Vous n'avez pas défini toutes les fonctions déclarées dans BaseProperty. Vérifiez qu'il y a bien le code pour les constructeurs, le destructeur, et la fonction OpenMesh::BaseProperty::stats(std::basic_ostream<char, std::char_traits >&) const

Par hasard, vous n'essayeriez pas d'utiliser une classe abstraite ?

open.o: In function `void OpenMesh::BaseProperty::check_and_set_persistent<OpenMesh::VectorT<float, 3> >(bool)':
open.cpp:(.text._ZN8OpenMesh12BaseProperty24check_and_set_persistentINS_7VectorTIfLi3EEEEEvb[void OpenMesh::BaseProperty::check_and_set_persistent<OpenMesh::VectorT<float, 3> >(bool)]+0x39): undefined reference to `omerr()'

Ça paraît plutôt clair, il ne trouve pas omerr().
