Bug ID: 80994
Summary: Misleading error message for missing template keyword
Product: gcc
Version: 7.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: eugene at hutorny dot in.ua
Target Milestone: ---
The example below fails to compile with error
error: invalid operands of types '<unresolved overloaded function type>' and
'int' to binary 'operator<'
which seems to be misleading. A message like 'template keyword needed' would be
much more informative.
template<int count>
struct zoo {
template<int ID>
int bar(char in);
};
template<typename ... L>
class foo {
public:
foo();
inline int bar(char chr) {
return fos.bar<0>(chr); // must be: return fos.template
bar<0>(chr);
}
zoo<sizeof...(L)> fos;
};
int main() {
foo<int, char> tar;
return tar.bar(' ');
}
