The problem seems to have been that I didn't have gcc installed on windows. I confess I feel very silly for not having thought of this! It's worth noting that the error message is very unhelpful and that the c2hs docs don't mention that gcc is required (it's obvious that it should be needed to compile the generated interfaces, but less obvious that it's needed for c2hs itself). Sorry to waste your time! --Chris Casinghino On Thu, Dec 31, 2009 at 12:07 AM, Chris Casinghino wrote:

I see in the list archives that someone posted this problem a few weeks ago, but there wasn't a response.  So, let me confirm I'm having it too.  I installed the haskell platform on windows and then used cabal to install c2hs.  It put a binary called "c2hs.exe" in "C:\Program Files\Haskell\bin", which appears to be on my path. However, when I go to build some software I've written that uses c2hs, cabal gives me this error:

 c2hs.exe: does not exist

My package builds fine in linux.  The computer I'm at now is running windows xp, service pack 2.  I can try it out on a windows 7 computer tomorrow if that would be helpful.

This is my first attempt to build Haskell software on windows, so it's conceivable I'm doing something silly.  Thanks in advance for your help.
