    What are you using that tries to access /dev/cpuinfo ?

      and what happens when you cat /proc/cpuinfo from the command shell?

      If you meet the AI on the road, kill it.

        I used wiringPi library in my code, and now i found out this library installed with problem. i installed this library from bellow link :
        http://wiringpi.com/download-and-install/
        and when i use "gpio -v" command bellow error apear again :
        Oops: Unable to determine board revision from /proc/cpuinfo
        -> No "Hardware" line
        -> You'd best google the error to find out why.

        unfortunatly, i cann't install wiringPi successfully and i think that my problem relevant to it.

          @Momeneh Where do you call gpio? On your RaspberryPi?
          As @Kent-Dorfman asked - what does "cat /proc/cpuinfo" on your RaspberryPi output?

            i used "gpio -v" command on terminal in ubuntu , becauce qtcreator installed in ubuntu, i want cross compile my code on raspberry pi after it run on qtcreator in ubuntu sucessfully.
            i don't check "cat /proc/cpuinfo" command. let me to check it.

                @Momeneh Shouldn't you use gpio on your RaspberryPi and not Ubuntu machine?

                  Just in case, there's an issue opened on the WiringPI-python project about that error.

                    @jsulm
                    Yes, i checked it on raspberry pi, i installed wiringPi on raspberry pi successfully and output of "gpio -v" command was true. Now i want to compile and run my code on raspberry pi. But i connect to raspberry pi with ssh from ubuntu and control it remotely. Now i copied my files to raspberry pi and i want to compile it with qmake but qmake don't install on raspberry pi and i don't know why.

                      @Momeneh You can use Qt packages provided by Raspbian if you don't need latest Qt version. This would be the easiest way.
