Compile your .c source files with the -fPIC option:

gcc -c -fPIC -o snafu.o snafu.c

This generates "Position Independent Code", ready for inclusion in a
shared object library using a command like:

gcc -shared -fPIC -o libfu.so snafu.o fubar.o

That syntax informs the linker to generate a shared library (without
-shared, it creates an executable image).
