Re: [Cppcms-users] What did I do wrong? (tutorial #3)

Hello,

You use functions as &hello::number in dispatcher, but not declare it inside class.
So declare it below "main":
class hello ...
{
...
virtual void main(std::string url);
void number(std::string);
void smile();
void welcome();
};

and write it below as "hello::number", etc. instead "number":

void hello::number(std::string num) {
    int no = atoi(num.c_str());
    response().out() << "The number is " << no << "<br/>\n";
    response().out() << "<a href='" << url("/") << "'>Go back</a>";
}
