[Haskell-cafe] createProcess fails to find executable in Windows

Hi all, Consider the following program: module Test where

import System.Process (readProcess)

main :: IO () main = readProcess "git" ["describe", "--tags"] "" >>= putStr

In Windows I get the following behaviour:

git --version git version 1.7.10.msysgit.1

...

ghc --version The Glorious Glasgow Haskell Compilation System, version 7.6.1

...

runghc Test Test: git: createProcess: does not exist (No such file or directory)

The same happens with GHC 7.4.2. In Linux, however, it works as expected: $ git --version

git version 1.7.9.5 $ ghc --version The Glorious Glasgow Haskell Compilation System, version 7.4.1 $ runghc Test.hs Package-2.0-68-gacaf77a

Can anyone reproduce this result in Windows? Is this a bug or am I doing something wrong? Thanks, Pedro
