<div dir="ltr">thank you for the answer, I was looking at the examples... it seems they are not compiled in a "standard" way. In fact the output is a bash script and in top of this script there's a comment: # The echo-server program cannot be directly executed until all the libtool # libraries that it depends on are installed. maybe I'm missing some library? Tomorrow I will try again to resolve this issue regards, Claudio Contino <div class="gmail_quote">On Mon, Aug 18, 2008 at 6:09 PM, P.
