What am I doing wrong? I get error 'boost::program_options::typed_value<T> *boost::program_options::value(T *)' : expects 1 arguments - 0 provided class options { public: unsigned int _option1; int _option2; void parse_options() { boost::program_options::options_description config; config.add_options() ("set1", boost::program_options::value<&_option1>()->default_value(200), "seting 1") ("set2", boost::program_options::value<&_option2>()->default_value(300), "seting 2"); } }; Thanks for help
Hi there, change the template parameter to the real type. program_options::value<&_option1>() ----->>> program_options::value<unsigned int>() That's it, Christian On 3/7/07, Aljaz <aljaz.fajmut@siol.net> wrote:

Hi, it should be: boost::program_options::value<unsigned int>(&_option1)->default_value(200), "seting 1") -- Regards, dave
If I do: config.add_options() ("set1,s", boost::program_options::value<unsigned int>(&_option1)->default_value(20), "seting 1"); it will compile.. But when I run it I get assertion: Assertion failed: n == name.size()-2, file C:\...\boost\boost_1_33_1\libs\program_options\build\../src/options_description.cpp, line 118 If I remove ',s' from the function names, it seems to work ok.. It this a bug? Or am I missing something? Thanks for help again Best regards

Would you mind posting a complete program that exposes this behaviour? Generally, a complete program is preferred for all bug reports against program_options, and I believe authors of other libraries prefer that too, as code snippets are neither compilable nor debuggable. - Volodya
Hey Vladimir I attached the whole code that does a crash.. Please take a look and let me know Aljaz

("timeout,to", boost::program_options::value(&_timeout)->default_value(3), "desc 2"); Here, "to" is invalid. The part after "," is supposed to be short option name, which is supposed to be a single letter. It is presently not supported to have several long option spellings. - Volodya
