Tim,
I have redefined wxUSE_CANVAS to 1, that is what the warning says. If I didn't, I would get the error that you have copied in your previous post. Namely - "OpenGL required: set wxUSE_GLCANVAS to 1 and rebuild the library". So after I redefine it to 1 as it's required, I get the warning message, which looks more like a "reminder" , that some important value is changed, to me anyhow.
And apologies if I didn't post the build information properly.
Regards, T
