Undefined reference to a function in another library

Question

I\'m trying to compile an object code with a reference to one lib. This is the code of libexample.c:

#include \"libexample.h\"
#include 
#include         


        

Answer 1

Looks like you forgot to link in the library that defines timer_create and timer_settime -- you need to add -lrt to your gcc command.
