I'm trying to build GHC on 64-bit Windows 7. I installed Cygwin, GHC and cloned the main repo but when I run configure I get this error:

I have gcc installed under Cygwin, but for some reason ./configure is looking for an in-tree compiler. I tried passing --with-gcc=/usr/bin/gcc to configure but with no result. Help?

Windows GHC *shall* use in-tree compiler. Windows GHC does *not* use cygwin runtime at all! Now the best way to build GHC on Windows is to use MSYS2: https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Windows/MSYS2. I'd also add that most recent versions are http://sourceforge.net/projects/msys2/files/Base/i686/msys2-base-i686-201402... for 32-bit windows, and http://sourceforge.net/projects/msys2/files/Base/x86_64/msys2-base-x86_64-20... for 64-bit windows. Please, take into account this is *build environment* and in no way is related to gcc compiler and runtime used by GHC on Windows. Cheers, Kyra
