python - C++ Python 解释器 - Py_Initialize 崩溃

Question

我已经编译了 32 位的 python 源代码，并尝试使用 Py_Initialize() API 在我的 C++ 应用程序中初始化 python 解释器。
Py_Initialize() 导致以下崩溃。请帮我解决这个问题。

正在编译我的代码如下:

g++ ./Pythoninterpreter.cpp -m32 -lpthread -ldl -lutil /usr/lib/libm.a /usr/lib/libpython2.7.a -Xlinker -export-dynamic -I/root/python_tar/Python-2.7.6/Include -I/root/python_tar/Python-2.7.6 -o pythonintepreter

我不完全确定你想做什么，因为你没有在 PythonInterpreter.cpp 上提供代码。

以下代码使用命令行编译:

g++ -I/usr/include/python2.7/-o foo foo.cpp -lpython2.7

#include  "Python.h"
int main()
{
  Py_Initialize();
  return 0;
}
