a question about switch()

[jalqadir]

In my program I have the following statements

void Person::setTitle(const Glib::ustring& str) {
switch ( str ) {
case "None" : {
title = title_t::None;
break;
}
case "Dr" : {
title = title_t:r;
break;
}
.......
case "Rabbi" :{
title = title_t::Rabbi;
break;
}
case "Shaykh" :{
title = title_t::Shaykh;
break;
}
default : {
title = title_t::None;
break;
}
}// switch
}//Method

when compiling I get an error code that reads:
==== error: switch quantity not an integer ====
Which is true, but according to

http://newdata.box.sk/bx/c/htm/ch07.htm#Heading54

the error is unwarranted, since the parameter received by the method
and later on given to the switch statement for scrutiny is a valid C/C+
+ statement [setTitle(const Glib::ustring& str)]

Can anyone shed some light to this problem?

Your aforementioned source is distributing misleading informations. The
condition expression over the switch statement has to be of integral or
enumeration type or a class type with a single conversion to an
integral or enumeration type and the label expressions have to be
integral constant expressions. No character literals, structs, doubles
or the alike.

That's putting it mildly. It's full of a lot of partial
information, and very, very dated. To be avoided.
