'boost :: detail :: variant :: visitation_impl': aucune des deux surcharges ne peut convertir tous les types d'argument

Question

Je ne suis pas capable de construire deux de mes projets avec Boost libraries 1.61.0 et Visual Studio 2015 Update 3

Ces projets étaient très utiles pour les années avec diverses combinaisons de versions de Visual Studio et de Boost, et je n'ai rien changé dans mon code, excepté la mise à jour des bibliothèques Visual Studio et Boost.

L'erreur que je reçois avec ces deux projets est:

'boost::detail::variant::visitation_impl': none of the 2 overloads could convert all the argument types 

Dans ces deux projets, je ne directement à partir de mon code variante non utilise boost ::. Dans un cas, il semble que boost :: variant soit utilisé à partir de boost :: signals2 (que je n'utilise pas directement depuis mon code) et dans les autres cas, boost :: variant est utilisé depuis Cpp-Netlib 0.11.2.

Voici les parties pertinentes des journaux de sortie de ces deux projets:

Est-ce un bogue dans les bibliothèques Boost?

Answer 1

Il semble que vous ayez une installation Boost cassée. Conservez-vous plusieurs versions de Boost? Il existe plusieurs exemples de Boost 1.61.0 et Visual Studio 2015 mise à jour 3 qui fonctionnent ensemble avec succès sur le Web, though this one does say there are some issues with the new SFINAE feature.

Essayez de supprimer les anciennes installations Boost et effectuez une installation propre de Boost 1.61.0 from the Boost distribution.

Il est également possible que Visual Studio ait été corrompu lors de l'installation ou de la mise à jour, mais j'ai rencontré moins de ces types de problèmes.
