Hi,
I've had my share of problems with this of late as well, but managed to
get everything working. You have to indeed manually enable OpenGL
support when building wxWidgets.
To do so, you need to edit the 'master setup.h file'. This file can be
found at "include/wx/<your build platform>" (as described at
<http://wiki.wxwidgets.org/Setup.H>). Change the value of
"WX_USE_GLCANVAS" from 0 to 1. Then, rebuild the lot.

Whatever your wxWidgets version, I believe you must explicitly enable
OpenGL support when building wxWidgets (OpenGL support is disabled by
default).

Hi Ed,
I am using 2.8.7, but the latest stable version should work as well.

If I want to use wxWidgets with OSG, do I need a particular
version of
wxWidgets?
