I am stuck on installing evdev==1.6.0 python package on my Ubuntu20.04(Focal) AMD64 machine.

Firstly, I tried

$ pip install evdev==1.6.0

and then, I got a error message below.

      The 'linux/input.h' and 'linux/input-event-codes.h' include files
      are missing. You will have to install the kernel header files in
      order to continue:
      
          yum install kernel-headers-$(uname -r)
          apt-get install linux-headers-$(uname -r)
          emerge sys-kernel/linux-headers
          pacman -S kernel-headers
      
      In case they are installed in a non-standard location, you may use
      the '--evdev-headers' option to specify one or more colon-separated
      paths. For example:
      
          python setup.py \
            build \
            build_ecodes --evdev-headers path/input.h:path/input-event-codes.h \
            build_ext --include-dirs  path/ \
            install
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for evdev

Following the message I tried

 $sudo apt-get install linux-headers-$(uname -r)

and the message said it is up-to-date.

Does anyone know a solution or something to try next?

Finally, I found that my header files, which are input.h and input-event-codes.h were in the wrong place. I searched the location and copied and pasted the into "/usr/include/linux/" and install gcc, evdev were successfully installed. Thank you for your comments.

  • Copying files under `/usr` (_anywhere_ in `/usr` except `/usr/local`) is generally a Bad Idea and makes for problems in the future. Better to make sure the place the files exist is added to your include path (for example, in some distros -- I don't remember offhand if Ubuntu is one of them -- there's a per-kernel-version header link in the same tree as modules; and if you're using a kernel module build framework like DKMS correctly, that location will be added to your compiler's path automatically). – Charles Duffy Jul 18 '23 at 16:04
