Comment corriger Visual Studio 2012 erreur LNK2019: symbole externe non résolu " declspec (dllimport) public: class std:: chaîne de base?

comment corriger une erreur de Visual Studio 2012 LNK2019: symbole externe non résolu " _ _ _ declspec (dllimport) public: class std:: basic_string?

j'ai compilé une solution contenant un exe et plusieurs projets de lib statique sur lequel l'exe dépend bien avec Visual Studio 2008. Les bibliothèques statiques suivants:

  • TCL: tcl84tsx.lib
  • wxWidgets: wxbase.lib
  • zlib.lib
  • ws2_32.lib
  • xerces-c_2.lib
  • émanent de la recherche SNMP: subagent.lib,de l'agent.lib,émanent.lib, pack.lib, mibtable.lib, devkit.lib
  • etc.

j'ai chargé la solution dans Visual Studio 2012 et j'ai compilé tous les projets de la solution mais quand j'essaie de lier l'exe, je reçois des erreurs sur les symboles non résolus pour des trucs dans la bibliothèque standard C++ comme la sortie dessous.

j'ai trouvé beaucoup de gens avec des symboles non résolus comme celui-ci mais aucun des correctifs ne fonctionne pour moi. Les correctifs que j'ai essayés jusqu'à présent comprennent

  • mise à jour du projet EXE en ajoutant manuellement des références aux projets lib statiques dont dépend le projet exe
  • Basculement de la "traiter wchar_t intégrés de type" linker option

sortie de Visual Studio 2012 linker...

propriétés->c/c++->Langue, j'ai mis en traiter wchar_t que construit dans le type de Pas de et il a résolu mon problème.

si vous avez déjà essayé les options suivantes:

  • mise à jour du projet EXE en ajoutant manuellement des références aux projets lib statiques dont dépend le projet exe
  • Basculement de la "traiter wchar_t intégrés de type" option

essayez de configurer votre projet x64 en suivant les étapes suivantes:

  • clic Droit sur Solution 'ProjectName'
  • Sélectionner Configuration Manager...
  • Changer platform du projet que vous tentez de relier .fichier lib x64Win32 (ou vise versa)
  • Reconstruire la solution

ceci a effectivement résolu mon problème. Je ne savais pas si ma lib externe était compilée pour 32 bits ou 64 bits.

répondu Anvesh Yalamarthy 2017-06-08 12:24:00

même moi j'ai fait face à ce type d'erreurs dans visual studio. La raison de ces erreurs,

1) Vous avez pu inclure plusieurs bibliothèques qui sont en conflit les unes avec les autres. Parfois,une classe dans une bibliothèque peut entrer en conflit autre classe dans une autre bibliothèque.

2) vous auriez pu inclure les bibliothèques des répertoires. Vérifiez à nouveau le chemin des bibliothèques.

3) Vous devez spécifier les bibliothèques et les fichiers d'en-tête (si vous devez inclure) dans le les propriétés du projet. Vérifiez encore une fois si les chemins sont corrects.
