I wrote a few lines of code just for start with a library of boost (program_options). Before I did it I had built boost library as prescribed and *.a and *.so 
files were created in my /home/krzysztof/Documents/Projects/boost/lib directory. However, compilation fails because of undefined references of some 
external symbols which belongs to program_options library. Could anyone help me with it? Below, there is the code and g++ output.
(Linux 64b, Qt Creator and Code::Blocks used as IDE)

#include "boost/program_options.hpp"

using namespace boost::program_options;
using namespace std;

int main(int argc, char *argv[])
{
    options_description opd;

    opd.add_options()
            ("help","Display help")
            ("input_file,if",value<string>(),"Specifies input file")
            ("fet_file",value<string>(),"definitions file")
            ("output_file,of",value<string>(),"file after edition");
}

g++  -o fetxedit main.o    -L/usr/lib -L/home/krzysztof/Documents/Projects/boost/lib -lQtCore -lpthread 
main.o: In function `main':
/home/krzysztof/Documents/Projects/fetxedit-build-desktop/../fetxedit/main.cpp:8: undefined reference to

...
and so on
