I'm getting the exact same error has Doug. My stacks look pretty much the same as Doug's as well.
I'm also running on x64 Ubuntu 8.04, but with GeForce 8800GT and NVIDIA driver version 173.14.12. gl-extensions is reporting that I have both GL_ARB_shader_objects and GL_EXT_framebuffer_object as well. -Bill ----- Original Message ---- From: Joe Groff <[EMAIL PROTECTED]> To: [email protected] Sent: Tuesday, September 30, 2008 12:51:11 PM Subject: Re: [Factor-talk] OpenGL error On Tue, Sep 30, 2008 at 9:35 AM, Doug Coleman <[EMAIL PROTECTED]> wrote: > Hi Joe, > > I'm running x64 Ubuntu 8.04 with a GeForce 8600 GT and the NVIDIA > driver.

NVidia's GLSL compiler is clever enough to optimize away vertex attributes that aren't actually used in the linked shader program; this causes the "surface_color" attribute to disappear in the shader program that draws the textured sphere (which doesn't need a surface color, seeing as it uses a texture to color itself), and an OpenGL error gets raised when the code tries to set that attribute. That doesn't seem at all related to your framebuffer error, though. -Joe ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Factor-talk mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/factor-talk ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Factor-talk mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/factor-talk
