    Hi,

    Where does it come from ?
    What device are you using ?
    What does /dev/cpuinfo return ?
    What distribution are you running ?

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

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

            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?

                    @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.

                        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.
