This uses the Mesa disk_cache support to write out the final linked
binary for vertex and fragment shader programs.
This is based off the initial implementation done by Carl Worth. It
has been significantly reworked, first by Tim Arceri, and then by
Jordan Justen.
v2:
* Squash 'i965: add image param shader cache support'
* Squash 'i965: add shader cache support for pull param pointers'
* Sustantially simplified by a rework on top of Jason's 2975e4c56a.
* Rename load_program_data to read_program_data. (Jason)
v3:
* Simplify and align program read/write. (Jason)
v4:
* Don't save prog_data size since we know it from the stage. (Ken)
* Don't save program size, since prog_data includes the size. (Ken)
* Remove `assert` that potentially could be triggered by disk
corruption of the cache entries. (Ken)
* Fix compute shader scratch allocation. (Ken)
* Remove special case mapping for non-LLC. (Ken)
* Remove SET_UPLOAD_PARAMS macro

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 https://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.
