Ho fatto qualche ricerca, tutte le risposte sembrano suggerire l'uso di clang ++ invece di clang (o piuttosto g ++ al posto di gcc), che è quello che ho fatto in il primo posto. Eppure, il problema persiste, sia conErrore di linker misterioso "riferimento non definito a` __gxx_personality_v0 '"utilizzando clang in cygwin
clang++ -Wall -std=c++11 -o test.exe test.cpp A.cpp B.cpp etc.cpp
o
clang++ -lstdc++ -Wall -std=c++11 -o test.exe test.cpp A.cpp B.cpp etc.cpp
La compilazione e linking funziona bene con g ++ in Cygwin.
g++ -Wall -std=c++11 -o test.exe test.cpp A.cpp B.cpp etc.cpp
Aggiornamento:
Ecco le informazioni durante il collegamento. Clang sta provando ad usare gcc per il collegamento, piuttosto che per g ++? In tal caso, perché non flag -lstdC++ e -lsupC++ come suggerito di seguito, funzionano?

Ranera nello stesso problema, e sfortunatamente, sto usando 'throw' nel mio codice, quindi' -fno-exceptions' non funziona :( – Deqing
Sì, è quello che stavo usando, ma se è necessaria un'eccezione, allora ... – CloudyTrees
