Qt Signal Slot Undefined Reference
2021年6月24日Register here: http://gg.gg/v49sr
When you are going to use Qt signals & slots mechanism you have to add QOBJECT macro in the top of definition of your class in order to generate correct moc code. The Meta-Object Compiler, moc, is the program that handles Qt’s C extensions. The moc tool reads a C header file. I have a Qt Creator project (qmake, Qt 5.2.0, Creator 3.0.0) that uses the subdirs template. There are three subprojects: Stadium - library that is configured as TEMPLATE = lib and CONFIG += staticlib.; Football - library that is configured as TEMPLATE = lib and CONFIG += staticlib and uses the Field library.; Server - a QML application that uses both Stadium and Football libraries. QObjectから継承した後のQt ’signal undefined reference error’ 7 最近クラスに信号を追加する必要があったので、QObjectから継承するようにクラスを変更し、QOBJECTマクロをクラス定義に追加しました。.

Apart from whatever is mentioned in this answer, also make sure to run qmake. i.e.:
That should fix these errors.
I have a class server for which I have created a signal joined(QString name). I call it in a function called join(QString name), however I’m getting the errorQt Signal And Slots
Server.o: In function Server::join(QString)’: Server.cpp:(.text+0x48): undefined reference to Server::joined(QString)’ collect2: ld returned 1 exit status
This is what my header file looks like:Qt Connect Signal Slot

At the beginning of your class declaration you should have the macro Q_OBJECT and be sure to inherit from some QObject descendant.
