We resolved the implicit version directive when processing control lines, such as #ifdef, to ensure any built-in macros exist. However, we failed to resolve it when handling ordinary text. For example, int x = __VERSION__; should resolve __VERSION__ to 110, but since we never resolved the implicit version, none of the built-in macros exist, so it was left as is. This also meant we allowed the following shader to slop through: 123 #version 120 Nothing would cause the implicit version to take effect, so when we saw the #version directive, we thought everything was peachy. This patch makes the lexer's per-token action resolve the implicit version on the first non-space/newline/hash token that isn't part of a #version directive, fulfilling the GLSL language spec: "The #version directive must occur in a shader before anything else, except for comments and white space." Because we emit #version as HASH_TOKEN then VERSION_TOKEN, we have to allow HASH_TOKEN to slop through as well, so we don't resolve the implicit version as soon as we see the # character. However, this is fine, because the parser's HASH_TOKEN NEWLINE rule does resolve the version, disallowing cases like: # #version 120 This patch also adds the above shaders as new glcpp tests. Fixes dEQP-GLES2.functional.shaders.preprocessor.predefined_macros. {gl_es_1_vertex,gl_es_1_fragment}.

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.
