配置log4cpp时的^A & ^B字符

Question

当我试图配置从位置log4cpp克隆的Log4cpp CodeGit时。

我在#ifdef宏的末尾观察到^A & ^B字符，因为它没有编译。

我遵循的步骤是

1) git克隆git://git.code.sf.net/p/log4cpp/codegit log4cpp-codegit

2) /autogen.sh

3) ./配置

输出文件的摘录包括/log4cpp/config.h

* Define to 1 if you have the <dlfcn.h> header file. */
#ifndef LOG4CPP_^A 
#define LOG4CPP_^A ^B 
#endif

/* Define to 1 if you have the `ftime' function. */
#ifndef LOG4CPP_^A 
#define LOG4CPP_^A ^B 
#endif

如果有人面临这个问题并解决了问题，请告诉我。

谢谢。

抱歉，问题出在我使用的autoconf的错误版本上。
