Hi,

I am a newbie to Boost. I am writing a sample code using the Boost libaries
and am getting the following error during linking.

*Command Line Usage *
*
**g++   -I /usr/include/boost/  example.cpp -o example.o*

*Code*

*#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>
#include <boost/program_options/options_description.hpp>
#include <boost/program_options/positional_options.hpp>
#include <boost/program_options/variables_map.hpp>
#include <boost/program_options/parsers.hpp>

#include <cstdlib>
#include <iostream>
#include <iomanip>
#include <map>
#include <string>

using namespace boost::program_options;
//namespace po = boost::program_options;

int main()
{
    using namespace boost::lambda;
  //  using namespace boost::program_options;
    typedef std::istream_iterator<int> in;

    std::for_each(
        in(std::cin), in(), std::cout << (_1 * 3) << " " );
    option_description opts;
}
*
*Error Message*

/tmp/ccO0HWa7.o(.text+0xb0): In function `main':
example.cpp: undefined reference to
`boost::program_options::option_description::option_description()'
/tmp/ccO0HWa7.o(.text+0xbf):example.cpp: undefined reference to
`boost::program_options::option_description::~option_description()'
collect2: ld returned 1 exit status

$LD_LIBRARY_PATH has the following value set.
/home/suhas/boost/lib:/usr/lib:/usr/include/boost/

I am stuck, any help will be really appreciated.

Thanks in advance.

Regards,
Eswar
