My code (simplyfication of this: 
http://www.boost.org/doc/libs/1_47_0/doc/html/boost_asio/tutorial/tuttimer1/src.html):

#include <iostream>
#include </usr/local/include/boost/asio.hpp> // Boost version 1.47.0
int main() { return 0; }

Compilation command:
g++ -Wall -o timer1 timer1.cpp

Error:

Any ideas?

Thanks in advance.
