In general, you need to compile everything that could be mapped at
arbitrary addresses (in the process's virtual address space) with the
-fPIC option to make it position independent (whatever that means for the
target platform). Programs are loaded at a fixed address (for i386 Linux,
this is somewhere around 0x80000000), so they needn't be compiled with
-fPIC, while shared libraries can be mapped to different addresses in
different processes and thus need -fPIC. Static libraries are collections
of .o files, also called relocatable objects, which are not position
independent, but contain the information how to move them to a specified
position ("relocate", which basically means adding the start address to
all pointers). Thus, they don't need -fPIC either.
