Before, we weren't setting step rate so we got whatever old value happened to be lying around. This can lead to some interesting rendering errors. In particular, if you run the OpenGL ES CTS with dEQP-GLES3.functional.instanced.types.mat2x4 immediately followed by one of the dEQP-GLES3.functional.transform_feedback.* tests, the transform feedback test gets stale instancing data from the other test and fails. The only thing that is causing this to not be a problem today is that we use meta for clears and meta is setting up vertex buffers via the VBO or non-interleaved path and setting step_rate to 0 for us. When blorp depth/stencil clears are enabled, meta is no longer sitting between the two tests and the stale data starts causing noticeable problems.

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see https://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
