Compiling and using Cython C file independently

[Shuangyi Li]

Dear cythoners,

I am wondering how to compile and use cython .c file indepently, not in python.

as far as I know, in general, people use cython to get .pyd file and import them in other .py file to get speed improved. But now I want use the output .C file independently, not in a python enviroment.

So far, I have tried to directly use GCC to compile .C files obtained through cython. 

The command is:

gcc hello.c -L C:......\Python\Python310\libs\python310.lib -fPIC -DMS_WIN64

The error prompt is:

undefined reference to `__imp_PyType_IsSubtype'

undefined reference to `__imp__Py_Dealloc'

undefined reference to `__imp_PyModuleDef_Init'

and so many similar errors.

I think this is a problem with the .lib file, but I don't know whether I connected the .lib file in the wrong way or I connected the wrong lib file. Does anyone have any suggestions? What should I do?

Thanks to all

The generated .c file depends on the Python C API, and needs to be
linked against the Python libraries to work.

You can, however, implement utilities in Cython and invoke them from
other .c files. See
