Hello,

I am trying to port Bionic Libc on to Genode. At time,I'm struck with the following error that comes when i compiled the library.

/home/paramesh/genode-14.08/mybuild/var/libcache/bionic_libc_x86/bionic_libc_x86.lib.a(syscall.o): relocation R_X86_64_PC32 against undefined symbol `__set_errno' can not be used when making a shared object; recompile with -fPIC

From the above compilation error, I understood that bionic_libc_x86.lib.a is not compiled with -fPIC flag enabled(which is needed for Position Independent code generation by compiler and that is what essentially needed in Shared LIb buiding(bionic_libstdc++.lib.so) that uses the above static library). So, i assigned -fPIC flag to compiler variable CC_OPT to resolve it, but it is not showing the effect.

So, can any one tell me how can I resolve it. Correct me if I'm wrong somewhere.

Thanks and Regards,
