Description: I tested gtk2hs by compiling the program given below using ghc 6.10.4. It failed to compile, with the error message:

test.hs:3:0:
Bad interface file: /usr/lib/gtk2hs/imports/gtk/Graphics/UI/Gtk.hi
mismatched interface file versions (wanted "6104", got "6103")

This happened on both i686 and x86_64. Then I compiled gtk2hs myself using ABS, and everything worked. So it looks like gtk2hs needs to be recompiled, that's all.

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce: Try to compile this program using ghc 6.10.4.

import Graphics.UI.Gtk

hello :: (ButtonClass o) => o -> IO ()
hello b = set b [buttonLabel := "Hello World"]

main :: IO ()
main = do
initGUI
window <- windowNew
button <- buttonNew
set window [windowDefaultWidth := 200, windowDefaultHeight := 200,
containerChild := button, containerBorderWidth := 10]
onClicked button (hello button)
onDestroy window mainQuit
widgetShowAll window
