It's a good idea. I believe the problem I had when I tried it last was that cabal doesn't like ".." as part of an hs-source-dirs directive. But my memory is a bit fuzzy. After I have a look at the various cabal-1.18 patches floating around it seems like a good thing to think about.
Of course, the idea is that our moderately experienced Haskeller will be installing from Hackage, not darcs, and so most of these things are aimed at very experienced Haskellers who need to hack on gtk2hs. But your point stands: it would be nice to have more and/or easier instructions. See also bootstrap.sh, which builds both the gtk and gtk3 packages. ~d On 2013-09-22 11:00, Ben Gamari wrote: > Since Daniel Wagner's patch[1] from 11 July 2012, gtk/gtk.cabal in the > gtk2hs repository declares the package name to be gtk3.
