}

float add_float(float num1, float num2) {

}

int print()
{
 printf("test print");
 return 1;

makefile 使用 windows 下的gcc（minGW TDM-GCC-64）

gcc -c sample.c
gcc -shared -o sample.dll sample.o -Wl,--out-implib,libsample.a

test.py

from ctypes import *
from ctypes.util import find_library

if __name__ == '__main__':
 adder = cdll.LoadLibrary('./add.dll')
 model = adder.add_int
 num = model(1,2)
 print(num)
 adder.main()
