Hi,
i'm trying to build a static version of dolfin. I set BUILD_SHARED_LIBS to off, but compilation fails with
Building CXX object dolfin/swig/modules/la/CMakeFiles/_la.dir/modulePYTHON_wrap.cxx.o
Linking CXX shared module _la.so
/usr/bin/ld: /lrz/sys/tools/python/2.7.4/lib/libpython2.7.a(abstract.o): relocation R_X86_64_32S against `_Py_NotImplementedStruct' can not be used when making a shared object; recompile with -fPIC
/lrz/sys/tools/python/2.7.4/lib/libpython2.7.a: could not read symbols: Bad value
so, while creating the libdolfin.a works, an option like --shared-libgcc is still passed to the compiler when building the swig modules. Now, is this a bug, do i have to set another option to off, or does exist a workaround?
I greped for shared-libgcc to find where this option is set, but it only returns entries from the CMakeOutput.log. I searched the dolfin/swig/modules/*/CMakeLists.txt for a possibility to change this, but still no luck.
I actually could recompile the needed libraries with -fpic as the message suggests, and this worked already for similar errors, but: First, recompiling every library is timeconsuming, as i only can login to the cluster with ssh, and no library is placed i s placed in an usual location, als "/lrz/sys/tools/python/2.7.4/lib/libpython2.7.a" already suggests. Second, there are libraries i can't recompile (like python) due to me not having root access, third, this would still build shared libs from the swig modules, and final reason is -fpic can make applications significantly slower.
