}
int main(int argc, char* argv[])

}
je courais undefined essayé de compiler ce programme, et a ces erreurs:erreur de fil Boost: Référence

Quelqu'un peut-il me dire pourquoi je reçois cette erreur?
Ressemble boost n'est pas installé sur votre système – riwalk
mais mon '#include #include #include using namespace std; en utilisant l'espace de nommage boost; int main() { \t chaîne str1; \t cin >> str1; \t // chaîne str1 ("bonjour monde!"); \t to_upper (str1); \t cout << str1; return 0; } 'fonctionne parfaitement –

Je l'ai trouvé J'ai besoin d'installer le paquet libboost-thread dans ubuntu – lal
