    @SGaist said in How can I use the QtMqtt code?:

    you'll already have the module with Qt so no need to build it by hand.

    Qt MQTT is not part of "standard" Qt 5.12 distribution... From documentation:

    Note: Qt MQTT is part of the Qt for Automation offering and not Qt. For further details please see Qt for Automation.

    @JoeBermejales have you try building the module from command line?, like this:

    git clone git://code.qt.io/qt/mqtt.git -b 5.12
    cd mqtt
    qmake
    make
    make install

    Yes, but I get some errors. I did the following:

    • I downloaded the qtmqtt 5.11.2 branch (corresponding to my Qt current version -in previous question and setup it was 5.12.2, but get the same error-) and extracted to the following path:

    0_1552654365460_c8129aeb-494e-4175-a7fe-efd4eafd5902-image.png

    • I opened the Qt console and navigate to the path and executed the qmake and make commands that you described:

    0_1552654459379_f7274d56-d30c-4891-843c-12e2d1fd84b1-image.png

    0_1552654563937_9ea85648-709f-4fd7-a58d-b047b247996c-image.png

    • qmake seems to be valid:

    0_1552654583199_f7bbf2a5-e3e5-4fd4-be00-e8178cf2372b-image.png

    • But make is not:
      0_1552654642478_f5e0f45d-936e-4ccf-96f5-b3914259535e-image.png

    • So I tried with mingw32-make and get the following error:

      @JoeBermejales maybe this post I did some time ago should help.

      It looks like you need to ask qmake to recurse subdirs with the -r argument.

        @Pablo-J.-Rogina thank you, but after following the suggested instructions nothing seems to work, and I had multiple errors, so I started from the beginning with Qt Creator.

        1. I downloaded and extracted the 5.12.2 Mqtt version corresponding to my Qt working version.
          0_1552911676522_1e5722ec-2812-418a-8a95-f7ff1825b5ae-image.png

        2. I opened the root level .pro file

        0_1552911770125_27356426-832a-4046-a549-b6e181b2942e-image.png

        1. I configured with the Qt 5.12.2 MSVC2015 64bit version:

        0_1552911810756_b45da8da-83fa-4bb3-bd25-929da28dd9ac-image.png

        1. I get the following errors:

        0_1552911850606_b02db119-9b47-4439-a8e3-e07f078a71d9-image.png

        1. If i try to build the project, I get the following errors:

        0_1552911934174_ca6c93c8-e16f-46fb-ae77-2a87bbcad061-image.png
        6. After the previous errors, I first execute qmake from Qt Creator (Build -> Run qmake) and seems to work fine with no errors:

        0_1552912087070_82aaf512-2edd-4cad-9a18-edd5e329f46a-image.png

        1. I build again but the original errors remain:
          0_1552912196214_a335324e-07bc-49a0-9947-6bf951a6a6c0-image.png

        Please, any idea?

        Thanks

          Do you have perl installed on your machine ?

            @SGaist yes, and I tried to reinstall Qt 5.12.2 with Mingw 7.3.0 64bits and get the same errors:

            0_1553006226110_e07b43fb-5441-4876-8158-cca84068f1f5-image.png

            I will try in another computer, we really need the QtMqtt code to communicate to a remote device.

            Thanks again @SGaist

                  @JoeBermejales HI, finally I modified the source code and it works!! I removed the QtMqtt/ in the includes as shown in the following screenshots:

                  I changed this:
                  0_1553072624291_baa7a81b-9c50-43ff-818d-ba51a274468b-image.png

                  For this, en every .h file:
                  0_1553072682284_aebd950b-4ec6-4c82-a85d-d7b4999be662-image.png

                  And now it compiles!!!

                  Thanks to @SGaist and @Pablo-J-Rogina for your help! :)

                  I summarize here the way I achieved to compile and use the official Mqtt source code in Windows 7 Pro:

                  1. Download source code from https://github.com/qt/qtmqtt (pay attention to your Qt version)
                  2. Extract the zip and open the root .pro project with Qt Creator and navigate to src .h files
                  3. Remove all the necessary <QtMqtt/ prefixes in order the routes to be recognized and fix the path errors presented on .h files
                  4. Compile for your current kit (in our case, Windows 7 64 MSVC 2015 Community Edition 64 bits Qt 5.12.2)
                  5. Copy the .h files and lib directory to your local lib path
                  6. Add the following code to your .pro file (correct the relative routes if necessary)
                  win32:CONFIG(release, debug|release): LIBS += -L$$PWD/mqtt/lib/ -lQt5Mqtt
                  else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/mqtt/lib/ -lQt5Mqttd
                  INCLUDEPATH += $$PWD/mqtt/src
                  DEPENDPATH += $$PWD/mqtt/src
                  win32:!win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/mqtt/lib/Qt5Mqtt.lib
                  else:win32:!win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/mqtt/lib/Qt5Mqttd.lib
                  
                  1. In your code, you can include the library classes as follow:
                  #include <qmqttclient.h>

                      @autoantwort said in How can I use the QtMqtt code?:

                      My username contains a space and this created a problem

                      Avoid the problem using a path without spaces in it...
