构建Mesa for windows 7. Mesa 9.1

Question

我在Mesa网站的编译/安装页面上完成了所有步骤,并阅读了常见问题解答.您发送给scons进行编译的最终命令会在python脚本中引发错误.这是我的输出.我究竟做错了什么？如果有人使用最新的台面和mingw或VS2012编译了dsa用于台面,那么请分享!

这是我的输出,我没有在很长一段时间内编写python,但看起来地图/字典不包含键/值对.

常见scons选项:

build=release
machine=x86
platform=windows
libgl-gdi

1. Linux(Debian Wheezy)toolchain=crossmingw:在链接阶段失败,因为__vscprintf除其他外,它找不到. 作为Debian Jessie 8.5和Mesa的作品d2f42a945ec0fbcc51b59cfd329258bd62ebf0d2:

   scons \
   toolchain=crossmingw \
   build=release \
   machine=x86 \
   platform=windows \
   libgl-gdi
   

   DLL已安装到 build/windows-x86/gallium/targets/libgl-gdi/opengl32.dll

2. Windows的toolchain=mingw:失败与"命令行太长." 尽管两个snippits的多个排列LongCmdLinesOnWin32.

3. Windows中,VS2012快递,MSVC_VERSION=11.0:则成功移除之后杂散C99-主义的src/glsl/ralloc.c::ralloc_size().

编辑:更完整的程序:

1. 安装适用于Windows桌面的Visual Studio Express 2012:

   http://www.microsoft.com/visualstudio/eng/downloads#d-express-windows-desktop
   

2. 安装MinGW:

   http://www.mingw.org/
   http://sourceforge.net/projects/mingw/files/
   http://sourceforge.net/projects/mingw/files/latest/download?source=files
   mingw-get-inst-20120426.exe
   
   Run installer:
   Download latest repo catalogs
   Install to C:\MinGW (default)
   Check:
   * C compiler
   * C++ compiler
   * MSYS basic system
   * MinGW developer toolkit (should install msys-flex and msys-bison)
   

3. 安装Python 2.7:

   http://www.python.org/download/
   http://www.python.org/ftp/python/2.7.5/python-2.7.5.msi
   
   You have to use 32-bit Python because the Scons people only distribute 32-bit installers.
   
   Install for all users (default)
   Install to C:\Python27 (default)
   Use default install options/customizations
   

4. 安装libxml2Python:

   http://www.lfd.uci.edu/~gohlke/pythonlibs/
   libxml2-python-2.9.1.win32-py2.7.?exe
   
   Installer should find the python install automagically
   

5. 安装pywin32:

   http://pywin32.sourceforge.net/
   http://sourceforge.net/projects/pywin32/files/pywin32/
   http://sourceforge.net/projects/pywin32/files/pywin32/Build%20218/
   http://sourceforge.net/projects/pywin32/files/pywin32/Build%20218/pywin32-218.win32-py2.7.exe
   
   Installer should find the Python install automagically
   

6. 安装Scons:

   http://www.scons.org/
   http://prdownloads.sourceforge.net/scons/scons-2.3.0-setup.exe
   
   Installer should find the Python install automagically
   

7. 将这些添加到您的顶部附近PATH:

   C:\Python27\
   C:\Python27\Scripts
   

8. 下载梅萨:

   ftp://ftp.freedesktop.org/pub/mesa/
   ftp://ftp.freedesktop.org/pub/mesa/9.1.5/MesaLib-9.1.5.zip
   
   Extract somewhere (C:\Mesa-9.1.5)
   

9. 启动MSYS shell:

   C:\mingw\msys\1.0\msys.bat
   
   Change into mesa src directory:
   cd /c/Mesa-9.1.5/
   

10. 建立梅萨:

    scons.py \
    build=release \
    machine=x86 \
    platform=windows \
    MSVC_VERSION=11.0 \
    libgl-gdi \
    

这应该创建一个opengl32.dll在build\windows-x86\gallium\targets\libgl-gdi.

通过更多的腿部工作,可以构建llvmpipe.
