g++. _GLIBCXX_NODISCARD je nejspíš atribut [[nodiscard]], _GLIBCXX20_CONSTEXPR je constexpr. Našel jsem třeba nějaký náhodný zdroják, kde (CTRL+F _GLIBCXX20_CONSTEXPR):
#ifndef _GLIBCXX20_CONSTEXPR # if __cplusplus > 201703L # define _GLIBCXX20_CONSTEXPR constexprTakže je otázka, proč ty tam tyhle definice nemáš (i když jinde se tam používají) a kompilátor tomu nerozumí. Zkus
g++ prostě přeinstalovat (a případně předtím ještě promazat ty hlavičkové soubory).
Diky moc, toto nakoniec nepriamo pomohlo.
Preinstalovat g++ nepomohlo - ale mas dobry postreh a vsimol si si, ze mam premiesane hlavickove subory. Tak som odinstaloval libgcc-8-dev a libgcc-7-dev (a vsetko, co na tom zaviselo) a kompilacia uz ide.
