Make failed

[GeorgeJirka]

I have a USB2CAN device from www.canlab.cz (https://www.canlab.cz/cs/usb2can_interface) and when I try run make, it fails. Any idea, how to solve it?

Hi,

driver hasn't been tested with kernel 6.11, so it probably won't match system calls correctly. Also, this driver is only for USB2CAN Triple https://www.canlab.cz/cs/node/123 , not for regular USB2CAN .

You can either use virtual machine referenced in readme or update tty_mode_ioctl call and tty_struct so it matches tyour kernel version.
