()->notifier(boost::bind(&config_class::my_function, this)), "include

Thanks a lot for help! I have no idea why the following code crashes my MSVC optimizing compiler: class config_class { public: void read_config() { po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("include-path,I", po::value< vector<string> path"); } void my_function(vector<std::string> str) { } }; Any idea?

Hello

I have boost.program_options implemented inside a config class.

I want to call function (my_function) that is a member of config class for specific option (with notifier call).

class config_class { public: void read_config() { po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("include-path,I", po::value< vector<string>

...

()->notifier(&config_class::my_function), "include path"); }

void my_function(vector<std::string> str) { }

Don't pass vector by value. Further, the notifier method is documented thusly:

typed_value * notifier(function1< void, const T & > f) ; Specifies a function to be called when the final value is determined.

So you better make the parameter const -- you won't be able to modify it anyway.

...

};

This wont compile and will give error for ..>()->notifier(&config_class::my_function)...

error C2064: term does not evaluate to a function taking 1 arguments

What am I doing wrong?

You are passing function with two parameters ("this" and "str") where a function taking one parameter is expected. Use:

boost::bind(&config_class::my_function, this)
