qtmqtt build on windows
-
Hi and welcome to devnet,
There's no need to build the whole of Qt if you only need the QtMqtt module, just build it with the version you already use for development.
Also, unless you plan to hack on Qt itself, drop the developer-build option.
@SGaist @Pablo-J-Rogina
Thanks for the your help.
When I try qtmqtt build using mingw32-make below errors are comeC:\Qt5\qt5\qtmqtt\src\mqtt\qmqttconnection.cpp:169:39: error: 'errorOccurred' is not a member of 'QAbstractSocket'

The idea is that you have Qt already installed, either by installing pre-built files for your OS or by building Qt yourself, before building mqtt module.
Is that your case?
Could you please describe your environment (OS, Qt version, how you installed it, etc.)? -
I'm having the same issue using the last version of Qt and Qt Creator on Linux 20.04 .
I used the following commands in the terminal:- git://code.qt.io/qt/qt5.git
- cd qtmqtt
- qmake .
- make
and the make command returns the same error described above:

If you did nothing special, then you have the dev branch checked out. Switch the the branch matching your Qt version.

@SGaist Thank you for your fast reply, how can I do that?

Using
git checkout <name of the branch/tag> -

@SGaist I downloaded the correct version (for Qt 5.15) but now it returns a new error:

Did you cleanup before restarting the build ?

Following this thread https://forum.qt.io/topic/100705/how-can-i-use-the-qtmqtt-code/14 , I remove all the "QtMqtt" from the headers files, now I can build the project without errors.
On the other hand when I run the project, in the application output panel I get this error:10:41:49: Starting /home/furla/Qt/EDALAB/build-qtmqtt-Desktop_Qt_5_15_0_GCC_64bit-Debug/examples/mqtt/consolepubsub/qtmqtt_pub ... 10:41:49: The process failed to start.

- MakeFile
*Makefile.qtmqtt_pub
*MakeFile.qtmqtt_sub
And if I use the command make in this folder I get this error:

What do you mean with cleanup?

Nuke the build folder to ensure there's no stuff from your failed attempt that will influence this new one.
Then ensure you have all the required tools to build Qt from git since you cloned the sources from there. Since you are on Linux, it is likely the case but better check then guess.

@SGaist Ok I already deleted everything before to retry and as I described above I'm getting a new error.
I think I have all the right tools installed and also the Qt Creator options should be ok since I can run every example project without problems.
Moreover, instead of using the command clone, I maually downloaded the .zip folder from git corresponding to my Qt version -
Can you give what your actual state is now ?
Did you build the module successfully ?
If so, did you call the equivalent of make install ? -
For other searchers!
There is a dependency package, at least on RPi by the name of:
qt5base-private-devin order to build qtmqtt.
@SGaist , thanks for the prompt on
git checkout <version>as I keep forgetting that detail when seeking a specific version.
