Always enable the use of pre-compressed texture data. The ability to perform on-line compression still requires the presence of libtxc_dxtn or an explicit driconf over-ride. Applications that just want to submit precompessed data when an on-line compressor is not available can look for the GL_EXT_texture_compression_dxt1 and GL_ANGLE_texture_compression_dxt[35] extensions. v2: Only enable the extensions that do not require on-line compression by default. The previous statement "This should not impact many (if any) real applications." proved to be false for at least Sauerbraten. This application mostly submits pre-compressed data, but it also can submit uncompressed data that it asks the driver to compress.

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.
