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>
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;
}
</PRE>
