Win 10, x64, minGW64, Python 2.7, Anaconda
I am trying to compile zbar for use in Python 2.7 using python setup.py build --compiler=mingw32
Here's 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 = '[email protected]',
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',

'Operating System :: POSIX',

],
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"""]
),
],
)
But I keep getting the following error...
running build
running build_ext
building 'zbar' extension

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
From this post it appears that '-mno-cywin' is no longer a valid compilation option hence the error.
I found this post about distutils compiler options for Mac OS X 10.8.3 & get that somewhere distutils is reading some default flags from the oringal Python install but I'm none the wiser about how to change them.
How do I change the compiler options passed to distutils on a Windows 10 machine with an Anaconda distribution of Python ie with disutils.cfg missing?
Is it possible to write my own distutils.cfg?
The option is in distutils/cygwinccompiler.py. If you can edit the file in the Python installation just remove it.
