VariantDir With an SConscript File
Even when using the VariantDir function,
it's much more natural to use it with
a subsidiary SConscript file.
For example, if the
src/SConscript
looks like this:
env = Environment()
env.Program('hello.c')
Then our SConstruct file could look like:
VariantDir('build', 'src')
SConscript('build/SConscript')
Yielding the following output:
% ls src
SConscript hello.c
% scons -Q
cc -o build/hello.o -c build/hello.c
cc -o build/hello build/hello.o
% ls build
SConscript hello hello.c hello.o
Notice that this is completely equivalent to the use of SConscript that we learned about in the previous section.
