Wt

Hi guys,

I have to make a web application that needs user authentication using wt-3.3.5.

The user's information are stored into a Mysql database table with only 2 fields:

- name varchar(255) (which is the primary key)

- password varchar(255) (which is the md5 of the password)

I wrote the following classes:

- AdminUser which represents the user

- MyUserDatabase a subclass of Wt::Auth::AbstractUserDatabase

- MySession a subclass of Wt::Dbo::Session

• MyApplication which is the view.
  The class AdminUser has 2 public fields of type std::string: name and password.
  When I compile and link all together I got this error:

0x20): undefined reference to `Wt::Dbo::Impl::ParameterWt::WString::clone() const'

MyUserDatabase.o:(.rodata._ZTVN2Wt3Dbo4Impl9ParameterINS_7WStringEEE[_ZTVN2Wt3Dbo4Impl9ParameterINS_7WStringEEE]+0x28): undefined reference to `Wt::Dbo::Impl::ParameterWt::WString::bind(Wt::Dbo::SaveBaseAction&)'

collect2: error: ld returned 1 exit status

make: * [myauthapp] Error 1

Does anybody have a suggestion?

What is the right programming schema in order to make a personal authentication procedure (not that one explained in the examples) ?

Thanks in advance

Stefano
