Does anything in your poptools.c file actually refer to any symbols defined in the .a archive? If not, the linker will not need to search the archive and so will not include any of the archive contents in the output. You can use -Wl,--whole-archive libpop.a -Wl,--no-whole-archive to force the linker to include everything in the archive even if it isn't needed.
