On some systems it is problematic to have the shader cache enabled by default. This adds a build option to support the disk cache but keep it disabled unless the environment variable MESA_GLSL_CACHE_DISABLE=false. For example, on Chrome OS, Chrome already has it's own shader disk cache implementation so it disables the mesa feature. Tests do not want the shader disk cache enabled because it can cause inconsistent performance results and the default 1GB for the disk cache could lead to problems that require more effort to work around. The Mesa shader disk cache is useful for VMs though, where it is easy to configure the feature with environment variables. With the current version of Mesa, Chrome OS would need to have a system-wide environment variable to disable the disk cache everywhere except where needed. More elegant to just build Mesa with the cache feature disabled by default.

README.WIN32
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.
