Runtime crash when attempting to use glClearTexImage()

Okay, I figured out the issue, it was a lot simpler than I thought. I was calling glewInit() before creating a window/context with glut, which was casing it to fail to initialize. Changing the order fixes it.

glClearTexImage is available only if the GL version is 4.4 or greater.

It is strongly recommended to check for the expected functionality.

as I mentioned, my GPU supports GL 4.4. glGetString(GL_VERSION) in the code even returns 4.4.

After having looked at it and researched some more, it seems the issue actually has to do with Eclipse CDT not being able to parse the function since it's defined as a macro in glew.h, and isn't actually defined until runtime (or something along those lines.) What's happening thereafter is either the function isn't actually getting defined, or I'm using it wrong without the compiler stopping me.

Not sure if this makes it more of an Eclipse issue than a GLEW one, or if there's a way to get Eclipse to parse the functions properly.
