Some drivers do not support certain targets - for example nouveau doesn't do VAAPI, while freedreno doesn't do of the video backends. As such if we enter vdpau when building freedreno/ilo/etc, a vdpau/ folder will be created, empty library will be build and almost immediately removed. Thus keeping an empty vdpau/ folder around. There are two ways to fix this. * add substantial tracking in configure/makefiles so that we never end up in targets/vdpau Downsides: Error prone, as the configure checks and the 'include gallium/drivers/foo/Automake.inc' can easily get out of sync. * remove the folder, if empty, alongside the empty library. Downsides: In the latter case vdpau/ might be empty before the mesa build has started, yet we'll remove it either way. This patch implements the latter option, as the downside isn't that significant, plus the patch is way shorter ;-) v2: use has_drivers to track since TARGET_DRIVERS can contain space, hence neither string comparison nor -n/-z works correctly.

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.
