Hi,

I have reviewed the code, the compiler options and I have arrived to the 
conclusion that I was wrong and probably it was nothing about compiler 
options.

However, more deeply doubts have come and I would to ask to the clever people 
here if someone could light me. It's curious because there's another person in 
the orocos list that has similar problems, and probably our problems came from 
the same place.

The soem library, use some pthread to not block functions to send and receive 
packets. I think that I'm having problems here. I can setup a socket, but I 
cannot send any packet message in a simple program.

I got the idea of putting a:
   struct sched_param param = { .sched_priority = 1 };
   pthread_setschedparam(pthread_self(), SCHED_FIFO, &param);

in the send function, before rt_dev_send.

The raw-ethernet example use it, but if I put the same parameters I got a 
segmentation fault, The pthread library didn't like the pthread_setschedparam. 
I have reviewed and compiled by hand linking against pthread_rt , but the 
same.

Someone have some idea to solve this?

Thanks in advance,

Leopold
