libmad and other library issues

[Xephonic]

OK, i recently installed libmad and i can compile the library just fine by doing -lmad in my makefile

The issue is though when i try to add in mp3player.h and .c to play back mp3s in my program. For some reason i get undefined references to:
mad_frame_init
mad_synth_init
mad_stream_init
and mad_timer_zero

any ideas as to why?

Such things happen with other libraries ive installed as well. It reads them fine in the make file when i put them in library tags, but i keep getting all these undefined references. Am i installing the libs wrong?

i do a ./configure -prefix=/usr/local/pspdev/psp

then make
then make install

i dont get it :(

I also re-dled and ran toolchain.sh
