It s obvious your linker did not find any proper lib to link with your object codes. It maybe caused by wrong name in -l option. You should be certain of exist such file named, 'libmp3Decoder.s' or 'libmp3Decoder.a' in your lib path.
Sometimes you cant find it in these certain pathes, so you must include exact path contain that lib.
