Bibliothèque d'apprentissage automatique OpenCV 2.1

Question

J'ai essayé de compiler le CvEM example de la documentation. J'ai placé le chemin de recherche de bibliothèque à opencv \ lib et également le chemin d'inclusion. J'ai inclus la bibliothèque d'apprentissage machine -lml mais je reveive l'erreur suivante:

undefined reference to CvEM::CvEM()

Si je commente CvEM em_model le code compile:

// CvEM em_model; 
CvEMParams params; 

CvEMParams ne provoque pas une erreur, je pense que les chemins d'inclusion sont ok. Est-ce que quelqu'un sait comment résoudre ce problème?

Si je cours le code dans Visual Studio, il fonctionne parfaitement.

EDIT: Ajout d'autres informations

Mon fichier .pro a les commandes suivantes

INCLUDEPATH += C:/OpenCV2.1/include 

INCLUDEPATH += C:/OpenCV2.1/include/opencv 

LIBS += -L"C:/OpenCV2.1/bin" -lcv210 -lcxcore210 -lcvaux210 -lhighgui210 -lml210 -lcxts210 \-lnetapi32` 

Et ma compilation ressemble à ceci:

recompiler la distribution avec la version de pintes de Moww et ça va marcher.
