[CMake] How to specify -fpic ?

[David Aldrich]

Hi

Ok, by following the link to the wiki suggested by Michael Loose, I used:

target_link_libraries( myProj -Wl,-whole-archive Kernel -Wl,-no-whole-archive)

This has fixed my problem. The executable links and runs correctly.

My link command is now:

/usr/bin/c++   -O3 -DNDEBUG -Wall -m64  -Wl,--export-dynamic   -o myProj -Wl,-whole-archive Kernel/libKernel.a -Wl,-no-whole-archive -ldl -lpython2.4

I don't need portability so I think this is ok.

So my concern is now: am I being 'outlandish' ?  The dlopen'ed libraries do use functions in libKernel.a that is linked to the executable. Is this outlandish? Is there a better way?

Thanks for your help so far.
