[wxhaskell-users] WxHaskell segfault on Debian Sarge

[Simon G. <si...@gu...>]

Hi,

I've used WxHaskell 0.8 successfully for a while now, both on Windows
and Debian unstable.  However, I'm now trying to use it on Debian
sarge, and experiencing Gtk and Glib critical failures, and segfaults
upon starting the program in GHCI.

Specifically:


$ ghci HelloWxWorld.hs

Segmentation fault

This is running on the machine on which I built wxHaskell from
source.  I'm experiencing the same symptoms with both wxHaskell 0.8
and 0.9.4.

Any suggestions?  Is anyone successfully using wxHaskell on Debian
sarge now?

I don't have many other wxWidgets programs, but I can successfully run
some wxPython scripts on the same machine.


cheers,
Simon

PS: In case anyone thinks it matters, here's my Haskell code:

{- demonstrates the use of a simple menu, statusbar, and dialog -}
module Main where

import Graphics.UI.WX

main :: IO ()
main
  = start hello

hello :: IO ()
hello
  = do -- the application frame
       f      <- frame         [text := "Hello world!", clientSize := sz 300 200]

       -- create file menu  
       file   <- menuPane      [text := "&File"]
       quit   <- menuQuit file [help := "Quit the demo", on command := close f]

       -- create Help menu
       hlp    <- menuHelp      []
       about  <- menuAbout hlp [help := "About wxHaskell"]

       -- create statusbar field
       status <- statusField   [text := "Welcome to wxHaskell"]

       -- set the statusbar and menubar
       set f [ statusBar := [status]
             , menuBar   := [file,hlp]
             -- as an example, put the menu event handler for an about box on the frame.
             ,on (menu about) := infoDialog f "About wxHaskell" "This is a wxHaskell demo"
             ]
