Pourquoi ai-je des erreurs lors de l'installation de versions précompilées de LAPACK sous Windows?

Question

J'essaie d'utiliser la bibliothèque matricielle Armadillo pour faire des calculs matriciels et il faut BLAS et LAPACK. La documentation Armadillo recommandé d'obtenir les versions précompilées de http://www.stanford.edu/~vkl/code/libs.html

Il existe des fichiers .lib et .dll. Le seul problème est que je ne sais pas comment obtenir Visual Studio (Express Edition 2008) pour reconnaître ces fichiers. J'essaie de les copier dans les répertoires include et lib de Visual C++ C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\ et C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib\, mais cela ne semble pas faire grand-chose car lorsque j'essaie de compiler mon programme, j'obtiens beaucoup d'erreurs de "symbole externe non résolu" qui le disent 'can' t trouvez les fonctions LAPACK.

EDIT:

Voici les messages d'erreur:

"Cell3DXT", "TwoCell3DXT" et "ThreeCell3DXT" sont des cours dans mon propre code. Aussi dans les fichiers LAPACK et BLAS ci-dessus, il y a des fichiers ".exp" - qu'est-ce que ceux-ci et ont-ils quelque chose à voir avec le problème?

Answer 1

J'ai trouvé la réponse à mon problème. Le problème était que je savais que je devais mettre le répertoire contenant le fichier .lib LAPACK dans la liste des répertoires de la bibliothèque (Outils -> Options -> Projets et Solutions -> Répertoires VC++ -> Fichiers de bibliothèque) mais j'ai oublié que je devais aussi Ajoutez-le aux "dépendances supplémentaires" sous Projet -> (Nom du projet) Propriétés -> Lieur -> Entrée.

Answer 2

J'ai eu le même problème, mais je l'ai résolu comme suit:

1. télécharger et extraire le LAPACK (LIB + DLL) et BLASS (LIB + DLL) à partir du site de vainqueur,
2. Ajouter le LAPACK et chemins BLASS à l'éditeur de liens répertoires de recherche, par exemple `projet-> Construire Options-> Rechercher Directories-> linker 'dans code :: Blocks,
3. Ajouter à lapack_win32.lib linker Paramètres,
4. Uncomment` #define ARMA_USE_LAPACK' en [CHEMIN Armadillo] /include/armadillo_bits/config.hpp
