Momeneh

can you help me for solving this problem?

after i run my qt application, this error apear.

Hi,

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

@SGaist
I intend to turn on and off a led(or a blinking led) using raspberry pi3 and i also want to firstly do this in qtcreator in ubuntu enviroment and then cross compile it on raspberry pi,
But when i run the code on qtcreator, this error apear.

SGaist

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

Kent-Dorfman

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

Momeneh

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

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

you can see the result of "cat /proc/cpuinfo" command on raspberry pi :

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

SGaist

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

Momeneh

@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.
