http://bugs.freedesktop.org/show_bug.cgi?id=27261 Summary: GLSL Compiler fails on the following vertex shader Product: Mesa Version: 7.5 Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Mesa core AssignedTo: mes...@li... ReportedBy: kar...@ar... Created an attachment (id=34359) --> (http://bugs.freedesktop.org/attachment.cgi?id=34359) Failing vertex shader The attached vertex shaders do not compile and link when the GLSL Compiler is used. The version of Mesa used is 7.5.2 and it has been configured with --with-driver=xlib. The above vertex shaders are part of the Open GLES conformance suite supplied by Khronos. These shaders compile when the OpenGL drivers supplied by the GPU vendors(NVIDIA, ATI) are installed. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. |

http://bugs.freedesktop.org/show_bug.cgi?id=27261 --- Comment #3 from Brian Paul <bri...@gm...> 2010-03-23 07:15:27 PST --- The fragment shader / preprocessor bug has been fixed for Mesa 7.8. I probably won't get around to the other bugs for a while. I really wish the GLSL didn't allow all those goofy constructors. They're really hard to implement and real shaders seldom use them. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. |

I have also been observing random failures in the GLES conformance suite when I run with MESA. Has there been some memory leaks etc fixed in the new release? -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. |

Has there been some memory leaks etc fixed in the new release? I don't know what would cause random failures. Every so often I find/fix memory leaks but I don't know if that would be related to your issue. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. |

More specifically lots of tests fail in the GL/build section in OpenGL ES Conformance suite. Is there a architectural diagram for the different components in Mesa?

The GL/build section is notoriously complicated but many/most of the tests in that section did pass at one time. There may have been a regression. I'm afraid I don't have time to did into it now though. > Is there a architectural diagram for the different components in Mesa? There's some diagrams focussing on Gallium but I don't have anything handy for Mesa. You can find most things with a little bit of grep'ing. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. |
