libevdev error

[akramraza2]

I installed libevdev and when tried to compile any of the given examples it gives various errors . Mainly for those functions calls which are done from libevdev.h file.

What's the output from the pkg-config line? What distro are you using? If you are on Ubuntu I think you have to install libevdev-dev.

[akramraza2]

undefined reference to libevdev_new_from_fd' undefined reference to libevdev_uinput_create_from_device'
undefined reference to libevdev_grab' undefined reference to libevdev_next_event'

I am using Ubuntu and I have libevdev-dev installed, otherwise it directly gives error saying <libevdev/libevdev.h> file not found. And, also the same for <libevdev/libevdev-uinput.h> file not found. So , all the errors are related to the libevdeb=v function calls.

It seems that the shared library it's missing. You probably have something not installed, it should be an easy fix, let me know

Have you tested your code ? I checked everything , it still doesn't work. So , maybe you should provide a readme for the steps you followed to successfully test this.

hi, instead of

gcc `pkg-config --cflags libevdev` `pkg-config --libs libevdev` example_name.c

try to run

gcc `pkg-config --cflags libevdev` example_name.c `pkg-config --libs libevdev`

That should work
