shure, "caibd" is the called C procedure from AIBD. well then, i type

...

ghc Main.o AIBD.o HAIBDUtil.o -o HAIBD.exe

then everything is fine, and i get my executable. Now i wanted to profile, and added the options "-prof --auto-all" to the first ghc command. When trying to link, i get lot's of undefined references:

...

ghc Main.o AIBD.o HAIBDUtil.o -o HAIBD.exe

AIBD.o(.text+0x425):ghc1364.hc: undefined reference to `CC_LIST' AIBD.o(.text+0x430):ghc1364.hc: undefined reference to `CC_LIST' AIBD.o(.text+0x439):ghc1364.hc: undefined reference to `CC_ID' AIBD.o(.text+0x444):ghc1364.hc: undefined reference to `CC_ID' (...)

You forgot to add -prof to the link line, too. Cheers, Simon
