problem building haskell-src

[Nicholas Tung-2]

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,

gatoatigrado@hz:~> cabal install haskell-src
Resolving dependencies...
Configuring haskell-src-1.0.1.4...
Building haskell-src-1.0.1.4...
Preprocessing library haskell-src-1.0.1.4...
shift/reduce conflicts:  2
Implicit import declaration:
    Ambiguous module name `Prelude':
      it was found in multiple packages: base haskell98-2.0.0.0
cabal: Error: some packages failed to install:
haskell-src-1.0.1.4 failed during the building phase. The exception was:
ExitFailure 1

    There are some conflicts with ghc-pkg check; see output for
ghc-pkg list and ghc-pkg check here if it helps [
http://pastebin.com/HR0y6u1a ]. The error came up when I tried to
compile my own sources, but then I ran ghc-pkg hide haskell98 and it
works. (building haskell-src still fails.)

Thanks very much,

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.

Antoine

Hi Antoine,

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

Thanks!

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.

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

Thanks,
