To get more your system information, type
uname -a
and cat /etc/debian_version
and cat /usr/src/linux-headers-$(uname -r)/.config | grep UINPUT
in your terminal and send me the results.
Also, check whether /dev/uinput or /dev/input/uinput is existing.

You have to enable uinput. Because I don't have debian system, i am not sure of this.
Change the option CONFIG_INPUT_UINPUT=m to CONFIG_INPUT_UINPUT=y in the .config file.

from chosuntruck.

modify that to "y" and reboot, still failed,
or need recompile the kernel with the headers?

debian:~/ChosunTruck-master/linux$ cat /usr/src/linux-headers-$(uname -r)/.config | grep UINPUT
#CONFIG_INPUT_UINPUT=m
CONFIG_INPUT_UINPUT=y

debian:~/ChosunTruck-master/linux$ ./ChosunTruck -D
error: open: No such file or directory

from chosuntruck.

I'm sorry. Revert your .config file.
Uinput is built as a module in your debian. So, you need to insert the uinput module.
modprobe uinput
lsmod|grep input
ls -l /dev/uinput
I found this solution from https://bbs.archlinux.org/viewtopic.php?id=203169

@bethesirius thanks, that's works.

// use sudo can create it now

Okay, I will change the ambiguous error message :)
And, your new OpenCV Error is difference from the uinput issue. I recommend that you close this and open new issue.

Hi, actually I had the same issue and ended up the same as the @gotope 's last posting, which is the OpenCV Error. Has this issue been opened or resolved somewhere? Thanks.

from chosuntruck.

@mrasyid No, it didn't. Please open a new issue with your enviornment like OS version, if you still have that trouble. Thanks.
