As far as I can see, there is a gradual overhead of C libraries involved here. The Platform could ship the following subsets of Gtk2Hs:

cairo cairo+glib+pango cairo+glib+pango+gio cairo+glib+pango+gio+gtk

It's a question of how big the tar ball is and how much work it is to bundle the C libraries with the Platform.

Cheers,

That's why I voted for including just cairo.

it's low overhead, high quality and gives your haskell install access to cross-platform graphics capability. _______________________________________________

We wouldn't bundle the C source (as we don't e.g. for GL or Regex.c currently)

I understand, but you only need libcairo and some sort of -dev version of libcairo. as you start to lump stuff on top of it, then there's more to install, and you can easily end up in dependency hell where things won't install because of some annoying dependency. For example, the cabal version of gtk2hs installed very smoothly but I think I had to install 2 cabal packages and at least 4 -dev system libs before I was done. really, access to screen graphics of some sort is a wishlist item. Another option would be to include something that generates postscript output only. The nice thing about cairo is that it will do that in addition to giving you a screen display should you desire, and all with the same code :-) Brian
