SDL crossplatform GL issues

SDL Development
1

Hi there.

Im a newbie attempting to write crossplatform code.
Although my SDL demos are running fine on all platforms, on windows, my attempts
to query info with glGetString, including GL_VERSION all return NULL.
Does anyone know of some possible reasons for this?
Ive read in other straight gl forums this may be caused by a bad win rendering
context. Does SDL support the creation of an a cross-platform gl rendering
context, or must I explore the rathole of windows-specific gl code.

thanks for any help or pointers to docs

You must not make any gl* Calls before SDL_SetVideoMode().

After SetVideoMode, the calls should work as expected.
