[solved] FBO not supported? :(

I've just bought a brand new sony laptop, however the game I've been developing does not run on it. I get the error: Unable to find an entry point named 'glGenFramebuffersEXT' in DLL 'opengl32.dll'. Annoyingly I've used FBO objects A LOT. They are pretty fundemental to the graphics in my game. Any ideas as to how I could get around this? - There don't seem to be any graphics card driver updates available either.

I've run the automatic update utility from intel - it says that my drivers are up to date (8.15.0010.2226).

[edit] and if I uinstall my drivers then run the utility, it just points me to the same windows 7 exe which I've already run.

I've also posted on the OpenGL forums you suggested: http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showflat&Numb...

I've also posted on some Intel forums: http://communities.intel.com/thread/17776

Is there anything else you would recommend? - I'm really at my wits end with this. :(

Something else: if you look at the Spec:

http://software.intel.com/en-us/articles/quick-reference-guide-to-intel-...

..and if you scroll down to the OpenGL bit, it seems to promise OpenGL support based upon the chipset, however my chipset (U5400) is not listed. Could this mean that it doesn't support OpenGL beyond 1.1? - I just really want to know whether I should invest any more energy into trying to get this to work, or whether I should give up and have the laptop returned.

In the upper part of the Extension Viewer window, is there a dropdown box that states "GDI Generic" or similar? Is this the only choice?

Does changing the desktop color depth change anything regarding the reported OpenGL version? Disabling/enabling Aero/Glass and other effects?

There is no other choice.

I've tried changing to 16-bit colour and totally enabling/disabling Aero features - no change. :(

Then you are still stuck in software emulation hell. Given the number of driver installations you have tried so far, I would honestly recommend reinstalling the OS from scratch - it is often enough to get the drivers working.

Although, you might be better off returning it before your 30 days are up, and getting a laptop with an ATI/NVidia graphcis card. The performance will be better, and the OpenGL support is far, far better.

I don't think I can go through the pain of reinstalling windows (considering that I'll have to do it over USB) only then to find that I'm in the same position. I think I'll just send it back. I've already wasted far too much time getting the damned thing to work. :(

Well actually I'm going to have one last-ditch attempt: I'm going to pop to the shops now to buy a 4gb USB stick so that I can reinstall Windows 7. I will then attempt to freshly install the intel drivers, with nothing else to interfere. If this doesn't work, I'll pull out a few hairs, swear fervently, then pack the little devil into it's box and mail it back to Amazon.

[edit]

Woot! The fresh install did the trick. Full support up to 2.1, and 70% for 3.0! Thanks for the help. :)

Glad to hear it's working! This is a pretty nice machine and it would be sad to be marred by driver issues.
