問題我想將我的python模塊嵌入到我的c代碼中，然後從那裏我想從C++應用程序運行它。出於某種原因，我無法在每次運行它時崩潰。我設置我的PYTHONPATH以及加載在調試python符號和編譯爲c + +即使我沒有得到任何錯誤，我的應用程序只是不想開始。任何幫助都將不勝感激！將Python嵌入到c中，然後在一個不工作的C++程序中運行它
這裏是Python文件tobase34.py
class SnowBaseConvert(object):
#def __init__(self, innitvar, basevar, convertvar):
# self.innitvar = innitvar
# self.basevar = basevar
# self.convertvar = convertvar

integer = 0
for character in innitvar:

#SnowBaseConvert().main('056866536', 10, 34)
這裏是我的C文件base34conv.c
#include "base34conv.h"
char * convertbase34(){
//Py_SetPythonHome("C:\\Python27");
Py_Initialize();
PyObject* module = PyImport_ImportModule("tobase34");
assert(module != NULL);
PyObject* klass = PyObject_GetAttrString(module, "SnowBaseConvert");
assert(klass != NULL);
PyObject* instance = PyInstance_New(klass, NULL, NULL);
assert(instance != NULL);
PyObject* result = PyObject_CallMethod(instance, "main", "(sii)", "056866536", 10, 34);
assert(result != NULL);
Py_Finalize();
return PyString_AsString(result);
}
這是我實現文件base34conv.h
#include <string.h>
#include <assert.h>
#include <stdio.h>
#include <stdlib.h>
#include <assert.h>
#pragma comment(lib, "C:\\Python27\\libs\\python27.lib")
#ifdef _DEBUG
#undef _DEBUG
#include "C:\\Python27\\include\\Python.h"
#define _DEBUG
#else
#include "C:\\Python27\\include\\Python.h"
#endif
#ifdef __cplusplus
extern "C" {
#endif
char * convertbase34();
#ifdef __cplusplus
}
#endif
而終於這裏是我的C++文件它的勝利形式應用程序

你有沒有試圖以任何方式自己調試它？隔離失敗的行，添加日誌記錄，可能使用調試器，什麼？你甚至不知道代碼在哪一行失敗。 – user2357112
