Qt 6

Well, turned out my qmldir was incorrect.
it is strange that it worked under QT5 however.

Doh! There's a Conan option qt5compat.

Moved to Qt6

@SGaist Please excuse my horrible grammar and form of the post. I am sure that dropping qmake_paths will work; however, it took a very long time to process until the final error, but my question was about the qt3d product that was formed: It looks complete and good. Stop! The Linux qt3d install finally worked! Here is what I used:
export PATH=/home/bob/Qt/Tools/bin:/home/bob/Qt/Tools/Conan:/home/bob/Qt/Tools/Ninja:$PATH
cd /home/bob/Qt/Conan3D
source /home/bob/vulkan/1.2.170.0/setup-env.sh
conan install qt3d/6.0.1@qt/final --build=missing --profile=/home/bob/Qt/Tools/Conan/profiles/'''qt-6.0.2-gcc-x86_64''' -s build_type=Release -g cmake_paths -g=cmake -g deploy -g=qmake
To remove the conan locks I had to use:
/home/bob/Qt/Tools/Conan/conan remove -l
As to the Win 10 qt3d, the following lines of the Linux install make me believe that I need to redo it:

Thanks for all your help, I am sure I will have more questions as I try writting qt3d programs.

@fari35 said in increment variable of server class for each thread:

How can I do that?

Emit a signal in each thread as soon as a new client connects. Connect a slot to that signal and increment the count variable there.

Check out https://wiki.qt.io/Qt6_Add-on_src_package_build_using_Conan_package_manager . The easiest setup currently is to install qt3d into the Qt SDK by running

<QtSdk>/Tools/Conan/conan install qtnetworkauth/6.0.2@qt/final --build=missing --profile=<QtSdk>/Tools/Conan/profiles/<right_profile>

Hi and welcome to devnet,

Do you have cmake installed and if so which version ?

That said, /opt is usually not user writable so you should do an out of source build from somewhere you can like your home folder (doing it as root is a bad idea).

You have a chapter in the Eigen documentation on how to use the library with a cmake project.

set Transformation Anchor for Your QGraphicsView
QGraphicsview::setTransformationAnchor(QGraphicsView::AnchorUnderMouse);

I am using same solution and it is working correctly.

it seems 6.1 includes State Machines https://wiki.qt.io/New_Features_in_Qt_6.1

@Gunkut See https://forum.qt.io/topic/122548/serial-port-for-qt-6
Qt6 does not yet contain serialport module.

You need to deploy your application.
I use the cqtdeployer tool for solve this issue.

Examples of using available here, here and here

You can download this deploy tool from github releases or snap store if you use Linux systems.

Great, thank you for the clarification - I must have overlooked this document:
https://www.qt.io/blog/add-on-support-in-qt-6.0-and-beyond

Cheers! P.

No that looks fine. Using static dependencies does not automatically trigger a static library creation.

It's seems to be a bug indeed.
