This fixes an assertion failure in [at least] one of the Unreal Engine Linux demo/games that uses DXT1 compression. Specifically, the "Vehicle Game". At some point, the game ends up trying to blit mip level whose size is 2x2, which is smaller than a DXT1 block. As a result, the assertion in the blit path is triggered. It should be safe to simply make sure we align the width and height, which is sadly an example of compression being less efficient. NOTE: The demo seems to work fine without the assert, and therefore release builds of mesa wouldn't stumble over this. Perhaps there is some unnoticeable corruption, but I had trouble spotting it. Thanks to Jason for looking at my backtrace and figuring out what was going on. v2: Use NPOT alignment to make sure ASTC is handled properly (Ilia) Remove comment about how this doesn't fix other bugs, because it does.

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 http://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.
