Thank you for your response. If I execute "ghc-pkg list gtk" I receive this output:

ghc-pkg list gtk /usr/local/Cellar/ghc/7.0.4/lib/ghc-7.0.4/package.conf.d /Users/tanjapiechnick/.ghc/i386-darwin-7.0.4/package.conf.d

But "ghc-pkg check" gives me no results

ghc-pkg check

Is this the issue?

if you have only very recently built gtk etc via mac homebrew, you need to build the head version of gtk2hs and family

Ok, and where can I get these informations? Am 07.06.2012 um 02:42 schrieb Carter Schonwald:

Hey Haskell-Cafe,

I would like to run GTK2HS on my Mac 10.6.8 but after the successful installation with Homebrew of all modules (GTK+, GTK2HS) I get this failure message:

Prelude> :l guitest.hs

guitest.hs:1:8: Could not find module `Graphics.UI.Gtk': Use -v to see a list of the files searched for. Failed, modules loaded: none.

Just to confirm for us, as the same user can you please run the following:

ghc-pkg list gtk

As well as:

ghc-pkg check

...

I always changed my PATH. This is the content of my PATH:

/usr/bin /bin /usr/sbin /sbin /usr/local/bin /Developer/usr/bin /Users/tanjapiechnick/.cabal/bin $HOME/.cabal/bin

I don't think this is a PATH problem; possibly a problem with library paths.

...

Is that correct? Where is the mistake?

Thank you for any help! Greetings from Namibia

All right. After a re-installation I could load my GTK2HS example successfully. But I received another error. What is the meaning of that? A wrong architecture?

This means that you in fact _don't_ have the Haskell gtk package installed (in the sense that GHC knows about it), which is why you can't use it.

No, this in fact is good: it means that you don't have a problem with your Haskell libraries.

I'm not too sure about this; Carter can hopefully tell you more about this (specifically which packages need to be built from HEAD, etc.). But you're going to want to use the darcs repository at http://code.haskell.org/gtk2hs/ .

That's a 64bit / 32bit problem. The gtk library you installed via homebrew is probably 64bit while the GHC you use (7.0.4) seems to be 32bit. Either you reinstall GTK with 32bit support, or you use the 64bit version of the recently released Haskell Platform.

The 7.0.4 HP package strongly suggested use of the 32-bit package even on 64-bit systems, so this is very likely. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
