Telling SCons to Not Duplicate Source Files in the Build Directory
In most cases and with most tool sets,
SCons can place its target files in a build subdirectory
without
duplicating the source files
and everything will work just fine.
You can disable the default SCons behavior
by specifying duplicate=0
when you call the SConscript function:
SConscript('src/SConscript', build_dir='build', duplicate=0)
|
When this flag is specified,
SCons uses the build directory
like most people expect--that is,
the output files are placed in the build directory
while the source files stay in the source directory:
% ls src
SConscript
hello.c
% scons -Q
cc -c src/hello.c -o build/hello.o
cc -o build/hello build/hello.o
% ls build
hello
hello.o
