(currently) glibc emulates aio by using threads. thus, you may have to
link to -lpthread.

it would help greatly if you included the actual undefined symbols.

as matthew mentioned, the glibc info docs contain lots of useful
stuff. you should probably read further there.


(if you really want, you could run 2.4 and i think there's some
preliminary patches around to implement kernel aio)
