wiringPiISR: execl failed: No such file - Raspberry Pi Forums

-

hello colleagues,

i'm trying use interrupt function wiringpiisr wiringpi simple pir sensor alarm (sensor connected pin 17). , encounter following error:

wiringpiisr: execl failed: no such file or directory
wiringpiisr: unable open /sys/class/gpio/gpio17/value: no such file or directory

googling shows, wiringpiisr not find somehow gpio binary, in fact located in in /usr/local/bin , executable.

running "whereis gpio" gives: gpio: /usr/local/bin/gpio

running "gpio readall" command line provides correct pin readouts , sees sensor state changes.

no compilation errors.

strange, working before perfect! after failure of sd card, created new 1 yesterday freshly installed raspbian , wiringpi , strange error! :evil:

are running root?
