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

Add -lrt to your link command. timer_create and timer_settime are not part of the C Standard library.

gcc -fPIC -shared libexample.c -lrt -o libexample.so
gcc -L. example.c -lexample -o example
