[Ecls-list] Embedding ECL library in C program

I'm trying to build a simple "hello world"-like example, but not doing very well so far.
Here is my C code:


#include <stdio.h>
#include <ecl/ecl.h>

int main(int argc,char** argv)
  cl_object res;

  return 0;

and ECL library code:


(defpackage "TEST"
(:use "COMMON-LISP")
(:nicknames "TEST")
(:export "GET-MSG-TEXT"))

(in-package test)

(defun get-msg-text()
(values "Hello from ECL!"))

I'm getting this error in the first step of the building process:

$ gcc -I/usr/share/lib/ecl -c prog_msg.c
prog_msg.c: In function 'main':
prog_msg.c:9: warning: assignment makes pointer from integer without a cast
prog_msg.c:10: error: 'union cl_lispunion' has no member named 'string'

What am I doing wrong?
