我正在尝试在C程序中调用cython(cdef)函数。当cdef函数包含python语句(例如print(0.5)或python(def)函数)时,调用(cdef)函数会引发分段错误。
.pyx文件:
# cython: language_level=3
cdef public double PI = 3.1415926
cdef public double get_e():
print("calling get_e()")
return 2.718281828

int main(int argc, char **argv) {
Py_Initialize();
PyInit_transcendentals();
printf("pi**e: %f\n", pow(PI, get_e()));
Py_Finalize();
return 0;
