python - 为 Windows 7 构建 Mesa。Mesa 9.1

Question

我完成了 Mesa 网站上编译/安装页面上的所有步骤，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 脚本中抛出错误。这是我的输出。我究竟做错了什么？此外，如果有人使用最新的 mesa 和 mingw 或 VS2012 为 mesa 编译了 dll，请分享!

这是我的输出，我已经很长时间没有编写 python 程序了，但 map /字典似乎不包含键/值对。

常用scons选项:

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

1. Linux (Debian Wheezy)，toolchain=crossmingw:链接阶段失败，因为找不到__vscprintf，除其他事项外。 工作自 Debian Jessie 8.5 和 Mesa d2f42a945ec0fbcc51b59cfd329258bd62ebf0d2 通过:

   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“命令行太长”。尽管在 LongCmdLinesOnWin32 上对两个片段进行了多次排列.

3. Windows、VS2012 Express、MSVC_VERSION=11.0:删除 stray C99-isms 后成功来自 src/glsl/ralloc.c::ralloc_size()。

编辑:更完整的程序:

1. 为 Windows 桌面安装 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. 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 的顶部附近:

   C:\Python27\
   C:\Python27\Scripts
   

8. 下载台面:

   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 \
    

这应该在 build\windows-x86\gallium\targets\libgl-gdi 中创建一个 opengl32.dll。

用little bit more legwork可以构建 llvmpipe。
