I have made a package for getting and installing Gtk2HS from darcs (gtk2hs-darcs), on Arch Linux. Someone is reporting to me this:

And I responded him with:

I think I may know what is going on, but I just can't believe no developer of gtk2hs is having gstreamer, and a 32 bits system. ;-)

gtk2hs is using c2hs, to make a .hs file from .chs, by consulting C headers files.
gstreamer/Media/Streaming/GStreamer/Core/GObjectHierarchy.chs
choose to import only CULong, because on the author system (which must have 64 bits), this is what the C file header return. But because you have 32 bits (correct me if I am wrong), your C header file return a 32 bit value, so CUInt must be imported too.

So you would have to make a new clean install, but stop the system after darcs got src installed.

Then edit in gstreamer/Media/Streaming/GStreamer/Core/GObjectHierarchy.chs
to remove '(CULong)' on the following line:
import Foreign.C.Types (CULong)
that way, it will import all the types, CUInt included. Or just make it '(CULong,CUInt)'.

I am new to Arch, new to Haskell, and new to Gtk2HS, so I may be out of track however.

Not sure I am Ok, and a developer could verify if there is other files like this. The package can be found http://aur.archlinux.org/packages.php?do_Details=1&ID=14976&O=0&L=0&C=0&K=gtk2hs&SB=n&SO=a&PP=25&do_MyPackages=0&do_Orphans=0&SeB=nd

Only CULong is declared in the files, but c2hs seems to generate references to CUInt.

I'm having the problem on 32-bit Ubuntu. I don't recall hitting any glitches when I compiled it on my 64-bit Ubuntu machine.

My fix: I just added CUInt to the imports. Diff attached.

I'm having a lot of trouble getting entry completion working, as my little program in http://hpaste.org/5436 shows. Could you please update the "entry completion" section of the tutorial found at http://darcs.haskell.org/gtk2hs/docs/tutorial/tutorial.t2t ? It would help me a lot! thanks --Jacques
