可以更改 distutils 默认编译器选项吗？

Question

Win 10、x64、minGW64、Python2.7、Anaconda

我正在尝试使用 python setup.py build --compiler=mingw32

编译 zbar 以便在 Python 2.7 中使用

这里是setup.py

from distutils.core import setup, Extension
from distutils.sysconfig import get_config_vars
setup(
    name = 'zbar',
    version = '0.10',
    author = 'Jeff Brown',
    author_email = 'spadix@users.sourceforge.net',
    url = 'http://zbar.sourceforge.net',
    description = 'read barcodes from images or video',
    license = 'LGPL',
    long_description = open('README').read(),
    classifiers = [
        'License :: OSI Approved :: GNU Library or Lesser General Public License (LGPL)',
        'Development Status :: 4 - Beta',
        'Intended Audience :: Developers',
        'Environment :: Console',
        'Environment :: X11 Applications',
        'Environment :: Win32 (MS Windows)',
        'Operating System :: POSIX',
        'Operating System :: Unix',
        'Operating System :: Microsoft :: Windows',
        'Topic :: Communications',
        'Topic :: Multimedia :: Graphics',
        'Topic :: Software Development :: Libraries',
    ],
    ext_modules = [
        Extension('zbar', [
                'zbarmodule.c',
                'enum.c',
                'exception.c',
                'symbol.c',
                'symbolset.c',
                'symboliter.c',
                'image.c',
                'processor.c',
                'imagescanner.c',
                'decoder.c',
                'scanner.c',
                ],
            libraries = [ 'zbar' ],
            library_dirs=["""C:\Program Files (x86)\ZBar\lib"""],
            include_dirs=[get_config_vars('INCLUDEDIR'),
                              get_config_vars('INCLUDEPY'),
                             """C:\Program Files (x86)\ZBar\include"""]
        ),
    ],
)

但我不断收到以下错误...

running build
running build_ext
building 'zbar' extension
C:\Program Files\mingw-w64\x86_64-8.1.0-win32-seh-rt_v6-rev0\mingw64\bin\gcc.exe -mno-cygwin -mdll -O -Wall -DMS_WIN64 -I[None] -I['C:\ProgramData\Anaconda2\include'] "-IC:\Program Files (x86)\ZBar\include" -IC:\ProgramData\Anaconda2\include -IC:\ProgramData\Anaconda2\PC -c zbarmodule.c -o build\temp.win-amd64-2.7\Release\zbarmodule.o
gcc: error: unrecognized command line option '-mno-cygwin'; did you mean '-mno-clwb'?
error: command 'C:\Program Files\mingw-w64\x86_64-8.1.0-win32-seh-rt_v6-rev0\mingw64\bin\gcc.exe' failed with exit status 1

由此看来“-mno-cywin”不再是有效的编译选项，因此出现错误。

我发现 this post 关于 distutils Mac OS X 10.8.3 的编译器选项并在某处找到 distutils 正在从中读取一些默认标志原始 Python 安装，但我 none 更了解如何更改它们。

如何在 Windows 10 机器上更改传递给 distutils 的编译器选项，Anaconda 发行版为 Python，即缺少 disutils.cfg？

是否可以自己编写distutils.cfg？

Answer 1

选项在distutils/cygwinccompiler.py中。如果您可以在 Python 安装中编辑该文件，请将其删除。
