Jak w temacie, nie mogę skompilować pod linuxem tego kodu:

#include <boost/signal.hpp>
#include <iostream>

void func1()
{
std::cout << "Hello" << std::flush;
}

void func2()
{
std::cout << ", world!" << std::endl;
}

int main()
{
boost::signal < void() > s;
s.connect( 1, func2 );
s.connect( 0, func1 );
s();
}

Kompilator wypluwa coś takiego

Dodaje w eclipse do projektu -llboost_signals ale wywala mi /usr/bin/ld: cannot find -llboost_signals

A nie przypadkiem -lboost_signals przez jedno 'l'?
