GL_ALL_ATTRIB_BITS missing?

My GLEW seems to be missing a define for this.
It's in auto/core/GL_VERSION_1_1. Yet I can't find it's definition anywhere on the opengl.org spec pages -- e.g. in gl.tm or gl.spec, nor is it in the draft gl3.h header. Yet it comes with my nvidia driver. Further, if I copy its defined value and use it in glPushAttrib, it does what I want when rendering through Mesa softpipe. Presumably it would work on my actual GPU as well, though I haven't tested. Also of interesting note, the define given by my nvidia driver seems off by a few bits. few == 12 in this case: tf@shigeru glew grep ALL_ATTRIB_BITS auto/core/* auto/core/GL_VERSION_1_1: GL_ALL_ATTRIB_BITS 0x000fffff auto/core/GL_VERSION_1_1: GL_CLIENT_ALL_ATTRIB_BITS 0xffffffff tf@shigeru glew grep ALL_ATTRIB_BITS /usr/include/GL/gl.h #define GL_ALL_ATTRIB_BITS 0xFFFFFFFF #define GL_CLIENT_ALL_ATTRIB_BITS 0xFFFFFFFF tf@shigeru glew grep ALL_ATTRIB_BITS ~/dev/mesa/include/GL/* /home/tfogal/dev/mesa/include/GL/glew.h:#define GL_ALL_ATTRIB_BITS 0x000fffff /home/tfogal/dev/mesa/include/GL/glew.h:#define GL_CLIENT_ALL_ATTRIB_BITS 0xffffffff /home/tfogal/dev/mesa/include/GL/gl.h:#define GL_ALL_ATTRIB_BITS 0x000FFFFF /home/tfogal/dev/mesa/include/GL/gl.h:#define GL_CLIENT_ALL_ATTRIB_BITS 0xFFFFFFFF My GLEW is admittedly pretty hacked up at this point, so it could just be something I've screwed up. After looking into it though, I'm not even sure if it *should* be there. Could I get confirmation: . That it's not in GLEW 'cause *I* broke something . That the define does exist and I'm not just working too late again..

I'll make sure this is resolved/working before posting a patch series for review. I guess I should get glean/piglit up and running at some point.. is that generally what's done for testing a release? Or is there just such a large set of apps that, "if it works with all of these, it must be good"? -tom ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Thanks again for the help, Nigel.
tom fogal <tfogal@...> writes: > My GLEW seems to be missing a define for this. In my local GLEW, I load every function pointer dynamically. This includes OpenGL 1.1 functionality. As such, instead of hardcoding all of these defines in an auto/src header file, I created a core/GL_VERSION_1_1 and let the function prototypes (+ function pointers) get autogenerated. In generating GL_VERSION_1_1 I used '0x000fffff' for its definition (I think I just copied it from an official header from opengl.org or the like). The parsing code was not setup to recognize lowercase hexadecimal characters for #defines. The attached patch fixes a regex in the parsing code. -tom From 6b9abbefe905b3fe37f693f1b3597ff308c4a43b Mon Sep 17 00:00:00 2001 From: Tom Fogal <tfogal@...> Date: Fri, 31 Jul 2009 19:47:38 -0600 Subject: [PATCH] Fix core parsing issue. 0x000fffff wasn't recognized as a valid definition: the matching regex was only accounting for / allowing uppercase hex digits.
