C++ OpenGl tutorial translated to Assembly, the prototypes from masm32 includes conflict with the ones in C++ and my program runs but it crashes on CreateWindowEx.

Unfortunately I can't exactly find what's wrong with my code =/

2) Masm's faulty prototypes. Instead of using the "REAL8" data type, it will simply use two "DWORD"s in a row, so that it takes up the same amount of space. Why did they do this?

You want to talk ugly:

Here is just one of the faulty protos you referred to followed by some code to call the function (written in ASM) i found:

gluPerspective PROTO :DWORD,:DWORD,:DWORD,:DWORD,:DWORD,:DWORD,:DWORD,:DWORD

push _100d0
push _100d1
push _01d0
push _01d1
push dword ptr [_aspd+4]
push dword ptr [_aspd]
push _45d0
push _45d1
call gluPerspective

Compare that to your fixed up proto and your invoke:

gluPerspective PROTO :REAL8, :REAL8, :REAL8, :REAL8

invoke gluPerspective,$dConst(45.0),dRatio,$dConst(0.1),$dConst(100.0)

which lays down nicely with the function definition from MSDN:
void gluPerspective(
GLdouble fovy,
GLdouble aspect,
GLdouble zNear,
GLdouble zFar
);

And that is just one example.
I don't know how anyone could work with the masm32 GL includes that way.

Savage, your Xopengl32.inc is destined to be in every household. Keep up the good work

edit~
I see you cleaned it up some
GLprotos.inc it is then - hehe

Nice grunt work.
