log4cplus的各种坑

前言

项目中需要用到这个日志管理工具，新人，新电脑，之前的项目程序在我的电脑上都跑不起来。一直爆出C000000005的那个错误。大牛指点之后发现是我电脑上不能用这个日志系统，具体为什么不能用她也没说，所以姐姐我就自己安装下这个工具来试看看，结果各种坑啊。

安装

编译失败

① error C3861: 'LOG4CPLUS_WARN': identifier not found

添加文件头：

#include <log4cplus/loggingmacros.h>

② error LNK2019: 无法解析的外部符号 "const log4cplus::Appender::`vbtable'" (??_8Appender@log4cplus@@7B@)，该符号在函数 "public: void __thiscall log4cplus::Appender::__autoclassinit(unsigned int)" (?__autoclassinit@Appender@log4cplus@@QAEXI@Z) 中被引用

参考

解决方法:添加于处理器定义 LOG4CPLUS_BUILD_DLL

还是不对

什么鬼根本不对，不是添加那个处理器的定义

这样子应该是对了吧

出来结果的时候姐姐都感动哭了
