This was not really a leak per se, but we were referencing the textures for longer than intended. If textures were set via llvmpipe_set_sampler_views() (for fs) and then picked up by lp_setup_set_fragment_sampler_views(), they were referenced in the setup state. However, the only way to unreference them was by replacing them with another texture, and not when the texture slot was replaced with a NULL sampler view. (They were then further also referenced by the scene too which might have additional minor side effects as we limit the memory size which is allowed to be referenced by a scene in a rather crude way.) Only setup destruction (at context destruction time) then finally would get rid of the references. Fix this by noting the number of textures the last time, and unreference things if the new view is NULL (avoiding having to unreference things always up to PIPE_MAX_SHADER_SAMPLER_VIEWS which would also have worked).

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 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.
