In the unlikely event anyone is still using -fconcepts in C++17 mode, they can either fix their code to work with C++20 concepts or adjust the compiler flag. It still ICEs with -fconcepts-ts -std=c++11 But I'm not surprised that combination doesn't work, the Concepts TS is supposed to be used with C++17. ^ permalink raw reply [flat|nested] 5+ messages in thread
