It looks like the regex library needs the posix library, and in my MINGW / MSYS installation I don't find one (and neither does configure). I have not run into this problem with the regex library but I ran into a similar one when building network. Did you get the regex library after you had already run autoreconf? If so, you need to run autoreconf and ./configure again in the ghc root directory. Hello, I seem to have worded myself poorly. I don't have regex.h on my system. And that seems to be the problem. It doesn't come standard with Mingw and MSYS. Where do I get a posix regex library for Mingw/MSYS? Rene.
