[Ecls-list] Getting "hello world" going

[Goffioul Michael]

You have to initialize ECL engine before calling ECL functions. Use
cl_boot for this.

	I know I'm being a bit vague here, but it's not really happening
for me. . Suppose, instead, I have hello.c:
	
	#include <ecl/ecl.h>
	
	main()
	{
	  cl_object form, result;
	  form = c_string_to_object("(+ 1 2)");
	  result = si_safe_eval(4,form, Cnil, OBJNULL );
	}
	
	and I compile it using
	    gcc -lecl hello.c
	When I type
	    ./a.out
	I get
	    Segmentation Fault

	I am trying to call Lisp code from C.
	
	Suppose I have the Lisp file sayhello.lisp:
	
	(defun say-hello () 
	    (print "hello world"))
	
	
	and a C file hello.c:
	
	main()
	{
	    say_hello();  /* ?? */
	}
	
	How do I compile everything into a program so that it all works?
