@Dean21 @JoeCFD asked where the mqtt libs you built are stored, not where the code is...

@SGaist Ok, thanks!

system() is the naive OS interface mecahnism. It will stall the calling program while executing. an async QProcess is a better mechanism if you must call a subshell...The sophisitcated Linux way is to use the dbus system to talk directly to NetworkManager.

@Asperamanca said in mapToGlobal, wrong values with Linux:

Yup that looks like it.

@d_mcknight This issue is indeed specific to Ubuntu 22.04, I came across it today. The solution is to do sudo apt upgrade first. After it, qtbase5-private-dev is not trying to uninstall the whole system anymore.

@mrjj Hi Again,

I just noticed that despite not being able to pair, I can connect to the bluetooth module using connect (in bluetoothctl).

Could it be that Qt internally always tries to pair before connect, and that's why it cannot connect?

I was asking for the exact Qt version because of this: https://bugreports.qt.io/browse/QTBUG-97054

@SGaist i just used an older version of qt(5.12 instead of 6.1.2), and it worked

@aliemrenebiler said in Run a terminal command with a button click:

QProcess is not working, the program never opens and says as output "QProcess: Destroyed while process ("...") is still running.".

The problem would appear to be that your QProcess object goes out of scope (is destroyed) while the process you asked it to launch is still running i.e. exactly what the error message says. This is most likely because you have create the QProcess on the stack in the slot handling your button click, but it could be because it is parented to another QObject that is destroyed.

We can only guess without seeing your code.

@JoeA-B said in PkgConfig cannot find directfb:

Why not link? I am adding a module to a full operating system and cannot control the rest of the configuration

still a simple -ldirectfb parameter should work on all systems, when the plugin is in a default lib directory (which /usr/lib/x86_64-linux-gnu is btw for example on Debian/Ubuntu)

I can also vouch for the ease of using aqt on linux (and other platforms, too).

Pretty sure this qualifies as an unofficial/unsupported method, but it works:

Hi @TUStudi,

just to add that this problem is tracked as QTCREATORBUG-24561.

@Chris-Kawa Thanks, it works !

@Yalimyulad said in Post installing Qmake for new devices:

Is it possible to somehow copy the Qmake I have built from raspberry pi to my desktop?

Nothing is physically stopping you, but it won't work.

qmake is created and specific to the Qt FrameWork/Compiler used for that framework.
The compiler on your pi is not the same as the one you would use for cross compiling

If you want to really cross compile for the Pi , you will have to jump through some loops.
There are some guides out there for example this wiki entries

@Dariusz said in WSL Qt Ubuntu?:

how can I install Qt on Linux in shell?

sudo apt install qt5-qmake

Or use @benlau's excellent Qt silent installation scripts: https://github.com/benlau/qtci

Or compile Qt yourself.

@sneubert Thanks :)

@lucaszanella
Do you have a resource file named openglunderqml.qrc ?
Can you refer this example?
