I just installed gtk2hs on Windows last week (for Leksah development). I downloded and unzipped the following files to a gtk folder: gtk+-bundle_2.22.1-20101227_win32.zip gtksourceview-2.10.0.zip gtksourceview-dev-2.10.0.zip libxml2_2.7.7-1_win32.zip libxml2-dev_2.7.7-1_win32.zip I added the bin of the gtk folder to my path. Then just installed gtk2hs the usual way (cabal install gtk2hs-buildtools, cabal install gtksourceview2) It failed then with linker errors, until I realised, that I had other gtk installations in the path (Pidgin, ghostview). After I took them out all went fine. Jürgen -- View this message in context: http://haskell.1045720.n5.nabble.com/Can-t-build-Gtk2hs-on-Windows-tp4371091...
