--- Comment #2 from Manuel López-Ibáñez <manu at gcc dot gnu.org> --- (In reply to Eric Gallager from comment #1) > Confirmed that the notes could ease up on the template spew; g++ output is > now: Note that I'm not complaining about the redundant notes listing the declaration of the candidates (which are the subject of a different PR that I cannot find right now). The object of improvement here is: no known conversion from 'vector<Real>' to 'const std::basic_string<char>' versus no known conversion for argument 1 from ‘std::vector<double>’ to ‘const std::__cxx11::basic_string<char>&’ On the latter, gcc is excessively unwrapping typedef.
