Hi...I've  followed your  advice, and I have downloaded the new boost asio 
library, which support the fork().
I've downloaded the simple example at the following link:
http://think-async.com/Asio/boost_asio_1_5_2/doc/html/boost_asio/example/fork/process_per_connection.cpp,

but when I'm trying to compile I get the following error:


**** Build of configuration Debug for project ServerFork ****

any ideas?

Oggetto: Re: [Boost-users] program_options and BOOST_ALL_NO_LIB=1

A simple search would give you that
See
http://www.boost.org/doc/libs/1_46_0/more/getting_started/unix-variants.html
or
http://www.boost.org/doc/libs/1_46_0/more/getting_started/windows.html,
depending on your platform, point 3 for both.

Best,
Dee
