I'm having some existing code that I'm not able to run without gtk2hs. But I can't get it installed. I tried with cabal before but found out that the correct solution for now is to build from darcs. So I do :

darcs get --lazy http://code.haskell.org/gtk2hs
cd gtk2hs
export PATH=$HOME/Library/Haskell/bin:$PATH
sh bootstrap.sh

And get this :

could not be found.

I'm on osx with most recent versions of cabal and darcs.

  • Do you have GTK installed? It looks to me like for some reason Cabal can't find the actual GTK libraries... – MathematicalOrchid Oct 29 '13 at 08:56
  • @MathematicalOrchid how did you found that? It's just that to me errors looks like nonsense, what does they trying to say? `The pkg-config package cairo version >=1.2.0 is required but it could not be found` — is it that pkg-config outdated? Or that cairo outdated? I.e. I am having GTK, but experiencing the same problem. – Hi-Angel May 17 '15 at 14:10
  • @MathematicalOrchid From the author's problem *(mine had only one error)* I can infer that the version error rather about a cairo, and still I am having a problem with understanding the message: why does it trying to install «0.12.4.1» version, but complains about the «1.2.0» version? – Hi-Angel May 17 '15 at 14:19

You must install the gtk C libraries before you install the Haskell bindings to them. Visit the installation instructions and check the section for your operating system if you need instructions on how to do this.
