install "serialbus" module
-
@Pablo-J-Rogina Yes, i'm agree with you. But I had some doubts :-| . Because it didn't work anyway.
I tried to launch some modbus examples. But I didn't find them...
I don't understand why. Because i installed all possible qt examples packages with this command : apt-get install qt.*example.
@SGaist I installed Qt creator and all other qt packages with apt-get command.
Then I tried to install serial bus module with linux qt installer (qt-unified-linux-x64-3.0.6-online.run). But it didn't work. Because the downloading is VERY slow.
And, to be more specific, i have this error when I run make :
/usr/lib/qt5/bin/qmake -o Makefile modbus_com.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug Project ERROR: Unknown module(s) in QT: serialbusThank you

This will not help as you can't mix your Linux distributions Qt packages and those installed via Qt installer.
On my Ubuntu system I see libqt5serialport5 package - did you install it (and its -dev packet)? -
@jsulm yes, i installed libqt5serialport5 and libqt5serialport5-dev packages.
@dfvgergver What happens if you remove "-spec linux-g++"?

nothing good :-(
I have this message : "make: *** No rule to make target 'common/xxx_params.cpp', needed by 'xxx_params.o'. Stop."But it's normal.
Because, I have a project A which to work must include a project B (a kind of template I suppose).
However, it is this project B that requires the "serialbus" module. That's why I tried to compile this project B to "get closer to the problem". But it makes no sense to compile project B since it is intended to be included in another project.
Sorry if my explanations are a little esoteric. I am a new Qt user (I only know him for 2 days...). -

Sorry if my explanations are a little esoteric. I am a new Qt user (I only know him for 2 days...).The package you need is
qtserialbus, notqtserialport.If your distribution does not provide it, you have two options:
- Install the complete Qt with the online installer
- Use the distribution Qt packages and compile qtserialbus from source. The source code can be cloned with Git from git://code.qt.io/qt/qtserialbus.git

I'm trying the option two.
But, when i execute make (after run qmake), i have this error :
qcanbusdevice_p.h:43:10: fatal error: private/qobject_p.h: No such file or directory #include <private/qobject_p.h> ^~~~~~~~~~~~~~~~~~~~~And from qtcreator when i open the .pro file and try to compile :
So, i'm trying to find the package which contain the "private/qobject_p" library. But, i don't find him...

@dfvgergver is it a good reason you're using "Qt creator 4.5.2 based on Qt 5.9.5"?
I'd suggest that instead of go looking for a needle in the haystack (i.e. building yourself the Qt Serialbus module, you install Qt 5.12.0 (or 5.12.1) that will provide you with the module you're looking for in a smooth way...

I would like to be able to install the 5.12 on my linux mint. But I can't go through the Qt installer to install Qt 5.12 (see above): the connection is too slow.

Hi
I wonder if using another server would help ?
https://github.com/JKSH/QtSdkRepoChooserHowever, if its the actual connection that's too slow it won't help.

Could it be possible you use any of the offline installers?

I use qmake & make to compile the source then something happen with these below:
qcanbusdevice_p.h:43:10: fatal error: private/qobject_p.h: No such file or directory
Anyone who can tell what's wrong with it . I guess the module sources of qt on github more or less give some tips for users how to build them but nothing clue happened so far. By the way i'm using ubuntu 18.05 and no serialbus module for this platform, please help! -
I build serialbus with the following instructions (also mirrored in this gist: https://gist.github.com/awesomebytes/ed90785324757b03c8f01e3ffa36d436):
# Overkill: get all qt-stuff sudo apt install qml-module-qt-labs-folderlistmodel qml-module-qtquick-extras qml-module-qtquick-controls2 qt5-default libqt5quickcontrols2-5 qtquickcontrols2-5-dev qtcreator qtcreator-doc libqt5serialport5-dev build-essential qml-module-qt3d qt3d5-dev qtdeclarative5-dev qtconnectivity5-dev qtmultimedia5-dev # To get rid of the private/qobject_p.h error sudo apt-get install qtbase5-private-dev # Build and install qtserialbus git clone git://code.qt.io/qt/qtserialbus.git cd qtserialbus git checkout 5.9.8 qmake make -j6 sudo make installI hope it may be useful for someone else.
I found that qt in Ubuntu 18.04 from official apt repositories (Qt 5.9.6) didn't have serialbus so it needs to be built and installed like that.
