1. 在vs2005中编译python_pjsua项目会有下列错误（python2.7）
Creating library ./output/python_pjsua-i386-win32-vc8-debug/_pjsua_d.lib and object ./output/python_pjsua-i386-win32-vc8-debug/_pjsua_d.exp

主要是因为 Py_DEBUG/Py_TRACE_REFS 引起, 可以修改 Python/include 下的 pyconfig.h, object.h 两个文件。原来有个链接但好像打不开。具体修改如下：
1. 修改 pyconfig.h
修改
#ifdef _DEBUG
# define Py_DEBUG
#endif
为
#ifdef _DEBUG
//# define Py_DEBUG
#endif
修改
# ifdef _DEBUG
# pragma comment(lib,"python24_d.lib")
# else
# pragma comment(lib,"python24.lib")
# endif /* _DEBUG */
为
# ifdef _DEBUG
# pragma comment(lib,"python24.lib")
# else
# pragma comment(lib,"python24.lib")
# endif /* _DEBUG */
2. object.h
修改
#if defined(Py_DEBUG) && !defined(Py_TRACE_REFS)
#define Py_TRACE_REFS
#endif
为
#if defined(Py_DEBUG) && !defined(Py_TRACE_REFS)
// #define Py_TRACE_REFS
#endif
但主要也是在Debug模式下出问题，可以选为release版的
