      @MrShawn said in Cannot load library libsocketcan, some functionality will not be available: Did you try read/write on the canbus? I remember seeing this issue and it still worked and was able to do everything I wanted to on the CANbus. Read/write OK. Worked.

      @Saman19 said in Qt on MarsBoard, Cross compile error, Socket can fd: Note: QtSerialBus: Newer kernel needed for flexible data-rate frame support (canfd_frame). It does not seem to me a problem but an informative note. If you do not use CAN, check: Is Kernel Network CAN enabled? Something like: Networking support ---> <M> CAN bus subsystem support ---> --- CAN bus subsystem support <M> Raw CAN Protocol (raw access with CAN-ID filtering) <M> Broadcast Manager CAN Protocol (with content filtering) CAN Device Drivers ---> <M> Virtual Local CAN Interface (vcan) <M> Platform CAN drivers with Netlink support Mandatory, because under the kernel is the SocketCAN that handles this. Install the can-utils package It is necessary to include / install QtSerialPort, not for CAN but for ModBus that is part of QtSerialBus. Cleiton Bueno Blog | Linkedin | B2Open

      Hi and welcome to devnet, The module being pretty new (maybe even technical preview), I'd recommend posting this question on the interest mailing list. You'll find there QtCanBus developers/maintainers. This forum is more user oriented.
