Where can I find C++ 3.1 header files 4 OpenGL ?

What “C++ 3.1” are you talking about?

Borland C++ 3.1?
GCC 3.1?
Watcom 3.1?
and so on…

Borland C++ 3.1

Borland 3.1 is a 16 bit DOS compiler that can do some Win16 stuff. OpenGL is not supported on DOS or Win16 with the exception of a MESA (www.mesa3d.org) port to DJGPP.

I suggest you grab yourself a REAL 32 bit compiler (OpenGL headers are included as far as I recall).

You can get a free console only version of the Borland C++ 5.5 compiler here:


Or the Bloodshed Dev-C++ that is for free as well and comes with a IDE:
