Error CAN Bus example implementation in QtCreator 4.14.1 Based on Qt 5.15.2

imene

I'm trying to implement this project in QtCreator (https://code.qt.io/cgit/qt/qtserialbus.git/tree/examples/serialbus/can?h=5.15.2)

OS: Raspbian GNU/Linux 11 (bullseye) [linux version 5.15.53-v7+]
Qt Creator 4.14.1
Based on Qt 5.15.2 (GCC 10.2.1 20210110, 32 bit)

But i face many errors:
I create new project then i added classes and .qrc file,
i only change can.pro file to addapte it to my project from this(code in the website):

To this:(i only added line 4 and 5 "QT += serialbus widgets
requires(qtConfig(combobox))" to can.pro in my new project)

@imene Please show the content of the main.cpp file.
And also the whole build log would be helpful.

Hi @jsulm i take the same code main.cpp from this site (https://code.qt.io/cgit/qt/qtserialbus.git/tree/examples/serialbus/can?h=5.15.2),

jsulm

@imene Try a complete rebuild:

Delete build folder
Run qmake
Build

Okay @jsulm, i get this:

Did i have to delete bitratebox.ui ? because it doesn't exist here(in the site):

jsulm

@imene Errors are self explanatory: the class name seems to be bitratebox, not BitRateBox (check bitratebox.h).

imene

@jsulm

jsulm

@imene So, as you can clearly see the name of the class is bitratebox...

@imene
Where your bitratebox.h file comes from ?

Here the file from the git:
https://code.qt.io/cgit/qt/qtserialbus.git/tree/examples/serialbus/can/bitratebox.h?h=5.15.2

Abviously not the right one !

Thanks guys @jsulm & @mpergand it works now!
i've been using a wrong bitratebox.h bitratebox.cpp files now i take the right ones from the site :
