跳过'cutilFunctions.c‘Cython扩展(最新)

Question

我正在尝试从：https://github.com/MTG/sms-tools/blob/master/README.md编译一个文件

出现错误的文件代码行是: python compileModule.py build_ext --inplace

当我这样做的时候: PS C:\sms-tools-master\software\models\utilFunctions_C> python compileModule.py build_ext --就地

我有这个：

非常感谢您的帮助。我已经花了很长时间来解决这个问题。

这里也解决了这个问题：Problems with compiling C code in Python

解决方案是通过排除m库来修改compileModule.py；

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)]
)
