None of the examples there uses anything different from int. You'd
better use a textbook on the language to read on the restrictions of
switch, not some bogus information in a document focuses on some
library. The error is perfectly ok, so this is not a gcc problem.
You could use some map to map the strings to values to avoid the
if..else if...else if cascade.
Maybe like the following.
typedef std::map<Glib::ustring&, title_type> strToTitleType;
strToTitleType strToTitle;
...
...initStrToTitle() {
strToTitle["None"] = title_t::None;
...
strToTitle["Shayk"] = title_t::Shayk;
}
....
void Person::setTitle(const Glib::ustring& str) {
strToTitleType::const_iterator sit = strToTitle.find(str);
if (sit == strToTitle.end())
title = title_t::None;
else
title = sit->second;
}
