Re: [Lib2geom-devel] Compilation problem

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello Jan,
   When I add "-shared" to the commandline that gives the error, it 
works. So now I have to figure out how to add that to the build...

Setting "PYTHON_ENABLE_MODULE__common_decl" and all that follow to OFF
and "PYTHON_MODULE__common_decl_BUILD_SHARED" and all that follow to ON, 
gives the following cmake error:

CMake Error at CMakeScripts/UseCython.cmake:247 (target_link_libraries):
   Cannot specify link libraries for target "_common_decl" which is not 
built
   by this project.
Call Stack (most recent call first):
   src/2geom/cython-bindings/CMakeLists.txt:55 (cython_add_module)

Thanks,
   Johan
