Msys2 et Clang sous Windows: fichier iostream introuvable

Question

J'ai suivi ce tutoriel (here) pour que Clang fonctionne sur Windows. Je choisis le chemin pour installer clang en combinaison avec msys2.

Après avoir suivi toutes les instructions que j'ai écrit le programme simple:

#include <iostream> 
using namespace std; 

int main() 
{ 
cout<<"Hello, World!\n"; 
return 0; 
} 

Après avoir compilé avec: clang ++ Helloworld.cpp de Helloworld.exe std = C++ 14

Je reçois l'erreur :

*Helloworld.cpp:2:10: fatal error: 'iostream' file not found,

1 error generated.*

Ajout -v dans la ligne de commande je reçois:

Comment puis-je obtenir le système iostream trouver? J'ai lu quelque chose à propos de, que vous devez pointer vers les en-têtes mingw dans clang/lib/Frontend/InitHeaderSearch.cpp. Je n'ai pas pu trouver le fichier InitHeaderSearch.cpp sur mon ordinateur.

Merci pour votre aide.

Answer 1

En raison de erreur dans le script de compilation des dépendances sont manquantes.

L'installation du package gcc (mingw-w64-i686-gcc pour 32 bits et mingw-w64-x86_64-gcc pour 64 bits) les tirera.
