I am trying to compile a shared library in Linux using a Makefile created with Cmake, but running make I obtain the following error:
Linking CXX shared library libcpp-lib.so
/usr/bin/ld: /home/davide/Desktop/boost_1_55_0/stage/lib/libboost_system.a(error_code.o): relocation R_X86_64_32 against .rodata.str1.1 can not be used when making a shared object; recompile with -fPIC
/home/davide/Desktop/boost_1_55_0/stage/lib/libboost_system.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[2]: *** [libcpp-lib.so] Error 1
make[1]: *** [CMakeFiles/cpp-lib.dir/all] Error 2
make: *** [all] Error 2
I provide the following command in the CMakeLists.txt in order to say that I want a shared (.so) library:
add_library(cpp-lib SHARED ${CPP_FILES})
What else do I need to specify in order to avoid the -fPIC error shown above?
Thanks a lot in advance
