    Thank you for reply my question.
    Is there any way to using it in QT ? because I see it has been added with the other QT module.

      Hi
      is github.com/emqtt a true Qt module ?
      Looks to me as just an normal c++ lib/so/dll ?

      To use such lib, one would just tell Creator via the .pro file
      http://doc.qt.io/qt-5/third-party-libraries.html
      Key points being

      INCLUDEPATH += xxxxxx/include
      LIBS += -L"xxxx/lib" -lqtmqtt

      The page do not seems to call it a module but I could be wrong.

        You should load it or bind it to your project like @mrjj said.

        btw. qtmqtt repository: I had some issues on building. After fixing that it worked - but is really in a early state. There is no support for proxy - so if you are behind a company proxy, there is no way to use the official MQTT client. Also the broker is just in work and not working yet.
        Hope they will continue work on here, because I want to use a official module...

            @alphaT Just create all these directories put the files there and edit your pro file to point to the files. Like:

            SOURCES += src/main.cpp

                @alphaT You can do it with any file manager on in a terminal

                  Thank all of you for your help.

                  INCLUDEPATH += ~/qmqtt/src/mqtt
                  LIBS += -L"~/qmqtt/src/mqtt" -lqmqtt

                  I just add two line to .pro file like you say above, and it works.

                    If you want the Qt Mqtt module that Qt Company is developing, that is here:
                    http://code.qt.io/cgit/qt/qtmqtt.git/

                    You need to clone: git://code.qt.io/qt/qtmqtt.git

                    This does install a module called 'mqtt'

                              @alphaT It looks like you're building with Qt which is delivered by your Linux distribution (/usr/include/qt5).
                              I guess you simply called qmake from command line, right?
                              You should use complete path to qmake from Qt you installed:

                              ~/Qt/5.10.0/gcc_64/bin/qmake

                                It's been a while but I experienced some of the issues described here and a few other forums. Just for whoever stumbles upon this issue, there is a small thing I overlooked when getting the source code from GitHub, namely:

                                If you clone from the GitHub repo, don't forget to check out a release version!

                                Current release is v5.15.0, but I was working from the dev branch, which caused a bunch of errors when compiling. After checking out release v5.15.0 everything suddenly worked.

                                  @lorn-potter How exactly do I compile this? I am a total newbie on these things. I'm using MSVC 2015 65. I cloned the repo and I opened the terminal in that folder, ran vcvars64.bat and tried qmake but it just gave me the instructions. Should there be a *.pro file in the directory.

                                    @Jari-Koivuluoma Did you checkout Qt5 branch? If you check https://code.qt.io/cgit/qt/qtmqtt.git/tree/?h=5.12 you will see that there is a pro file. I guess you are on master branch, which is Qt6 and based on CMake.

                                      Thanks, I had to study how to clone a specific branch. I just mistakenly assumed that the cloning link was automatically generated when I changed the branch. From there it went without a hitch.
