导读：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

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-0.3.3srcwindowsglog 第四步，引用到自己工程下，编译发现报错： 1>d:workspacevideovideomanagedevicemgrlibgloggloglog_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>d:workspacevideovideomanagedevicemgrlibgloggloglog_severity.h(55): fatal error C1189: #error : ERROR macro is defined.

See the document for detail. 1> SessionFactory.cpp 1>d:workspacevideovideomanagedevicemgrlibgloggloglog_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..." << ; ..................... }  （编辑：我爱故事小小网_铜陵站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
