The upcoming shader cache needs this to be able to cache hash data from the gl_shader_program structure. Edited-by: Carl Worth <cworth@cworth.org>: There is an internal implementation detail that the hash table underlying the struct string_to_uint_map stores each value internally as (value+1). The user needn't be very concerned with this (other than knowing that a value of UINT_MAX cannot be stored) since put() adds 1 and get() subtracts 1. So in this commit, rather than call the user's function directly with hash_table_call_foreach, we call through a wrapper that fixes up the off-by-one values before the caller's callback sees them. And with this wrapper in place, we also give a better signature to the callback function being passed to iterate(), so that this callback function can actually expect a char* and an unsigned argument, (rather than a couple of void* ).

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.
