We don't actually have the code for the shader cache just yet, but this configure machinery puts everything in place so that the shader cache can be optionally compiled in. Specifically, if the user passes no option (neither --disable-shader-cache, nor --enable-shader-cache), then this feature will be automatically detected based on the presence of a usable SHA-1 library. If no suitable library can be found, then the shader cache will be automatically disabled, (and reported in the final output from configure). The user can force the shader-cache feature to not be compiled, (even if a SHA-1 library is detected), by passing --disable-shader-cache. This will prevent the compiled Mesa libraries from depending on any library for SHA-1 implementation. Finally, the user can also force the shader cache on with --enable-shader-cache. This will cause configure to trigger a fatal error if no sutiable SHA-1 implementation can be found for the shader-cache feature. Bug fix by José Fonseca <jfonseca@vmware.com>: Fix to put conditional assignment in Makefile.am, not Makefile.sources to avoid breaking scons build. Note: As recommended by José, with this commit the scons build will not compile any of the SHA-1-using code. This is waiting for someone to write SConstruct detection of the available SHA-1 libraries, (and set the appropriate HAVE_SHA1_* variables). Reviewed-by: Matt Turner <mattst88@gmail.com>
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 osmesa mesagdi to build classic mesa Windows GDI drivers; or 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.
