WiringOP problem

diyer

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
   
6. 
   

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
