I am trying to use mqtt protocol in qt quick application. i have already followed the steps which are explained in Qt Documentation Quick MQTT Example. i am getting error while building "error : "Unknown module(s) in Qt : mqtt". How to solve this?

Thanks!

@arbaj-patel it looks like you need to build the Qt MQTT module first.

Hi @Arbaj-Patel,

You can install follow these commands:
/home/nexle-user/Qt5.13.1/5.13.1/gcc_64/bin/qmake -query QT_INSTALL_LIBS (here I build mqtt for desktop so I use qmake inside gcc_64, if you want to build for other platform, just choose correct qmake ) . And this is my output /home/nexle-user/Qt5.13.1/5.13.1/gcc_64/lib, then cd to there:
cd /home/nexle-user/Qt5.13.1/5.13.1/gcc_64/lib
git clone git://code.qt.io/qt/qtmqtt.git
cd qtmqtt
/home/nexle-user/Qt5.13.1/5.13.1/gcc_64/bin/qmake
make
make install (if has errors, please try sudo make install )
Thank you.
