The formats.c code's "datatype" value is "what does this value mean", i.e. unorm or snorm or float, and is the return value from the GL_TEXTURE_RED_TYPE class of queries. The depth formats were marked as GL_UNSIGNED_INT, which is what we use for integer, and not what we should be returning from the glGetTexLevelParameter. In texstore, we were inappropriately using it as an argument to _mesa_unpack_depth_span() that was expecting a value like GL_UNSIGNED_INT or GL_UNSIGNED_SHORT. Just hardcode _mesa_unpack_depth_span()'s arguments for now, though it looks like the consumers of that interface would be happier with using MESA_FORMAT. Reviewed-by: Brian Paul <brianp@vmware.com>
File: docs/README.WIN32 Last updated: 23 April 2011 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. 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.
