    Question Mesa3d installing for Windows 10

    Hello,

    I don't understand the installing guide from Mesa 3d (Homepage from Mesa 3d)
    I have already downloaded Mesa 13.02, Python 2.7.12 and SCons 2.5.1.

    Thanks for request !

    Your best bet for help building/installing on Windows is probably the Mesa3D mesa-users mailing list:

    * http://www.mesa3d.org/lists.html

    You might even find someone that will share some precompiled binaries so you can just skip building and go straight to using Mesa3D. However, I see that they're recommending you try here first :-)

    Which part are you having trouble with?:

    I have also this problem.

    I think he don't understand like me what they me with that installing guide:



    To build Mesa with SCons on Linux or Windows do

    scons
    The build output will be placed in build/platform-machine-debug/..., where platform is for example linux or windows, machine is x86 or x86_64, optionally followed by -debug for debug builds.

    To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do

    scons platform=windows toolchain=crossmingw machine=x86 libgl-gdi
    This will create:

    build/windows-x86-debug/gallium/targets/libgl-gdi/opengl32.dll Mesa + Gallium + softpipe (or llvmpipe), binary compatible with Windows's opengl32.dll
    Put them all in the same directory to test them.

    Search opengl32.dll file with full OpenGl 3.3 support and no buying

    The best would be, if you let me download a opengl32.dll file with full OpenGl 3.3 support.
    That is the thing I need for my Windows 10 PC.
    --> I don't want to buy a new graphic card.


    Thanks !

    OpenGL doesn't work that way. OpenGL is not software.

    If you want hardware accelerated graphics then you must use the driver for your graphics card. If the driver for your graphics card does not support a particular GL version then you cannot have it hardware accelerated. This isn't about letting you do it or preventing you from doing it. It just does not work that way.

    Mesa is a software implementation. It is not a good alternative if you want performance. You will be disappointed.

    I need Mesa for a programm which need OpenGl 3.3.
    So I will be happy with Mesa although it's not the best support.

    Mesa3D on Windows

    A better guide to build mesa was written by some folks at QT. They posted it on their Wiki.
    I took that guide and automated the process. I went so far that I created a complete installer.
    It installs mesa3d system-wide and also an utility for local deployments as certain applications may be confused.
