licenses/alphabetical for a list of license names and SPDX codes.
The separator used by the Substfile and Textfile builders.
This value is used between sources when constructing the target.
It defaults to the current system line separator.
The $LINGUAS_FILE defines file(s) containing list of additional linguas
to be processed by POInit, POUpdate or MOFiles
builders. It also affects Translate builder. If the variable contains
a string, it defines name of the list file. The $LINGUAS_FILE may be a
list of file names as well. If $LINGUAS_FILE is set to
True (or non-zero numeric value), the list will be read from
default file named
LINGUAS.
The linker.
The command line used to link object files into an executable.
The string displayed when object files
are linked into an executable.
If this is not set, then $LINKCOM (the command line) is displayed.
env = Environment(LINKCOMSTR = "Linking $TARGET")
General user options passed to the linker.
Note that this variable should
not
contain
-l
(or similar) options for linking with the libraries listed in $LIBS,
nor
-L
(or similar) library search path options
that scons generates automatically from $LIBPATH.
See
$_LIBFLAGS
above,
for the variable that expands to library-link options,
and
$_LIBDIRFLAGS
above,
for the variable that expands to library search path options.
The M4 macro preprocessor.
The command line used to pass files through the M4 macro preprocessor.

If this is not set, then $MAKEINDEXCOM (the command line) is displayed.
General options passed to the makeindex generator for the TeX formatter and typesetter and the LaTeX structured formatter and typesetter.
The maximum number of characters allowed on an external command line. On Win32 systems, link lines longer than this many characters are linked via a temporary file name.
The Microsoft IDL compiler.
The command line used to pass files to the Microsoft IDL compiler.
The string displayed when
the Microsoft IDL copmiler is called.
If this is not set, then $MIDLCOM (the command line) is displayed.

The directory containing the Microsoft SDK (either Platform SDK or Windows SDK) to be used for compilation.
The version string of the Microsoft SDK
(either Platform SDK or Windows SDK)
to be used for compilation.
Supported versions include
6.1,
6.0A,
6.0,
2003R2
and
2003R1.
When set to any true value,
specifies that SCons should batch
compilation of object files
when calling the Microsoft Visual C/C++ compiler.
All compilations of source files from the same source directory
that generate target files in a same output directory
and were configured in SCons using the same construction environment
will be built in a single call to the compiler.
Only source files that have changed since their
object files were built will be passed to each compiler invocation
(via the $CHANGED_SOURCES construction variable).
Any compilations where the object (target) file base name
(minus the .obj)
does not match the source file base name
will be compiled separately.
Use a batch script to set up Microsoft Visual Studio compiler
$MSVC_USE_SCRIPT overrides $MSVC_VERSION and $TARGET_ARCH.
If set to the name of a Visual Studio .bat file (e.g. vcvars.bat),
SCons will run that bat file and extract the relevant variables from
the result (typically %INCLUDE%, %LIB%, and %PATH%). Setting
MSVC_USE_SCRIPT to None bypasses the Visual Studio autodetection
entirely; use this if you are running SCons in a Visual Studio cmd
window and importing the shell's environment variables.
Build libraries for a Universal Windows Platform (UWP) Application.
If $MSVC_UWP_APP is set, the Visual Studio environment will be set up to point
to the Windows Store compatible libraries and Visual Studio runtimes. In doing so,
any libraries that are built will be able to be used in a UWP App and published
to the Windows Store.
This flag will only have an effect with Visual Studio 2015+.
This variable must be passed as an argument to the Environment()
constructor; setting it later has no effect.
Valid values are '1' or '0'
Sets the preferred version of Microsoft Visual C/C++ to use.
If $MSVC_VERSION is not set, SCons will (by default) select the
latest version of Visual C/C++ installed on your system. If the
specified version isn't installed, tool initialization will fail.
This variable must be passed as an argument to the Environment()
constructor; setting it later has no effect.
Valid values for Windows are
14.1,
14.0,
14.0Exp,
12.0,
12.0Exp,
11.0,
11.0Exp,
10.0,
10.0Exp,
9.0,
9.0Exp,
8.0,
8.0Exp,
7.1,
7.0,
and 6.0.
Versions ending in Exp refer to "Express" or
"Express for Desktop" editions.
When the Microsoft Visual Studio tools are initialized, they set up this dictionary with the following keys:
the version of MSVS being used (can be set via
$MSVS_VERSION)
the available versions of MSVS installed
installed directory of Visual C++
installed directory of Visual Studio
installed directory of the .NET framework
list of installed versions of the .NET framework, sorted latest to oldest.
latest installed version of the .NET framework
installed location of the .NET SDK.
installed location of the Platform SDK.
dictionary of installed Platform SDK modules, where the dictionary keys are keywords for the various modules, and the values are 2-tuples where the first is the release date, and the second is the version number.
If a value is not set, it was not available in the registry.
Sets the architecture for which the generated project(s) should build.
The default value is x86.
amd64 is also supported by SCons for
most Visual Studio versions. Since Visual Studio 2015
arm is supported, and since Visual Studio
2017 arm64 is supported.
Trying to set $MSVS_ARCH
to an architecture that's not supported for a given Visual
Studio version will generate an error.
The string placed in a generated
Microsoft Visual Studio project file as the value of the
ProjectGUID attribute. There is no default
value. If not
defined, a new GUID is generated.
The path name placed in a generated
Microsoft Visual Studio project file as the value of the
SccAuxPath attribute if the
MSVS_SCC_PROVIDER construction variable is
also set. There is
no default value.
The root path of projects in your SCC workspace, i.e the
path under which all project and solution files will be
generated. It is used as a reference path from which the
relative paths of the generated Microsoft Visual Studio project
and solution files are computed. The relative project file path
is placed as the value of the SccLocalPath
attribute of the project file and as the values of the
SccProjectFilePathRelativizedFromConnection[i]
(where [i] ranges from 0 to the number of projects in the solution)
attributes of the GlobalSection(SourceCodeControl)
section of the Microsoft Visual Studio solution file. Similarly
the relative solution file path is placed as the values of the
SccLocalPath[i] (where [i] ranges from 0
to the number of projects in the solution) attributes of the
GlobalSection(SourceCodeControl) section of
the Microsoft Visual Studio solution file. This is used only if
the MSVS_SCC_PROVIDER construction variable is
also set. The default value is the current working directory.
The project name placed in a generated Microsoft
Visual Studio project file as the value of the
SccProjectName attribute if the
MSVS_SCC_PROVIDER construction variable
is also set. In this case the string is also placed in
the SccProjectName0 attribute of the
GlobalSection(SourceCodeControl) section
of the Microsoft Visual Studio solution file. There is no
default value.
The string placed in a generated Microsoft
Visual Studio project file as the value of the
SccProvider attribute. The string is
also placed in the SccProvider0 attribute
of the GlobalSection(SourceCodeControl)
section of the Microsoft Visual Studio solution file. There
is no default value.
Sets the preferred version of Microsoft Visual Studio to use.
If $MSVS_VERSION is not set, SCons will (by default)
select the latest version of Visual Studio installed on your
system. So, if you have version 6 and version 7 (MSVS .NET)
installed, it will prefer version 7. You can override this by
specifying the MSVS_VERSION variable in the
Environment initialization, setting it to the appropriate
version ('6.0' or '7.0', for example). If the specified
version isn't installed, tool initialization will fail.
This is obsolete: use $MSVC_VERSION instead. If
$MSVS_VERSION is set and $MSVC_VERSION is
not, $MSVC_VERSION will be set automatically to
$MSVS_VERSION. If both are set to different values,
scons will raise an error.
The build command line placed in a generated Microsoft Visual Studio project file. The default is to have Visual Studio invoke SCons with any specified build targets.
The clean command line placed in a generated Microsoft Visual Studio project file. The default is to have Visual Studio invoke SCons with the -c option to remove any specified targets.
The encoding string placed in a generated Microsoft
Visual Studio project file. The default is encoding
Windows-1252.
The action used to generate Microsoft Visual Studio project files.
The suffix used for Microsoft Visual Studio project (DSP)
files. The default value is .vcproj
when using Visual Studio version 7.x (.NET) or later version,
and .dsp when using earlier versions of
Visual Studio.
The rebuild command line placed in a generated Microsoft Visual Studio project file. The default is to have Visual Studio invoke SCons with any specified rebuild targets.
The SCons used in generated Microsoft Visual Studio project files. The default is the version of SCons being used to generate the project file.
The default SCons command used in generated Microsoft Visual Studio project files.
The sconscript file (that is, SConstruct or SConscript
file) that will be invoked by Visual Studio project files
(through the $MSVSSCONSCOM variable). The default
is the same sconscript file that contains the call to
MSVSProject to build the project file.
The SCons flags used in generated Microsoft Visual Studio project files.
The action used to generate Microsoft Visual Studio solution files.
The suffix used for Microsoft Visual Studio solution (DSW)
files. The default value is .sln
when using Visual Studio version 7.x (.NET), and
.dsw when using earlier versions of
Visual Studio.
The program used on Windows systems to embed manifests into DLLs and EXEs.
See also $WINDOWS_EMBED_MANIFEST.
The Windows command line used to embed manifests into executables.
See also $MTSHLIBCOM.
Flags passed to the $MT manifest embedding program (Windows only).
The Windows command line used to embed manifests into shared libraries (DLLs).
See also $MTEXECOM.
The version number of the MetroWerks CodeWarrior C compiler to be used.
A list of installed versions of the MetroWerks CodeWarrior C compiler on this system.
Specfies the name of the project to package.
When set to non-zero,
suppresses creation of a corresponding Windows static import lib by the
SharedLibrary
builder when used with
MinGW, Microsoft Visual Studio or Metrowerks.
This also suppresses creation
of an export (.exp) file
when using Microsoft Visual Studio.
The prefix used for (static) object file names.
The suffix used for (static) object file names.
Specifies the directory where all files in resulting archive will be placed if applicable. The default value is "$NAME-$VERSION".
Selects the package type to build. Currently these are available:
* msi - Microsoft Installer * rpm - Redhat Package Manger * ipkg - Itsy Package Management System * tarbz2 - compressed tar * targz - compressed tar * zip - zip file * src_tarbz2 - compressed tar source * src_targz - compressed tar source * src_zip - zip file source
This may be overridden with the "package_type" command line option.
The version of the package (not the underlying project). This is currently only used by the rpm packager and should reflect changes in the packaging, not the underlying project code itself.
The Microsoft Visual C++ precompiled header that will be used when compiling object files. This variable is ignored by tools other than Microsoft Visual C++. When this variable is defined SCons will add options to the compiler command line to cause it to use the precompiled header, and will also set up the dependencies for the PCH file. Example:
env['PCH'] = 'StdAfx.pch'
The command line used by the
PCH
builder to generated a precompiled header.
The string displayed when generating a precompiled header.
If this is not set, then $PCHCOM (the command line) is displayed.
A construction variable that, when expanded,
adds the /yD flag to the command line
only if the $PDB construction variable is set.
This variable specifies how much of a source file is precompiled. This variable is ignored by tools other than Microsoft Visual C++, or when the PCH variable is not being used. When this variable is define it must be a string that is the name of the header that is included at the end of the precompiled portion of the source files, or the empty string if the "#pragma hrdstop" construct is being used:
env['PCHSTOP'] = 'StdAfx.h'
The Microsoft Visual C++ PDB file that will store debugging information for object files, shared libraries, and programs. This variable is ignored by tools other than Microsoft Visual C++. When this variable is defined SCons will add options to the compiler and linker command line to cause them to generate external debugging information, and will also set up the dependencies for the PDB file. Example:
env['PDB'] = 'hello.pdb'
The Visual C++ compiler switch that SCons uses by default
to generate PDB information is /Z7.
This works correctly with parallel (-j) builds
because it embeds the debug information in the intermediate object files,
as opposed to sharing a single PDB file between multiple object files.
This is also the only way to get debug information
embedded into a static library.
Using the /Zi instead may yield improved
link-time performance,
although parallel builds will no longer work.
You can generate PDB files with the /Zi
switch by overriding the default $CCPDBFLAGS variable;
see the entry for that variable for specific examples.
A deprecated synonym for $DVIPDFCOM.
The pdflatex utility.
The command line used to call the pdflatex utility.
The string displayed when calling the pdflatex utility.
If this is not set, then $PDFLATEXCOM (the command line) is displayed.

General options passed to the pdflatex utility.
The prefix used for PDF file names.
The suffix used for PDF file names.
The pdftex utility.
The command line used to call the pdftex utility.
The string displayed when calling the pdftex utility.
If this is not set, then $PDFTEXCOM (the command line) is displayed.
env = Environment(PDFTEXCOMSTR = "Building $TARGET from TeX input $SOURCES")
General options passed to the pdftex utility.
On Solaris systems,
the package-checking program that will
be used (along with $PKGINFO)
to look for installed versions of
the Sun PRO C++ compiler.
The default is
/usr/sbin/pgkchk.
On Solaris systems,
the package information program that will
be used (along with $PKGCHK)
to look for installed versions of
the Sun PRO C++ compiler.
The default is
pkginfo.
The name of the platform used to create the Environment. If no platform is
specified when the Environment is created,
scons
autodetects the platform.
env = Environment(tools = [])
if env['PLATFORM'] == 'cygwin':
Tool('mingw')(env)
else:
Tool('msvc')(env)
The $POAUTOINIT variable, if set to True (on non-zero
numeric value), let the msginit tool to automatically initialize
missing PO files with
msginit(1). This applies to both,
POInit and POUpdate builders (and others that use any of
them).
Common alias for all PO files created with POInit
builder (default: 'po-create').
See msginit tool and POInit builder.
Suffix used for PO files (default: '.po')
See msginit tool and POInit builder.
The $POTDOMAIN defines default domain, used to generate
POT filename as $POTDOMAIN.potPOT file name is provided by the user. This applies to
POTUpdate, POInit and POUpdate builders (and
builders, that use them, e.g. Translate). Normally (if $POTDOMAIN is
not defined), the builders use messages.pot as default
POT file name.
Suffix used for PO Template files (default: '.pot').
See xgettext tool and POTUpdate builder.
Name of the common phony target for all PO Templates created with
POUpdate (default: 'pot-update').
See xgettext tool and POTUpdate builder.
Common alias for all PO files being defined with
POUpdate builder (default: 'po-update').
See msgmerge tool and POUpdate builder.
A Python function used to print the command lines as they are executed
(assuming command printing is not disabled by the
-q
or
-s
options or their equivalents).
The function should take four arguments:
s,
the command being executed (a string),
target,
the target being built (file node, list, or string name(s)),
source,
the source(s) used (file node, list, or string name(s)), and
env,
the environment being used.
The function must do the printing itself. The default implementation, used if this variable is not set or is None, is:
def print_cmd_line(s, target, source, env): sys.stdout.write(s + "\n")
Here's an example of a more interesting function:
def print_cmd_line(s, target, source, env):
sys.stdout.write("Building %s -> %s...\n" %
(' and '.join([str(x) for x in source]),
' and '.join([str(x) for x in target])))
env=Environment(PRINT_CMD_LINE_FUNC=print_cmd_line)
env.Program('foo', 'foo.c')
This just prints "Building targetname from sourcename..." instead
of the actual commands.
Such a function could also log the actual commands to a log file,
for example.
TODO
The prefix used for executable file names.
The suffix used for executable file names.
The command line used to convert TeX DVI files into a PostScript file.
The string displayed when a TeX DVI file

Default value is ''. Prefix for uic generated header files.
Default value is '.h'. Suffix for uic generated header files.
Default value is ''. These flags are passed to uic, when creating a cxx file from a .ui file.
Default value is 'uic_'. Prefix for uic generated implementation files.
Default value is '$CXXFILESUFFIX'. Suffix for uic generated implementation
files.
Default value is '.ui'. Suffix of designer input files.
The qt tool tries to take this from os.environ.
It also initializes all QT_*
construction variables listed below.
(Note that all paths are constructed
with python's os.path.join() method,
but are listed here with the '/' separator
for easier reading.)
In addition, the construction environment
variables $CPPPATH,
$LIBPATH and
$LIBS may be modified
and the variables
$PROGEMITTER, $SHLIBEMITTER and $LIBEMITTER
are modified. Because the build-performance is affected when using this tool,
you have to explicitly specify it at Environment creation:
Environment(tools=['default','qt'])
The qt tool supports the following operations:
Automatic moc file generation from header files.
You do not have to specify moc files explicitly, the tool does it for you.
However, there are a few preconditions to do so: Your header file must have
the same filebase as your implementation file and must stay in the same
directory. It must have one of the suffixes .h, .hpp, .H, .hxx, .hh. You
can turn off automatic moc file generation by setting QT_AUTOSCAN to 0.
See also the corresponding
Moc()
builder method.
Automatic moc file generation from cxx files.
As stated in the qt documentation, include the moc file at the end of
the cxx file. Note that you have to include the file, which is generated
by the transformation ${QT_MOCCXXPREFIX}<basename>${QT_MOCCXXSUFFIX}, by default
<basename>.moc. A warning is generated after building the moc file, if you
do not include the correct file. If you are using VariantDir, you may
need to specify duplicate=1. You can turn off automatic moc file generation
by setting QT_AUTOSCAN to 0. See also the corresponding
Moc
builder method.
Automatic handling of .ui files.
The implementation files generated from .ui files are handled much the same
as yacc or lex files. Each .ui file given as a source of Program, Library or
SharedLibrary will generate three files, the declaration file, the
implementation file and a moc file. Because there are also generated headers,
you may need to specify duplicate=1 in calls to VariantDir.
See also the corresponding
Uic
builder method.
The archive indexer.
The command line used to index a static library archive.
The string displayed when a static library archive is indexed.
If this is not set, then $RANLIBCOM (the command line) is displayed.

TODO
Instructs the SharedLibrary builder to not create symlinks for versioned
shared libraries.
The prefix used for shared library file names.
A macro that automatically generates shared library's SONAME based on $TARGET,
$SHLIBVERSION and $SHLIBSUFFIX. Used by SharedLibrary builder when
the linker tool supports SONAME (e.g. gnulink).
The suffix used for shared library file names.
When this construction variable is defined, a versioned shared library
is created by SharedLibrary builder. This activates the
$_SHLIBVERSIONFLAGS and thus modifies the $SHLINKCOM as
required, adds the version number to the library name, and creates the symlinks
that are needed. $SHLIBVERSION versions should exist as alpha-numeric,
decimal-delimited values as defined by the regular expression "\w+[\.\w+]*".
Example $SHLIBVERSION values include '1', '1.2.3', and '1.2.gitaa412c8b'.
This macro automatically introduces extra flags to $SHLINKCOM when
building versioned SharedLibrary (that is when $SHLIBVERSION
is set). _SHLIBVERSIONFLAGS usually adds $SHLIBVERSIONFLAGS
and some extra dynamically generated options (such as
-Wl,-soname=$_SHLIBSONAME. It is unused by "plain"
(unversioned) shared libraries.

and the directories will not be searched by the dependency scanner.
Note: directory names in SWIGPATH will be looked-up relative to the SConscript
directory when they are used in a command.
To force
scons
to look-up a directory relative to the root of the source tree use #:
env = Environment(SWIGPATH='#/include')

Sets the target architecture for Visual Studio compiler (i.e. the arch
of the binaries generated by the compiler). If not set, default to
$HOST_ARCH, or, if that is unset, to the architecture of the
running machine's OS (note that the python build or architecture has no
effect).
This variable must be passed as an argument to the Environment()
constructor; setting it later has no effect.
This is currently only used on Windows, but in the future it will be
used on other OSes as well.

This is useful if some specific RPM feature not otherwise
anticipated by SCons needs to be turned on or off.
Note if this variable is omitted, SCons will by
default supply the value
'%global debug_package %{nil}'
to disable debug package generation.
To enable debug package generation, include this
variable set either to None, or to a custom
list that does not include the default line.
Added in version 3.1.

Path to xgettext(1) program (found via
Detect()).
See xgettext tool and POTUpdate builder.
Complete xgettext command line.
See xgettext tool and POTUpdate builder.
A string that is shown when xgettext(1) command is invoked
(default: '', which means "print $XGETTEXTCOM").
See xgettext tool and POTUpdate builder.
Internal "macro". Generates xgettext domain name
form source and target (default: '${TARGET.filebase}').
Additional flags to xgettext(1).
See xgettext tool and POTUpdate builder.
Name of file containing list of xgettext(1)'s source
files. Autotools' users know this as POTFILES.in so they
will in most cases set XGETTEXTFROM="POTFILES.in" here.
The $XGETTEXTFROM files have same syntax and semantics as the well known
GNU POTFILES.in.
See xgettext tool and POTUpdate builder.
Internal "macro". Genrates list of -D<dir> flags
from the $XGETTEXTPATH list.
This flag is used to add single $XGETTEXTFROM file to
xgettext(1)'s commandline (default:
'-f').
(default: '')
List of directories, there xgettext(1) will look for
source files (default: []).
This variable works only together with $XGETTEXTFROM
Internal "macro". Generates list of -f<file> flags
from $XGETTEXTFROM.
This flag is used to add single search path to
xgettext(1)'s commandline (default:
'-D').
(default: '')
The parser generator.
The command line used to call the parser generator to generate a source file.
The string displayed when generating a source file
using the parser generator.
If this is not set, then $YACCCOM (the command line) is displayed.
env = Environment(YACCCOMSTR = "Yacc'ing $TARGET from $SOURCES")
General options passed to the parser generator.
If $YACCFLAGS contains a -d option,
SCons assumes that the call will also create a .h file
(if the yacc source file ends in a .y suffix)
or a .hpp file
(if the yacc source file ends in a .yy suffix)
The suffix of the C
header file generated by the parser generator
when the
-d
option is used.
Note that setting this variable does not cause
the parser generator to generate a header
file with the specified suffix,
it exists to allow you to specify
what suffix the parser generator will use of its own accord.
The default value is
.h.
The suffix of the C++
header file generated by the parser generator
when the
-d
option is used.
Note that setting this variable does not cause
the parser generator to generate a header
file with the specified suffix,
it exists to allow you to specify
what suffix the parser generator will use of its own accord.
The default value is
.hpp,
except on Mac OS X,
where the default is
${TARGET.suffix}.h.
because the default bison parser generator just
appends .h
to the name of the generated C++ file.
The suffix of the file
containing the VCG grammar automaton definition
when the
--graph=
option is used.
Note that setting this variable does not cause
the parser generator to generate a VCG
file with the specified suffix,
it exists to allow you to specify
what suffix the parser generator will use of its own accord.
The default value is
.vcg.
The zip compression and file packaging utility.
The command line used to call the zip utility, or the internal Python function used to create a zip archive.
The
compression
flag
from the Python
zipfile
module used by the internal Python function
to control whether the zip archive
is compressed or not.
The default value is
zipfile.ZIP_DEFLATED,
which creates a compressed zip archive.
This value has no effect if the
zipfile
module is unavailable.
The string displayed when archiving files
using the zip utility.
If this is not set, then $ZIPCOM
(the command line or internal Python function) is displayed.
env = Environment(ZIPCOMSTR = "Zipping $TARGET")
General options passed to the zip utility.
An optional zip root directory (default empty). The filenames stored in the zip file will be relative to this directory, if given. Otherwise the filenames are relative to the current directory of the command. For instance:
env = Environment()
env.Zip('foo.zip', 'subdir1/subdir2/file1', ZIPROOT='subdir1')
will produce a zip file foo.zip
containing a file with the name
subdir2/file1 rather than
subdir1/subdir2/file1.
The suffix used for zip file names.
