[Boost-users] program_options, parse_config_file problems

Hello,

I am attempting to parse configuration options from a file using 
Boost::program_options. I am following the example provided on the 
website 
(http://www.boost.org/doc/libs/1_49_0/doc/html/program_options/overview.html#id2501135):

variables_map vm;
store(parse_command_line(argc, argv, desc), vm);
store(parse_config_file("example.cfg", desc), vm);
notify(vm);

I have included the following related to program_options:
#include <boost/program_options.hpp> // Boost Program Options
#include <boost/program_options/positional_options.hpp>
#include <boost/program_options/parsers.hpp>

I have the exact code as above in my program but receive the following 
error. The program works fine if I comment out the line with the 
parse_config_file line. Can someone please help me get this working.

Thanks,
Andrew
