[program_options] linking error with example
Hi, I have problems starting out with the program_options library. Looking at the tutorial, I wanted to try out the first example metioned, first.cpp (which is located in boost_1_41_0/libs/program_options/example). But there seems to be some linking error. I try to compile it by g++ -I ~boost_1_41_0 first.cpp -o first ~/boost_1_41_0/stage/lib/libboost_program_options.a But then I get a strange error: /tmp/ccDB6KSC.o: In function `boost::program_options::basic_command_line_parser<char>::extra_parser(boost::function1<std::pair<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::allocator<boost::function_base> >)': first.cpp:(.text._ZN5boost15program_options25basic_command_line_parserIcE12extra_parserENS_9function1ISt4pairISsSsERKSsSaINS_13function_baseEEEE[boost::program_options::basic_command_line_parser<char>::extra_parser(boost::function1<std::pair<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::allocator<boost::function_base> >)]+0x27): undefined reference to `boost::program_options::detail::cmdline::set_additional_parser(boost::function1<std::pair<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::allocator<boost::function_base> >)' collect2: ld returned 1 exit status What am I doing wrong?

Unless you insist on linking statically, try export BOOST_INC=~/boost_1_41_0 export BOOST_LIBS=~/boost_1_41_0/stage/lib g++ -I $BOOST_INC first.cpp -o first -L$BOOST_LIBS -lboost_program_options HTH Christoph

I tried it - seems to compile ok, but when I try to run the program, I get "error while loading shared libraries: libboost_program_options.so.1.41.0: cannot open shared object file: No such file or directory" But the library is there... Best, Katharina

Try adding -R$BOOST_LIBS to the link line. This should include a runtime path to be looked when loading the library. :-)

Hi, You may also add the boost libraries directory to your LD_LIBRARY_PATH via export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$BOOST_LIBS Regards Tobias On Monday 18 January 2010 07:07:25 pm Rangarajan, Kumar wrote: program, I

Hmm, from that I get g++: unrecognized option '-R/home/username/boost_1_41_0/stage/lib'... But anyway it worked with Tobias' solution now. Best, Katharina
