How to upgrade gtk2hsC2hs?
cabal, glib, gtk, gtk2hs, haskell
Solution
It's part of the gtk2hs-buildtools package.
$ cabal install gtk2hs-buildtools
(maybe with the `--global` flag, depends on how you want to install packages in general) should provide you with the newest version that should be able to build the latest `gtk2hs` packages.
Since the old `gtk2hsC2hs` is in `/usr/bin`, make sure that the new one is either installed there (replacing the old) or in a directory appearing before `/usr/bin` in your `$PATH`. A default `cabal install` installs executables (on Linux) in `$HOME/.cabal/bin`, so it would be a good idea to have that the first directory in the `$PATH`.
Problem
I am trying `cabal install glib-0.12.3` under my Ubuntu 11.10 using cabal-install 0.10.2. However, it shows the following error messages: ``` setup: The program gtk2hsC2hs version >=0.13.5 is required but the version found at /usr/bin/gtk2hsC2hs is version 0.13.4 cabal: Error: some packages failed to install: glib-0.12.3 failed during the configure step. The exception was: ExitFailure 1 ``` After half an hour's search, I cannot find where this `gtk2hsC2hs` is. I dug into places like http://code.haskell.org/gtk2hs/tools/c2hs/, but could not seem to find the right version. How could I upgrade my gtk2hsC2hs? Thanks!
