     When all required databases are loaded you should prepare the detection
     engine by calling <code>cl_engine_compile()</code>. In case of failure you
     should still free the memory allocated to the engine with
     <code>cl_engine_free()</code>:

     <PRE>
06e931e5
 	int cl_engine_compile(struct cl_engine *engine);
 </PRE>
     In our example:
     <PRE>
 	if((ret = cl_engine_compile(engine)) != CL_SUCCESS) {
 	    printf("cl_engine_compile() error: %s\n", cl_strerror(ret));
 	    cl_engine_free(engine);
 	    return 1;
 	}
