I placed the wrong example. I used an example for don't send complete code.

The real problem is in my small application.
Could someone help me? Only executing a simple "make".

My application is:  http://www.felicio.com.br/mcast.tar.gz

It is a simple multimedia server multicast using RTP.

Thank you.
