[Scons-users] Include path problem

[Hartmut.Brandt at dlr.de]

Hi,

I fail to understand the handling of CPPPATH with regard to variant directories. I have a complex project with several libraries in the source:

SConstruct
a/b/c/libabc
a/b/c/libabc/SConscript
d/libd
d/libd/SConscript

Now I need to include header files from libabc when compiling libd using "c/libabc/x.h". And I'm using variant_dir.

I cannot get libd's SConscript to put me a corresponding -I<absolute-source-path>/a/b into the compiler command line. Whatever I try I just get -Ia/b. That does not work, of course since the compiler is executed in the build directory.

For the library itself this works just fine: I export the library target from libd/SConscript, import it in libabc/SConscript and give it to the shared library builder. Scons manages the path. Couldn't that be as simple for the include path?

Thanks,
harti
