Note: This patch appears to violate older OpenGL and OpenGLES specs.
The OpenGLES GLSL 3.1 and OpenGL GLSL 4.3 specifications both remove
the requirement for the output and input centroid qualifiers to match.
The deqp
dEQP-GLES3.functional.shaders.linkage.varying.rules.differing_interpolation_2
test wants the newer OpenGLES 3.1 specification behavior, even for
OpenGLES 3.0. This patch simply removes the checking in all cases.
The OpenGLES 3.0 conformance test suite doesn't appear to require the
older ("must match") spec behavior.
For reference, here are the relavent spec citations:
The OpenGL 4.2 spec says: "the last active shader stage output
variables and fragment shader input variables of the same name must
match in type and qualification (other than out matching to in)"
The OpenGL 4.3 spec says: "interpolation qualification (e.g., flat)
and auxiliary qualification (e.g. centroid) may differ."
The OpenGLES GLSL 3.00.4 specification says: "The output of the
vertex shader and the input of the fragment shader form an
interface. For this interface, vertex shader output variables and
fragment shader input variables of the same name must match in type
and qualification (other than precision and out matching to in)."
The OpenGLES GLSL 3.10 Specification says: "interpolation
qualification (e.g., flat) and auxiliary qualification (e.g.
centroid) may differ"

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.
