--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This example is from PR 101811
struct X {
void f();
};
template<int i> // this line should not be here
void X::f()
{}
GCC is pretty bad here:
<source>:6:6: error: no declaration matches 'void X::f()'
6 | void X::f()
| ^
<source>:2:10: note: candidate is: 'void X::f()'
2 | void f();
| ^
<source>:1:8: note: 'struct X' defined here
1 | struct X {
| ^
But Clang is no better:
<source>:6:9: error: out-of-line definition of 'f' does not match any
declaration in 'X'
void X::f()
^
<source>:2:10: note: member declaration nearly matches
void f();
^
It seems to give up on noticing why the candidate doesn't match and just says
"nearly matches" as a generic fallback.
To fix this bug will need a list of things to check for. Did it fail to match
because one is cv-qualified and the other isn't? Maybe one is ref-qualified and
the other isn't? Maybe one is a function template and the other isn't? Maybe
the number or type of parameter (or template parameters) doesn't match etc.
