[Solved] Unable to find an entry point : error

Posted Thursday, 10 June, 2010 - 13:08 by Soundbomber in

Hello, I was wondering if anyone could help with a recent problem I have encountered with OpenTK 1.0-beta 3?
I have an app which runs fine on machines with OpenGL version 2 installed, however, tested on a couple of machines with version 1.3 installed I get the following error:
"Unable to find an entry point named 'glGenBuffers' in DLL 'opengl32.dll'"
The error occurs when I execute the following code :
GL.GenBuffers(n as integer, buffers() as integer)
I have ensured that the machines in question have the latest graphics drivers installed and as I mentioned the app works fine on other machines (XP & Windows 7).
Any suggestions anyone?

GL.GenBuffers() requires OpenGL 1.4 or higher. For older cards, try checking whether the ARB_vertex_buffer_object extension is supported and, if yes, use GL.Arb.GenBuffers().

The older machines do support ARB vertex buffer objects, and my app now works with a couple of tweaks.
Thanks for your help.
