http://sourceforge.net/projects/msys2/ is *much* better than stock msys. I've successfully built ghc HEAD quite recently (a month ago or so) using it.
Interesting! There appears to be about zero documentation, but I unpacked the tar ball (which has pre-built binaries), put it in c:/msys32, added c:/mys32/bin to my PATH, and tried.
Starts well, but two problems.
* I get lots of this (non-fatally):
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LC_ALL = (unset),
LANG = "ENG"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
* But then I get this error which brings things to a halt:
checking for gfind... no
checking for find... /usr/bin/find
checking for sort... /usr/bin/sort
checking for GHC version date... inferred 7.7.20131001
checking for ghc... /cygdrive/c/fp/HP-2013.2.0.0/bin/ghc
checking version of ghc... 7.6.3
GHC path canonicalised to: /cygdrive/c/fp/HP-2013.2.0.0/bin/ghc
checking build system type... Invalid configuration `i686-pc-msys': system `msys' not recognized
configure: error: /bin/sh ./config.sub i686-pc-msys failed
Does anyone have ideas for fixing this? Kyra, how did you get past these?
