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 `boost::program_options::options_description::m_default_line_length'

...

and so on
