[wxhaskell-users] Undefined reference to wxGLCanvas::*

[Bas v. D. <bas...@ho...>]

Hello,

When making the wx samples I got the following error:

bas@bassbox ~/development/haskell/wxhaskell/samples/wx $ make
ghc -package wx -o BouncingBalls BouncingBalls.hs
/usr/lib/libwxc-gtk2.6.2-0.10.1.so: undefined reference to

I configured wxHaskell --with-opengl and my wxWindows implementation (on 
Gentoo Linux) has OpenGL support:

emerge x11-libs/wxGTK -vp

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] x11-libs/wxGTK-2.6.2-r1  USE="X doc joystick opengl sdl 
unicode -debug -gnome -odbc" 0 kB

What is wrong here?
