Hello, when I am trying to link boost::filesystem into my program I am receiving link errors.  I am trying to convert from boost 1_34_1 to 1_36_0- previously this built against 1_34_1 without any issue.

When I link I get the following error:
/home/kstevens/code/CrossingEngine/../lib/libtypes.a(Config_Constants.o): In function `boost::enable_if<boost::filesystem::is_basic_path<boost::filesystem::basic_path<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, boost::filesystem::path_traits> >, bool>::type boost::filesystem::exists<boost::filesystem::basic_path<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, boost::filesystem::path_traits> >(boost::filesystem::basic_path<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, boost::filesystem::path_traits> const&)':
/usr/include/boost/filesystem/operations.hpp:279: undefined reference to `boost::filesystem::detail::status_api(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int&)'

I did an objdump -CT on libboost_filesystem-gcc42-mt-1_36.so and got the following two functions as output but not the one the linker appears to be looking for:
000000000000c4e0 g    DF .text  00000000000000e3  Base        boost::filesystem::detail::status_api(std::string const&, boost::system::error_code&)
000000000000c720 g    DF .text  00000000000000e3  Base        boost::filesystem::detail::symlink_status_api(std::string const&, boost::system::error_code&)

Could this be a bad build? Am I missing something- perhaps I need to link another file in? I built 1_36_0 myself using a default configuration other than telling it where to put the output libs. I have ensured that I am linking against and including headers from 1_36_0, and have also made a clean build.  Is there anything else I should try?

Thank you,

This is my code snippet that uses boost::filesystem:

//Create Directory if it does not already exist.
      if(!boost::filesystem::exists(reportFilePath))
      {
            cout << "output path: " << reportFilePath << " did not exist, which may indicate a different configuration than was intended, creating directory now." << endl;
            try
            {
                  boost::filesystem::path path(reportFilePath);
                  boost::filesystem::create_directory(path);
            }
            catch(boost::filesystem::filesystem_error e)
            {
                  cout << "Error: " << e.what() << endl;
            }

      }
