run as root on target device (cross compile raspberry)
-
Hey guys,
I'm currently writing my first application for a raspberry PI. As my app uses libpigpio I need to run the app as root.
How can I setup qt-creator to run as root on my target machine (rasp) ?cu
mts@themts Are you sure the only option is to run as root? Can't you add your user to the correct group which has access to gpio?
See https://raspberrypi.stackexchange.com/questions/40105/access-gpio-pins-without-root-no-access-to-dev-mem-try-running-as-root/40106
It looks like there is gpio user group - add you user to that group. -
I'm using this lib:
https://github.com/joan2937/pigpio
I think there is no such possibility.I could use pigpiod_if2 as this talks to a deamon which is running as root but I don't know what performance problems I will get.
As I want to communicate via wiegand to an RFID-reader I need some good timings (on a non realtime-os ...).

I know. But this lib simply access the device file for the gpio. That's why I suggested to change the access rights for it or add your user to the group set on the device file. Did you check the link I provided?
