I've made some progress. I've installed c2hs. I'm still puzzled as to why ./Setup configure didn't complain. My cabal file is now: Name: Ping Version: 0.0 License: BSD3 Author: Dominic Steinitz Synopsis: The Haskell equivalent of ping Executable: ping Main-Is: test.hs Other-modules: IP_ICMP And cabal magically finds the IP_ICMP.chs file and preprocesses it. However, I need to execute the following: c2hs ip_icmp.h IP_ICMP.chs not just c2hs IP_ICMP.chs How do I get cabal to do this? I saw this http://www.haskell.org//pipermail/haskell/2005-April/015728.html. Does that mean I need to modify cabal? Or can I use UserHooks? Are there any examples? Thanks, Dominic.

I am trying to migrate some old code to cabal. It uses c2hs. Now I wasn't sure I had c2hs installed so I ran cabal anyway.
1. Why isn't configure telling me where c2hs is? It tells me where hsc2hs is! 2. Why is cabal telling me it can't find a source when the source is present?
Thanks, Dominic.
Here's ping.cabal:
Name: Ping Version: 0.0 License: BSD3 Author: Dominic Steinitz Synopsis: The Haskell equivalent of ping
Executable: ping Main-Is: test.hs Other-modules: IP_ICMP.chs
When I run ./Setup configure, I didn't see any message saying whether c2hs was installed and when I run ./Setup build I get the following:
[dom@tility ping]$ ./Setup build Preprocessing executables for Ping-0.0... can't find source for IP_ICMP.chs in ["."]
But the source is there:
[dom@tility ping]$ ls codes.hs dist/ ip_icmp.h ping.cabal Setup* Setup.hs test.hs CVS/ IP_ICMP.chs Makefile ping.cabal~ Setup.hi Setup.o
