第一步,下载glog-0.3.3.tar.gz,解压,直接打开google-glog.sln工程文件,如果vs版本不对,让其自动转换
第二步,编译,在Debug下生成libglog.dll、 libglog.lib、libglog_static.lib
第三步,将头文件和lib库拷贝到自己的工程下,由于我暂时是window下使用,头文件使用 \glog-0.3.3\src\windows\glog
第四步,引用到自己工程下,编译发现报错:
- 1>d:\workspace\video\videomanage\devicemgr\lib\glog\glog\log_severity.h(55): fatal error C1189: #error : ERROR macro is defined. Define GLOG_NO_ABBREVIATED_SEVERITIES before including logging.h. See the document for detail.
- 1> SessionMgr.cpp

- 1> SessionFactory.cpp

- 1>d:\workspace\video\videomanage\devicemgr\lib\glog\glog\log_severity.h(55): fatal error C1189: #error : ERROR macro is defined. Define GLOG_NO_ABBREVIATED_SEVERITIES before including logging.h. See the document for detail.
- 1> CatalogSesssion.cpp
- 1>d:\workspace\video\videomanage\devicemgr\lib\glog\glog\log_severity.h(55): fatal error C1189: #error : ERROR macro is defined. Define GLOG_NO_ABBREVIATED_SEVERITIES before including logging.h. See the document for detail.
进入log_severity.h头文件查看,是一个宏定义的地方出现了冲突:
- #ifndef GLOG_NO_ABBREVIATED_SEVERITIES
- # ifdef ERROR
- # error ERROR macro is defined. Define GLOG_NO_ABBREVIATED_SEVERITIES before including logging.h. See the document for detail.
- # endif
- const int INFO = GLOG_INFO, WARNING = GLOG_WARNING,
- ERROR = GLOG_ERROR, FATAL = GLOG_FATAL;
- #endif
解决方法:
在工程加上预编译宏GLOG_NO_ABBREVIATED_SEVERITIES
C/C++ --> 预处理器 --> 预处理器定义 --> 加上GLOG_NO_ABBREVIATED_SEVERITIES宏 保存,编译通过~
第五步,自己的项目中使用
- #include "glog/logging.h"
- int _tmain(int argc, _TCHAR* argv[])
- {
- google::InitGoogleLogging((const char *)argv[0]); //参数为自己的可执行文件名
- google::SetLogDestination(google::GLOG_INFO,"./myInfo");
- LOG(INFO) << "This is a <Warn> log message..." << ;
- .....................
- }
搞定,后面就是将这些日志在工程中使用起来了。
