I don't really understand why do you link in OLDNAMES.lib and you definitely shouldn't have to do this: HA> Property->Linker->Input HA> 'libcmt' is set to be ignored. Also, I think _timezone problem was solved in 2.8 so you should really try 2.8.7, there will be no more fixes in 2.6 branch.

From: ABE Hiroshi on 7 Apr 2008 08:42 VZ, Thank you for your info. As you said, 2.8 solved the problem, but brings another problem regarding wxGLCanvas. Eventually, I found my fault with 2.6. My fault was MultiThread compiler option is mismatched between the wxWigets Lib and the application. The problem regarding wxGLCanvas is still remained on 2.8, which is that LIGHTING doesn't work. All the objects are in dark. And the transform/rotation of OpenGL models doesn't work. All my code is worked on 2.6. I will find the point of the problem. Maybe something is missing, in my app. or wxWidgets.

SetCurrent() doesn't work unless the window is shown, i.e., it doesn't work in a canvas' constructor. - Chris

Actually, the code works fine as I expect with 2.6.4 both on MacOSX and on WIndows XP. The "Dark" problem occurs to the other guy too. He reported it on wxWidgets Forum ( I lost where it was ).

From: ABE Hiroshi on 8 Apr 2008 22:04 Dear wxWidgets Developers, Eventually, I found my fault in my app. I generated glLists in several routines. The glList is created by glNewList - glEndList, actually they are OpenGL objects such as, x-y- z axis and atoms. I found that SetCurrent() must be called in the routines which generate glList. MacOS X version and 2.6.x version seemed to be very easy for the context.
