createProcess fails to find executable in Windows

25 Oct 2012

      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
