Problems with CANOPEN on arm Cortex

jsulm

@Nunzio I asked you to post errors as text...
You do not get this error if you connect your embedded board, you get it when you compile the application.

You also did not answer this question: Are you cross compiling these examples for the board?

What Qt version do you use?

JonB

@Nunzio
I know nothing about this, and @jsulm knows more and you should answer his questions, but just looking at the errors in your screenshot and comparing against the docs for QCanBusDeviceInfo at https://doc.qt.io/qt-5/qcanbusdeviceinfo.html I can indeed see that neither plugin() nor alias() are listed as members of that class, while e.g. name() (which you use but does not error) is there....

Nunzio

@jsulm
I’m using the cross compiler GCC
Qt Creator 4.11.0 based on Qt 5.12.12.8 (GCC 9.3.0, 64bit).

Nunzio

@JonB
thanks for help..
i will check

Thanks for all

@Nunzio
As I wrote above, those methods in the error messages do not exist on QCanBusDeviceInfo as you can see from that link.

I asked which Qt version you're using, not what Qt was used to build QtCreator.
So, which Qt version do you use?

Nunzio

I hope that these info can help us

How you can see I'm new in this world.

I have realized a program ( that works) with qt to move through relays some pistons; now I need to use the canopen protocol to move them. This is what I Know.

Thanks a lot for helping me and spending time for me

qt 6.2.4

I don't think you're using Qt6.
Because Qt6 has the methods and you would not get these errors, see https://doc-snapshots.qt.io/qt6-dev/qcanbusdeviceinfo.html
Make sure you really use Qt6.
