Hi,
I'm new to Boost and I've decided to use it in my C++ project. My first
attempt is to use boost::program_options. However, Im hitting a slag and I
can't figure out whats the problem.

ive got this:

#include "boost/program_options.hpp"

int main()
{
  return 0;
}

then I run:
g++ -I/usr/local/include -L/usr/local/lib test.cpp

but I get this error that doesn't make any sense to me:

I tried including other libraries like foreach and thread and they compile
& link fine.

Can someone please help me?

Thanks,
