From: Rob
Subject: [SDL] SDL pre-release
OpenGL fails on the zipped pre-release source accessible from
http://www.libsdl.org/svn.php.
Appears to be following lines in sdl_wing.c (lines 341-345):
wglext = (const char *)this->glGetString(GL_EXTENSIONS);
if ( !SDL_strstr(wglext, "WGL_EXT_swap_control") ) {
this->gl_data->wglSwapIntervalEXT = NULL;
this->gl_data->wglGetSwapIntervalEXT = NULL;
}
glGetString is a null pointer, as are other gl function pointers, so call
fails. Never looked at sdl source before, so no further than that as yet.
