We have sandboxes now, which (I think) weren't there 2 yrs ago.
Try this:
$ mkdir hse # Directory for Haskell
school of expression
$ cd hse
$ cabal sandbox init # Create a new sandbox
$ cabal install gtk2hs-buildtools # Install
gtk2hs-buildtools inside sandbox
$ export PATH=".cabal-sandbox/bin:$PATH" # Add the binaries
installed in (current directory's) sandbox to $PATH
$ cabal install gtk # Install gtk (and
anything else you need)
The above works in my case. Also, if you have a lot of packages installed
in "~/.cabal", then I recommend that you remove them and install them in
sandboxes where they are actually required.
Manually, you'd do it as follows:
$ mv ~/.cabal/packages ~/temporary_package_storage # Long name to avoid
clash, save downloaded package sources
$ rm -rf ~/.ghc ~/.cabal # Remove all packages,
and ghc's knowledge of them
$ mkdir ~/.cabal # Make a new ~/.cabal
directory
$ mv ~/temporary_package_storage ~/.cabal/packages # Reinsert the saved
downloaded package sources
For more info, look here:
https://www.haskell.org/cabal/users-guide/installing-packages.html#developin...
Also, after some time it becomes natural to deal with cabal.
For example, I have that export line in my .zshrc. Thus the sandbox
residing in current directory is always in my path.
Also, a shell function that you may want to use.
cabal-reset () {
if [[ ! -d ~/.cabal-packages ]] ; then # If backup does not
exist
mv ~/.cabal/packages ~/.cabal-packages # Make a backup
fi
rm -rf ~/.ghc ~/.cabal # Nuke everything
mkdir ~/.cabal # Create new ~/.cabal
ln -s ~/.cabal-packages ~/.cabal/packages # Symlink backup to
~/.cabal/packages
}
Hope this helps.

Trying to install the package soegtk.
I am running linux mint 17 with the latest (as of Feb. 28) haskell platform and cabal-install.
I did install gtk2hs-buildtools and put the .cabal/bin in my path.
Cannot install soegtk:
Failed to install glib-0.12.5.4 cabal: Error: some packages failed to install: cairo-0.12.5.3 failed during the configure step. The exception was: ExitFailure 1 gio-0.12.5.3 depends on glib-0.12.5.4 which failed to install. glib-0.12.5.4 failed during the configure step. The exception was: ExitFailure 1 gtk-0.12.5.7 depends on glib-0.12.5.4 which failed to install. pango-0.12.5.3 depends on glib-0.12.5.4 which failed to install. soegtk-0.12.1 depends on glib-0.12.5.4 which failed to install.
Confession: I abandoned Haskell two years ago because of frustration with cabal and hackage. I decided to get back to the language today, and to start with Haskell School of Expression. I immediately run into the problem that the first thing I try to install with cabal does not work.
Thanks for any help. Please tell me things are not just as bad now as they were when I left ;-)
