Hi all,

I’m trying to do an install of OpenGL on Windows using Cabal I type

...

cabal.exe configure OpenGL

And get

sh: runProcess: does not exist (No such file or directory)

What’s the cause?

The OpenGL package uses a ./configure script which needs sh.exe and various other programs. Cabal is trying to run sh.exe but it cannot find it. To build the OpenGL package on Windows you need to build it from within an MSYS shell (which provides sh.exe and the other required tools). There's also a ticket for the bad error message: #403 Bad error message when running ./configure fails to find sh http://hackage.haskell.org/trac/hackage/ticket/403 It should be very easy to improve the error message. Patches welcome. Duncan
