The driver must support at least one of PIPE_CAP_TGSI_FS_COORD_ORIGIN_UPPER_LEFT PIPE_CAP_TGSI_FS_COORD_ORIGIN_LOWER_LEFT and one of PIPE_CAP_TGSI_FS_COORD_PIXEL_CENTER_HALF_INTEGER PIPE_CAP_TGSI_FS_COORD_PIXEL_CENTER_INTEGER otherwise glsl_to_tgsi will fire an assert. ORIGIN_UPPER_LEFT is the default convention, and is supported by all mesa drivers, hence it seems reasonable to always report the caps to be enabled. On gles ORIGIN_LOWER_LEFT is generally not supported, so we rely on the caps reported by the host that depend on whether we run on an GL or an EGL host. For PIXEL_CENTER it is completely host driver dependend on what is supported, and since we do not report the actual host driver capabilities it is best to mark both as supported, this is how it works for a GL host too.

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.
