According to the GLES3 spec, blitting between multisample FBOs with different internal formats should not be allowed. The compatible_resolve_formats function implements this check. Previously it had a shortcut where if the Mesa formats of the two renderbuffers were the same then it would assume the blit is ok. However some drivers map different internal formats to the same Mesa format, for example it might implement both GL_RGB and GL_RGBA textures with MESA_FORMAT_R8G8B8A_UNORM. The function is used to generate a GL error according to what the GL spec requires so the blit should not be allowed in that case. This patch just removes the shortcut so that it only ever looks at the internal format. Note that I posted a related patch to disable this check altogether for desktop GL. However this function is still used on GLES3 because there are conformance tests that require this behaviour so this patch is still useful.

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.
