How do I compile simple gearman worker with C?

I am trying to compile a simple gearman worker on C. I use mac. Here is the code: 

#include <libgearman/gearman.h>
int main(void) {
    gearman_worker_st worker;
    gearman_worker_create(&worker);
    gearman_worker_add_server(&worker, "localhost", 4730);
    return 0;
}

When I try to compile it with:

#gcc test.c 
Undefined symbols for architecture x86_64:
  "_gearman_worker_add_server", referenced from:
      _main in ccLUuf8y.o
  "_gearman_worker_create", referenced from:
      _main in ccLUuf8y.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

I know I have to link gcc with gearman but when try:

#gcc test.c -lgearman
ld: library not found for -lgearman
collect2: ld returned 1 exit status

Any ideas?

Did you install Gearman on your machine? If so, where did you install it? Since it appears you have the header, the library is probably around somewhere. Did you specify a location to find the headers? If you said -I/some/where/include for the headers, then you should probably say -L/some/where/lib to find the library. I don't seem to have Gearman installed on my Mac; I know I've not installed it, and it doesn't seem to be in /lib, /usr/lib, /usr/local/lib or /Developer. - Jonathan Leffler
I just found out port have not installed gearman properly. Installed it with brew and all works fine. - Ivelin

maybe your need to define the lib path, like -L/usr/lib/, use your libgearman.a stored path to substitute -L/usr/lib/

maybe your need to define the "include path" and the "lib path", for example, the head file "libgearman/gearman.h" in the /usr/local, the library libgearman.so in the /usr/local/libgearman/lib

the compile command like, gcc -I/usr/local -L/usr/local/libgearman/lib test.c -lgearman

As stated here, you have to link it with -lgearman

gcc test.c -lgearman
