Module contents

SCons platform selection.

Looks for modules that define a callable object that can modify a construction environment as appropriate for a given platform.

Note that we take a more simplistic view of “platform” than Python does. We’re looking for a single string that determines a set of tool-independent variables with which to initialize a construction environment. Consequently, we’ll examine both sys.platform and os.name (and anything else that might come in to play) in order to return some specification which is unique enough for our purposes.

Note that because this subsystem just selects a callable that can modify a construction environment, it’s possible for people to define their own “platform specification” in an arbitrary callable function. No one needs to use or tie in to this subsystem in order to roll their own platform definition.

SCons.Platform.DefaultToolList(platform, env)

Select a default tool list for the specified platform.

SCons.Platform.Platform(name='darwin')

Select a canned Platform specification.

class SCons.Platform.PlatformSpec(name, generate)

Bases: object

class SCons.Platform.TempFileMunge(cmd, cmdstr=None)

Bases: object

Convert long command lines to use a temporary file.

You can set an Environment variable (usually TEMPFILE) to this, then call it with a string argument, and it will perform temporary file substitution on it. This is used to circumvent limitations on the length of command lines. Example:

env["TEMPFILE"] = TempFileMunge
env["LINKCOM"] = "${TEMPFILE('$LINK $TARGET $SOURCES','$LINKCOMSTR')}"

By default, the name of the temporary file used begins with a prefix of ‘@’. This may be configured for other tool chains by setting the TEMPFILEPREFIX variable. Example:

env["TEMPFILEPREFIX"] = '-@'        # diab compiler
env["TEMPFILEPREFIX"] = '-via'      # arm tool chain
env["TEMPFILEPREFIX"] = ''          # (the empty string) PC Lint

You can configure the extension of the temporary file through the TEMPFILESUFFIX variable, which defaults to ‘.lnk’ (see comments in the code below). Example:

env["TEMPFILESUFFIX"] = '.lnt'   # PC Lint

Entries in the temporary file are separated by the value of the TEMPFILEARGJOIN variable, which defaults to an OS-appropriate value.

_print_cmd_str(target, source, env, cmdstr)

SCons.Platform.platform_default()

Return the platform string for our execution environment.

The returned value should map to one of the SCons/Platform/*.py files. Since scons is architecture independent, though, we don’t care about the machine architecture.

SCons.Platform.platform_module(name='darwin')

Return the imported module for the platform.

This looks for a module name that matches the specified argument. If the name is unspecified, we fetch the appropriate default for our execution environment.
