Hi David, thanks very much for your suggestion; At first your program didn't work either, and using strace I found out that indeed it couldn't find something: my own program! I forgot to put the './' in the second argument of exec (arg[0])... So it was looking in all the wrong places :-\ Guess I was thrown off-track by the error message, thought it had something to do with the libraries...
So thanks a lot!!
