Hello,

I run into following problems compiling a programm what uses 
boost::program_options under  gcc version 3.4.2 / mingw:

here is the fragment that causes that behavior:

---------------------------------------------------------------------------------------------------------------------------
        // Declare the supported options.
        po::options_description desc("Allowed options");
        desc.add_options()
            ("help", "produce help message")
            ("client_id", po::value<int>(&mClientId),
            "set em's client id.")
            ("srv_ip", po::value<string>(&mSrvIp),
            "set SWRM server ip adress. Default is 127.0.0.1")
            ("srv_port", po::value<int>(&mSrvPort),
            "set SWRM server port number. Default is 8011")
            ;
        
        po::variables_map vm;

// trouble starts with commenting in the following line(s):

//	po::store(po::parse_command_line(globalArgc, globalArgv, desc),
//		vm);
//	po::notify(vm); 
//	
//	if (vm.count("help"))
//	{
//    	cout << desc << "\n";
//    	exit(EXIT_SUCCESS);
//	}
//	
//	if (0 == mClientId)
//	{
//		cout << "No client_id set. Exiting...\n";
//		exit(EXIT_FAILURE);
//	}
//	if( 2 > mClientId )
//	{
//		cout << "Client_id has to be greater than 1."
//			<< " 1 is reserved for SWRM server. Exiting...\n";
//		exit(EXIT_FAILURE);
//	}else
//	{
//		cout << "client_id of this EM was set to "
//			<< mClientId << "\n";
//	}
//	
//	if (vm.count("srv_ip"))
//	{
//    	cout << "SWRM server ip set to " << mSrvIp << "\n";
//	}else
//	{
//		cout << "SWRM server ip set to " << mSrvIp << "\n";
//	}
//	
//	if (vm.count("srv_port"))
//	{
//    	cout << "SWRM server port set to " << mSrvPort << "\n";
//	}else
//	{
//		cout << "SWRM server port set to " << mSrvPort << "\n";
//	}

All does compile fine under linux. And also the other boost libs I'm using 
(filesystem and date_time) behave well.

What I'm doing wrong?

Thank you in advance!
