Hi,
I tried compiling this program:
module Main where
import Graphics.UI.WX
main :: IO ()
main
= start hello
hello :: IO ()
hello
= do f <- frame [text := "Hello!"]
quit <- button f [text := "Quit", on command := close f]
set f [layout := widget quit]
with wxhaskell 0.11.0 (latest darcs version), ghc 6.8.3, libwxgtk
2.8.7.1-0ubuntu3 on Kubuntu 8.04 and everything builds fine, but when I try
to run it I get:
./wxhaskelltest: symbol lookup error: /usr/lib/libwxc-gtk2.8.7-0.11.0.so:
undefined symbol: _ZNK7wxPanel14GetDefaultItemEv
Trying
strings /usr/lib/libwxc-gtk2.8.7-0.11.0.so | grep wxPanel14
gives:
_ZNK7wxPanel14GetDefaultItemEv
So the library should be in order.
Any help with this?
Kind regards,
Jeroen Janssen.
