Hi all,

    I'm having some trouble building haskell-src. If anyone could give me any pointers, I'd appreciate it very much. The error is with an ambiguous module name,

Hi Nicholas,

The haskell-src package needs to be patched to work with GHC 7.2.

If using GHC 7.0 is an option, it should work with that.

A similar package which does work with GHC 7.2 is haskell-src-exts:

http://hackage.haskell.org/package/haskell-src-exts

It has support for many haskell language extensions, so the AST types are a bit more complex.

Hi Antoine,

   I'm sorry for not specifying, I am using ghc 7.0.3

Maybe I'm miss-understanding the problem.

Here's a reference for a similar error:

http://hackage.haskell.org/trac/ghc/ticket/4958

But it shouldn't have been a problem until GHC 7.2.1.

If your problem is the same, editing the .cabal file to remove the reference to haskell98 should be enough - but that can be tricky if you're not familiar with the process.

Antoine

Yes, removing the "haskell98" reference seemed to make it work. Thanks, Nicholas
