The builtin_compiler binary is used during the build process to generate code for the builtin GLSL functions. Since this binary needs to be run on the build host, it must not be cross-compiled. This patch fixes the build system to compile a second version of the source files and the builtin_compiler binary itself for the build system. It does so by defining the CC_FOR_BUILD and CXX_FOR_BUILD variables, which are searched for by the configure script and point to the location of native C and C++ compilers. In order for this to work properly, builtin_function.cpp is removed from BUILT_SOURCES, otherwise the build system would try to generate it before having had a chance to descend into the builtin_compiler subdirectory. With the builtin_compiler and glsl_compiler now being generated at different stages, the build instructions for glsl_compiler can be simplified a bit.

File: docs/README.WIN32 Last updated: 23 April 2011 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. 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.
