Previously, if the preprocessor encountered a #define with a non-identifier, such as: #define 123 456 The lexer had no explicit rules to match non-identifiers in the <DEFINE> start state. Because of this, flex's default rule was being invoked, (printing characters to stdout), and all text was being discarded by the compiler until the next identifier. As one can imagine, this led to all sorts of interesting and surprising results. Fix this by adding an explicit rule complementing the existing identifier-based rules that should catch all non-identifiers after #define and reliably give a well-formatted error message. A new test is added to "make check" to ensure this bug stays fixed. This commit also fixes the following Khronos GLES3 CTS test: define_non_identifier_vertex (The "fragment" variant was passing earlier only because the preprocessor was behaving so randomly and causing the compilation to fail. It's lucky, in fact, that the "vertex" version succesfully compiled so we could find and fix this bug.) Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> |

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 osmesa mesagdi to build classic mesa Windows GDI drivers; or 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.
