Erreur de liaison C++ LNK2019

Question

Quelqu'un peut-il m'aider s'il vous plaît à configurer Visual Studio 2005 (si c'est la solution au problème). J'utilise des libs externes et je reçois cette erreur:

Answer 1

Je pense que la bibliothèque que vous importez (hdu.lib) est construit avec une bibliothèque d'exécution différente - soit vous mixez le débogage et libérer les bibliothèques ici ou statique vs DLL runtimes.

Answer 2

Il me semble que vous n'êtes pas lié dans la bibliothèque C++. Si vous faites un clic droit sur les "propriétés" de votre projet, et que vous vérifiez les propriétés de configuration -> Linker -> Input, votre ligne "Additional Dependencies" inclut-elle "libcpmt.lib"?

Answer 3

Cela aiderait si vous pouviez poster les commutateurs de ligne de commande que l'éditeur de liens fonctionne, je veux dire la commande complète.

Il semble que ce libraire hdu dépende de la bibliothèque iostream C++, pouvez-vous vérifier si vos paramètres de lieur spécifient la bibliothèque iostream.
