Hi, recently (last Friday) I had a chance to use MacPorts to install gtk2hs. (Usually I do not have root permissions to do so.) Actually, I only wanted to install the libraries needed to run a gtk2hs application that I've created on another machine. On that other machine gtk was (painfully) installed using http://developer.imendio.com/projects/gtk-macosx/build-instructions and gtk2hs-0.9.13 was then compiled from source. sudo port install gtk2hs began at some stage to compile ghc-6.10.1 which I aborted, because I thought, gtk2hs would not work with ghc-6.10.1. ("port search ghc" on another mac lists ghc-6.8.3, though.) Therefore I tried to only install the needed libraries for the binary. (libglade2, gtk2, etc.) Finally my binary complained about a missing libgdk-quartz-2.0.0.dylib or libgtk-quartz-2.0.0.dylib and I had no idea how to get it from MacPorts. (Initially I did not even see the difference of the two library names "gtk" vs, "gdk".) I don't know if my binary is linked against too many libraries. Is this possible or is the linker smart enough to avoid this? Below is the list of libraries my binary needs. I've just found http://www.haskell.org/haskellwiki/Gtk2Hs#Mac_OS_X and the list of dependencies: glade3 libglade2 gstreamer gst-plugins-base gtksourceview cairo librsvg gtkglext firefox Which one contains "quartz"? Another problem have been the links lib{jpeg,png,tiff}.dylib. I had to remove them from my DYLD_LIBARRY_PATH in order to avoid an error in ApplicationServices: dyld: Symbol not found: __cg_jpeg_resync_to_restart Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO Are the libraries lib{jpeg,png,tiff}.dylib needed at all for gtk?
