Thanks for the quick answer. I will try to investigate a bit further to see if there are any errors.<br>
If anyone on the list can test the code and report results, that might be helpful as well.<br>
<br>
I'm attaching the Makefile I used to compile (removed all glib stuff, maybe this where the error is):<br>
