I am trying to cross compile for a Raspberry Pi 4B and running into errors when building for the target device.

Is anyone available to help work through this? Right now I'm developing on Ubuntu and moving all of my source files to the Pi to build in place. This project will eventually have multiple devices that need to be updated. I won't be able to build from source for all them when I make functionality updates.

date is not a JS keyword, but a QML value type. But yeah, it would be good to have that more explicit in the documentation ...

@David-Bryant Hi and thank you for your willingness to help and share your feedback.

Thank you for the ping, folks! And I guess you have already explained a good chunk of it.

I understand some pages might indeed not need such restrictions. I will take this to IT and moderators so we can evaluate what options we have.

Please keep in mind most people are enjoying the summer holidays, so it will take some time to start the conversation.
In the meantime, feel free to message me directly with any suggestions and/or concerns. ✌️

@jsulm
ok, thanks...

@The-Times Happy coding!

@ZawPaing You have to retry later, dowload.qt.io is currently down. I don't know if there is a maintenance in progress or hardware issue on server.

You have to be patient

@AndyS I did another edit yesterday, but now they are both included. Also the older one. Thanks.

@bhagerty hi and welcome to devnet,

What using a custom build of Qt: always use the full path to qmake. You may have the one provided by your distribution installed which will be the one invoked. One other thing you did not take into account is unless you are doing a developer build (because you want to hack on Qt) you have to call 'make install' as last step.

@Theo_B I don't think there are any UML diagrams for Qt classes.

"as soon as I want to castes, or encapsulate the classes with Qt in C ++ c ' is very hard" - can you explain what exactly the problem is? In the documentation for each class you will find which classes it inherits.

Hi, @Chris-Kawa Thanks for your quick reply.

@Alphy said in same serial in multiple threads giving error:

it is working fine.

So please don't forget to mark your post as solved!

@apalomer Tankes for your anwser. you are a good man
