Has the file Hat.hs (in directory src/hat/lib) already been compiled? No; for some reason, after "make clean; make" the compile goes straight for hat.c and then for the above Haskell file. Rerunning "./configure" after deleting the targets directory fixed the maze of Makefiles, and ghc is building the Haskell source right now.

I think I understand what caused my problem. On Mac OS X, there is no /usr/bin/gcc; even though Apple's cc is gcc, it's called /usr/bin/cc. "CC=gcc" is hardcoded into targets/<target>/config.cache, but "configure" never checks for gcc; I guess that it assumes that if there's a working ghc there's a working gcc. Anyway, the first time I tried to build, the Haskell sources built fine but the build failed on "hat.c" because hmake couldn't find gcc. I edited config.cache by hand, ran "make clean", and restarted the build, but "make clean" didn't clean enough. Perhaps the "make clean" target should delete the targets directory?

[ By the way, ghc-5.04 has a bug (in 'show'ing named fields) which will prevent you from getting much further with building Hat in any case. You either need to wait for 5.04.1 to be released, or revert to 5.02.x for the moment. ] Thanks for the info; do you have an ETA on ghc-5.04.1? I'm unfamiliar with the ghc build process, but I understand that it involves some sort of bootstrapping like the build process of gcc. Will I be able to use my ghc 5.04 to build a new ghc 5.04.1 when it is released? Will it be compatible with gcc 3.1?
