直接下载这个tag的版本。编译时如果出现错误，共4处，serial的注掉，light改为lighter, dark改为darker。也可能是正常的，没有错误。

https://github.com/MEONMedical/Log4Qt/releases/tag/v1.5.1

 注意：master分支代码并不支持文件名与行号打印。

============================================

qt工程引入 ：

include(Log4Qt/src/log4qt/log4qt.pri)

include(Log4Qt/build.pri)

include(Log4Qt/g++.pri)

QT += concurrent

DEFINES += LOG4QT_LIBRARY

DEFINES += LOG4QT_EXPORT

DEFINES += QT_MESSAGELOGCONTEXT

INCLUDEPATH += Log4Qt/src/

INCLUDEPATH += Log4Qt/src/log4qt

DEPENDPATH += Log4Qt/src/log4qt

 

 上面的红色必须要加，否则也会有问题

=============================================

测试：

#include <QCoreApplication>

#include "log4qt/logger.h"

#include "log4qt/basicconfigurator.h"

#include "log4qt/propertyconfigurator.h"

#include "log4qt/logmanager.h"

#include "QDebug"

using namespace std;

using namespace Log4Qt;

int main(int argc, char *argv[])

{

    QCoreApplication a(argc, argv);

    PropertyConfigurator::configureAndWatch("D:\\qtworkspace\\test_log4qt_for_function\\log4qt.properties");

    LogManager::setHandleQtMessages(true);

    qDebug()<<"radar display begins to boot up ."<<endl;  //只有这种打日志的方式可以输出文件名，函数名与行号

    qDebug("hello world!");

    return a.exec();
}


最后这种能够输出文件名，行号，函数名的原因是他们已经自带国这些信息。
