Pourquoi est-ce que je reçois des erreurs d'installer les versions précompilés de LAPACK sur Windows?

Question

Je suis en train d'utiliser la bibliothèque de la matrice Armadillo à faire calcualtions de la matrice et il a besoin BLAS et LAPACK. La documentation Armadillo recommandé d'obtenir les versions pré-compilées à partir de http://www.stanford.edu/ ~ VKL / code / libs.html

Il y a des fichiers .lib et .dll là-dedans. Le seul problème est que je ne sais pas comment Visual Studio (Express Edition 2008) pour reconnaître ces fichiers. J'essaie de les copier dans Visual C ++ include et lib C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\ et C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\lib\, mais il ne semble pas faire quoi que ce soit parce que quand je tente de compiler mon programme, je reçois beaucoup d'erreurs « symbole externe non résolu » qui disent qu'il peut » t trouver des fonctions LAPACK.

"Cell3DXT", "TwoCell3DXT" et "ThreeCell3DXT" sont des cours dans mon propre code. De plus dans les fichiers LAPACK et BLAS ci-dessus, il y a des « fichiers .exp » - ce sont ceux-ci et faire ceux-ci ont quelque chose à voir avec le problème

Answer 1

Je me suis dit 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 bibliothèque (Outils -> Options -> Projets et Solutions -> Répertoires VC ++ -> Bibliothèque de fichiers) mais il a oublié que je devais aussi ajouter aux "dépendances supplémentaires" au titre du projet -> (Nom du projet) Propriétés -> Linker -.> 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. Ajoutez les chemins LAPACK et BLASS à lieur répertoires de recherche, par exemple `Projet-> Construire Options-> Rechercher Directories-> Linker » dans Code :: Blocks,
3. Ajouter lapack_win32.lib à Linker Paramètres,
4. Uncomment `#define ARMA_USE_LAPACK » dans [Armadillo PATH] /include/armadillo_bits/config.hpp
