At the moment to get an EGL image to a dma-buf file descriptor, you have to use EGL_MESA_drm_image, and then use libdrm to convert this to a file descriptor. This extension just provides an API modelled on EGL_MESA_drm_image, to return a dma-buf file descriptor. v2: update spec for new API proposal add internal queries to get the fourcc back from intel driver. v2.1: add gallium pieces. v2.2: add offsets to spec and API, rename fd->fds, stride->strides in API. rewrite spec a bit more, add some q/a v2.3: add modifiers to query interface and 64-bit type for that (Daniel Stone) specifiy what happens to num fds vs num planes differences. (Chad Versace) v2.4: fix grammar (Daniel Stone) Signed-off-by: Dave Airlie <airlied@redhat.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 to build classic osmesa driver; 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.
