Question

我有一个非常简单的cython代码，它是用python3构建的

python3 setup.py build_ext

cpdef public int say_hello ():
    print("HELLO")
    return 1

我在C程序中调用的

#include <Python.h>

Py_Initialize();
PyInit_libwrapper();
int ok = say_hello();

这是我得到的错误

#0  0x00007fffeabebb52 in PyTuple_Pack () at /usr/lib/x86_64-linux-gnu/libpython3.6m.so.1.0
#1  0x00007fffea7eb8f1 in __Pyx_PrintOne (stream=0x0, o=<optimized out>) at code/cython/wrapper.c:2123
#2  0x00007fffea7eb8f1 in say_hello (__pyx_skip_dispatch=<optimized out>) at code/cython/wrapper.c:1114

如果我不调用print函数，一切都会很好，而且如果我使用python2（如下），一切都会很好

python2 setup.py build_ext

#include <python2.7/Python.h>

Py_Initialize();
initlibwrapper();
int ok = say_hello();

哪里出问题了？

我遇到了另一个错误

say_hello (__pyx_skip_dispatch=0) at code/cython/wrapper.c:1106
1106      __pyx_t_1 = __Pyx_PyObject_Call(__pyx_builtin_print, __pyx_tuple_, NULL); if (unlikely(!__pyx_t_1)) __PYX_ERR(0, 21, __pyx_L1_error)
(gdb) bt
#0  0x00007fffea7eb8cc in say_hello (__pyx_skip_dispatch=0) at code/cython/wrapper.c:1106

Cython崩溃，调用打印功能
