Has anyone had any luck building a windows version of GHC under cygwin? I followed the instruction on the building guide to build it under MinGW/msys, which works, but when I try to build it under cygwin instead of msys I get this: cabal-bin.exe: Cannot find the program 'ghc' at '/cygdrive/c/dev/haskell/ghc/ghc-6.10.1/bin/ghc' or on the path make[1]: *** [bootstrapping.conf] Error 1 make[1]: Leaving directory `/cygdrive/c/dev/haskell/ghc/ghc-6.10.1-src/libraries' make: *** [stage1] Error 2 Fairly early in the build process. Looking in that folder, there is a ghc.exe there, but not a ghc. I'm not too familiar with cygwin so I feel like this is something fairly obvious, but I didn't see it covered on the wiki anywhere. A google search indicated that I might have to override the host mode in the configure state but didn't elaborate, and also I'm not sure how to do that. I also want to make sure that I get a *windows* version of GHC out of the build, as the post I found suggested that might not be the case.
