Firstly thanks for replies, As I said there is no input folder in /dev path here is the output,
SHLL [/] # ls -las /dev/input /dev/input: No such file or directory Here is what I did for use libbsd and evdev, I builded rtems-freebsd with this, $ ./waf configure --prefix="$HOME/development/rtems/5" --rtems-bsps=arm/beagleboneblack --buildset=buildset/default.ini $ ./waf $ ./waf install Even so, when I realize that there is no input.h or evdev.h file in rtems includes , I changed some values in the libbsd.py file. Here the things I changed, I added 'freebsd/sys/dev' and 'freebsd/sys/dev/evdev' paths to include-paths. I added 'freebsd/sys/dev/evdev' path to header-paths. After that, I did waf again and here is the outputs; $ ./waf ... [1519/1939] Compiling freebsd/sys/dev/evdev/evdev.c ... ./waf install ... + install /home/furkan/development/rtems/5/arm-rtems5/beagleboneblack/lib/include/dev/evdev/evdev.h (from freebsd/sys/dev/evdev/evdev.h) + install /home/furkan/development/rtems/5/arm-rtems5/beagleboneblack/lib/include/dev/evdev/input-event-codes.h (from freebsd/sys/dev/evdev/input-event-codes.h) + install /home/furkan/development/rtems/5/arm-rtems5/beagleboneblack/lib/include/dev/evdev/input.h (from freebsd/sys/dev/evdev/input.h) ... I'm not sure if this is the right way to use evdev. This is how my application compiles without errors but still there is no /dev/input file.
