hello there,
i'm unable to compile examples from wiringop.
this is my output:
  1. zero@orangepizero:~/WiringOP/examples$ gcc -o blink blink.c -lwiringPi
  2. //usr/local/lib/libwiringPi.so: undefined reference to `pthread_join'
  3. //usr/local/lib/libwiringPi.so: undefined reference to `pthread_create'
  4. //usr/local/lib/libwiringPi.so: undefined reference to `pthread_cancel'
  5. collect2: error: ld returned 1 exit status

Copy code


what's the matter?

You also have to link in the pthread library.  

This should get you going:

gcc -o blink blink.c -lwiringPi -lpthread
