I'm trying to follow the instructions provided on http://www.haskell.org/haskellwiki/Gtk2Hs to install Gtk2Hs in Windows 7 (64 bit) and running into problems. Originally I was trying to get wxHaskell installed, but it kept crashing trying to build the monolithic library due to an apparent bug in the latest port of GCC, so after talking with some of the people in #haskell I was advised that Gtk2Hs was better supported and might be easier to get working. For the most part, that appears to be true but I (as well as several others it seems) am running into a problem where cabal can't seem to find quite a few of the Gtk+ libraries (specifically z, cairo, gobject, glib, and intl). Near as I can tell everything should be functioning, and running pkg-config --modversion glib-2.0 outputs "2.20.3" so at least pkg-config seems to be able to find glib. Looking in the Gtk+\lib\pkgconfig folder I see pc files for everything but z and intl listed. Running cabal install gtk2hs-buildtools also succeeds, it's only when I get to the cabal install gtk step that things fail. cmd console output for the usual environment variables: INCLUDE: C:\libxml\include;C:\Program Files (x86)\Gtk+\include LIB: C:\libxml\lib;C:\Program Files (x86)\Gtk+\lib PKG_CONFIG_PATH: C:\libxml\lib\pkgconfig;C:\Program Files (x86)\Gtk+\lib\pkgconfig I trimmed the PATH output below for everyones sanity. The vast majority was stuff in the Windows folder or one of dozens of entries dumped in there by some version or other of Java.
