Erreurs de poussée passant de CUDA 4.0 à 8.0

Question

Je tente de mettre à niveau ce projet (https://github.com/ashwin/gStar4D), qui est écrit en CUDA 4.0 à 8.0. Mais je reçois une tonne d'erreurs de compilation charrié sur des lignes comme ceci:

thrust::sort_by_key( orderVec.begin(), orderVec.end(), 
          thrust::make_zip_iterator(make_tuple(_pointVec->begin(), _scaledVec->begin()))); 

Les erreurs sont généralement « erreur: classe « poussée :: tuple_size <> » n'a pas de membre « valeur » », « erreur: type incomplet n'est pas autorisé » ou « erreur: nom suivi de « :: » doit être un nom de classe ou espace de noms »

Toute réflexion sur ce que la question pourrait être?

Answer 1

Comme Robert suggéré ci-dessus, juste besoin d'ajouter à la poussée :: make_tuple:

thrust::sort_by_key( orderVec.begin(), orderVec.end(), 
         thrust::make_zip_iterator(thrust::make_tuple(_pointVec->begin(), _scaledVec->begin())));
