I'd also try hacking in Window.d directly to see if even basic gl commands work, e.g. immediately after window and context creation, try rendering a triangle then tweak the context initialisation to see if it affects anything.

It may help you track down exactly which part of the GL setup is causing problems.


I know almost nothing about OpenGL but using your method(sorta):
void reportGLErrors() {
        GLenum errCode;
        const GLubyte *errString;
        if ((errCode = glGetError()) != GL_NO_ERROR)
                writeln("OPEN GL ERROR: ", errCode);

I get error code 1282 repeatedly.

From a google search someone says:
"First, glGetError() will return 1282 - invalid operation if the GL context is not current (or not yet created). So, create your context first, then call glGetError. And, verify that any parent class or member class does not call GL functions in their constructors or prior to context being created."

Can someone with more OpenGL knowledge clarify what this means?
