为Windows7构建台面。台面9.1

Question

我浏览了Mesa网站编译/安装页面上的所有步骤，并阅读了FAQ。发送给scons进行编译的最后一个命令在python脚本中抛出错误。这是我的输出。我做错什么了？另外，如果有人使用最新的mesa和mingw或VS2012为mesa编译了dll，请共享！

这是我的输出，我很久没有编写python了，但是似乎map/dictionary不包含键/值对。

常用选项：

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

1. Linux（Debian喘息），toolchain=crossmingw：在链接阶段失败，因为它找不到__vscprintf等等。从Debian Jessie 8.5&Mesa开始工作d2f42a945ec0fbcc51b59cfd329258bd62ebf0d2：

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

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

2. Windows，toolchain=mingw：失败，原因是“命令行太长”。尽管两个snippits在^{}上都有多个排列。

3. 从src/glsl/ralloc.c::ralloc_size()中删除stray C99-isms后，MSVC_VERSION=11.0：成功。

编辑：更完整的过程：

1. 安装Visual Studio Express 2012 for Windows桌面：

   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Python2.7：

   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. 为Python安装libxml2：

   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PATH顶部附近：

   C:\Python27\
   C:\Python27\Scripts
   

8. 下载Mesa：

   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外壳：

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

10. 构建台面：

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

这将在build\windows-x86\gallium\targets\libgl-gdi中创建opengl32.dll。

使用little bit more legwork可以构建llvmpipe。
