Hi, I installed OpenAL and ALUT bindings downloaded from http://hackage.haskell.org/packages/archive/pkg-list.html and tried compilation of "HelloWorld.hs" example which I got from http://darcs.haskell.org/packages/ALUT/

But it returns errors as follow and I can not get an '.exe' file. Though there are clearly "link errors", I can not understand why it happens. By option "-package ALUT", libalut.a (which made by pexports and dlltool because I do not know original "alut.lib" can be used by mingw) and other necessary libraries are automatically linked, I think. What is "@8" of "alutInit@8"?

How can I avoid these errors? My environment is Windows XP SP2, GHC6.6, MinGW/MSYS (so some of mingw tools are duplicated. one is GHC's, the other is MinGW's)

@8 is name mangling, used by the (Windows-specific) calling convention for these symbols. Probably, a convention declaration was omitted in ALUT, and not noticed because it would only affect windows. Report a bug (http://hackage.haskell.org/trac/ghc/newticket?type=bug). Disclaimer: I haven't used windows in four years.
