skippin＆＃39; cutilFunctions.c＆＃39; Cython扩展（最新）

Question

我正在尝试从https://github.com/MTG/sms-tools/blob/master/README.md

编译文件

我遇到错误的文件代码行是：python compileModule.py build_ext --inplace

当我这样做时：PS C：\ sms-tools-master \ software \ models \ utilFunctions_C＆gt; python compileModule.py build_ext --inplace

我有这个：

非常感谢你的帮助。我很长时间以来一直在托管这个问题。

这个问题也在这里得到解决： Problems with compiling C code in Python

解决方案是通过排除compileModule.py库来更改m;

setup(
cmdclass = {'build_ext': build_ext},
#ext_modules = [Extension("utilFunctions_C",sourcefiles, libraries=['m'], include_dirs=py_inc + np_inc)]
ext_modules = [Extension("utilFunctions_C",sourcefiles , include_dirs=py_inc + np_inc)]
)
