SDL+OpenGL fullscreen in Win98

Hello,

I’m having problems getting SDL+OpenGL apps to run
fullscreen in Win98. I using the testgl program,
compiled under linux with mingw32, and a voodoo3
with the latest drivers under win98.

testgl works fine in windowed mode, but when attempting
to go fullscreen, the display switches modes and goes
black for a few seconds, then I get a little Windows
dialog that informs me that there was an Invalid page
fault in 3dfxogl.dll.

The only output from testgl is on stderr:
Couldn’t set GL mode: Unable to make GL context current

Has anyone else encountered this problem?

I’ve only just recently started working with cross
compiling and using OpenGL under windows, so any help
will be appreciated.

Thanks,

Has anyone gotten SDL-1.1/test/testgl to cross-compile
on linux and run fullscreen on windows 98 with a voodoo3?

If so, I’d like to compare settings and methods to find
out why I am getting an invalid page fault in 3dfxogl.dll

(fullscreen works fine on the other windows machine I tested
on, equipped with a geforce)
