Log4Qt - Logging for the Qt cross-platform application framework

Continuous Integration

Travis CI (Linux)

Appveyor CI (Windows)

Description

Log4Qt is a C++ port of the Apache Software Foundation Log4j package using the Qt Framework. It is intended to be used by open source and commercial Qt projects.

Original project

http://log4qt.sourceforge.net/

This Log4Qt repository is a clone of the Log4Qt repository from https://gitorious.org/log4qt which was itself a clone of the original Log4Qt project on SourceForge http://sourceforge.net/projects/log4qt/ (http://log4qt.sourceforge.net/).

Additional features

• SimpleTimeLayout (“dd.MM.yyyy hh:mm [Thread] Level Logger Message”)
• ColorConsoleAppender (render colorized message by escape sequence and put it to console)
• SignalAppender (emit signal when log event happens)
• DatabaseAppender (append log event into sql table)
• DatabaseLayout (put log event into sql table columns)
• Telnet appender (append log event to telnet clients)
• LogStream (qDebug()-style log messages appending)
• MainThreadAppender (Proxy appender for sending log messages through event loop)
• XMLLayout to support apache chainsaw
• DailyFileAppender which generates a logfile for each day (add current date formatted to the filename)
• Binary logger
• Windows Debug Console Appender

Requirements

• Minimum Qt version required Qt5.7 (for support of Qt versions down to 5.3 use branch 1.4 or the lates 1.4.x release)
• C++11 feature required (minimum compiler version MSVC14, GCC 4.8 or CLANG 3.3)

Build and install

qmake

use qmake to build the project

*NIX
    qmake
    make
    make install

WIN* (mingw)
    qmake
    mingw32-make
    mingw32-make install

WIN* (msvc)
    qmake
    msbuild Log4Qt.sln
    msbuild /t:INSTALL Log4Qt.sln

For static build call qmake with
qmake "DEFINES+=LOG4QT_STATIC" or uncommend LOG4QT_STATIC in the build.pri file
Don't forget to define LOG4QT_STATIC also in your project.

Logging to a database via databaseappender can be enabled with qmake "QT += sql"

include in your project

Can also be used by adding the log4qt source directly to your Qt project file by adding the following line: include(/src/log4qt/log4qt.pri)

cmake

cmake is the second option to build Log4Qt. An out-of-source build is required: <unpack/fetch to Log4Qt directory> mkdir Log4Qt-build cd Log4Qt-build cmake ../Log4Qt make/mingw32-make/msbuild Log4Qt.sln (same as with qmake) make/mingw32-make install or: msbuild /t:INSTALL Log4Qt.sln

Addition cmake options are
    * '-DBUILD_STATIC_LOG4CXX_LIB=ON|OFF' to build static log4qt lib (default: OFF)
    * '-DBUILD_WITH_DB_LOGGING=ON|OFF' to build with database logging support
