[Boost-users] link fail against boost_filesystem on FreeBSD 5 with gcc 3.3.3

It's my first time using boost

I'm using boost 1.30.2 with FreeBSD 5, where gcc version is 3.3.3
following is my code, quite simple

<code>
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/fstream.hpp>
#include <string>
#include <iostream>

namespace fs = boost::filesystem;

const std::string LogFileName = "ggyy";

int main(void)
{       
        fs::ifstream LogFile(LogFileName);

        return 0;
}
</code>

it compiles well, but failed on linking :

<error>
g++  -L/usr/local/lib -lboost_filesystem -o LogParser LogParser.o
LogParser.o: In function `main':
LogParser.o(.text+0x27): undefined reference to `boost::filesystem::path::path(std::string const&)'
LogParser.o(.text+0x51): undefined reference to `boost::filesystem::path::native_file_string() const'
*** Error code 1
</error>

My boost is built from the ports system, and I'm sure I have libboost_filesystem.a and other related boost libraries

so... could someone tell me how to solve this problem ?
