gtk2hs and MacPorts

[Christian Maeder]

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?

Cheers Christian
