I've made some progress. I've installed c2hs. I'm still puzzled as to why ./Setup configure didn't complain. (snip) 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?
You can do this in a UserHook by either just calling hsc2hs on your .h file in the preBuild phase, or you can override the c2hs preprocessor. As I mention here: http://www.haskell.org//pipermail/haskell/2005-April/015730.html There's an example of using UserHooks to override a preprocessor. Setup.lhs is the right place for the fix until we add more tags to the .cabal file for stuff like this. http://cvs.haskell.org/cgi-bin/cvsweb.cgi/~checkout~/fptools/libraries/Cabal... peace, isaac
