ImportError: libwiringPi.so.3: cannot open shared object file: No such file or directory #6

Open Matebo opened 1 year ago

Matebo commented 1 year ago

I have a new Odroid C4 and some python code that was originally written for Raspberry Pi. I changed import RPi.GPIO to import Odroid.GPIO and followed the installation requirements from the readme. I get stuck on on ImportError: libwiringPi.so.3: cannot open shared object file: No such file or directory. Any suggestions?

From installation to ImportError

I have the same issue when running the example code 

user@odroid:~/tools/blink-python$ cat app.py
import Odroid.GPIO as GPIO
# You can also use 'import RPi.GPIO as GPIO'.
import time

'''
GPIO.BCM == GPIO.SOC
GPIO.BOARD
GPIO.WIRINGPI
'''
GPIO.setmode(GPIO.BOARD)

GPIO.setup(13, GPIO.OUT)

while True:
    GPIO.output(13, GPIO.HIGH)
    time.sleep(1)
    GPIO.output(13, GPIO.LOW)
    time.sleep(1)
ebo@odroid:~/tools/blink-python$ python3 app.py

We made a symbolic link from libwiringPi.so.3 to libwiringPi.so.2 in /usr/lib/aarch64-linux-gnu with 

ln -s libwiringPi.so.2 libwiringPi.so.3

I think it still needs a permanent fix
