Hello, I am attempting to parse configuration options from a file using Boost::program_options. I am following the example provided on the website (http://www.boost.org/doc/libs/1_49_0/doc/html/program_options/overview.html#...): variables_map vm; store(parse_command_line(argc, argv, desc), vm); store(parse_config_file("example.cfg", desc), vm); notify(vm); I have included the following related to program_options: #include <boost/program_options.hpp> // Boost Program Options #include <boost/program_options/positional_options.hpp> #include <boost/program_options/parsers.hpp> I have the exact code as above in my program but receive the following error. The program works fine if I comment out the line with the parse_config_file line. Can someone please help me get this working. Thanks, Andrew --- COMPILER ERROR -------------------------- /home/slaughter/Documents/programs/source/common/user_options/user_options.cpp: In member function ‘void SlaughterCommon::User_options::apply_options(int, char**)’: /home/slaughter/Documents/programs/source/common/user_options/user_options.cpp:27:76: error: no matching function for call to ‘parse_config_file(const char [22], boost::program_options::options_description&, bool)’ /home/slaughter/Documents/programs/source/common/user_options/user_options.cpp:27:76: note: candidates are: /usr/include/boost/program_options/parsers.hpp:163:5: note: template<class charT> boost::program_options::basic_parsed_options<charT> boost::program_options::parse_config_file(std::basic_istream<charT>&, const boost::program_options::options_description&, bool) /usr/include/boost/program_options/parsers.hpp:176:5: note: template<class charT> boost::program_options::basic_parsed_options<charT> boost::program_options::parse_config_file(const char*, const boost::program_options::options_description&, bool) make[3]: *** [source/common/CMakeFiles/common.dir/user_options/user_options.cpp.o] Error 1 make[2]: *** [source/common/CMakeFiles/common.dir/all] Error 2 make[1]: *** [source/common/CMakeFiles/test_user_options.dir/rule] Error 2 make: *** [test_user_options] Error 2
