La compilation du noyau CUDA a échoué

J'ai geforce 1070, ubuntu-studio 16.10 et installé CUDA 8 (à partir d'ici: https://developer.nvidia.com/cuda-toolkit ). J'installe également g ++ 5 et crée un lien symbolique

ln -s/usr/bin/gcc-5/usr/local/cuda/bin/gcc

mais quand j'essaie de rendre le modèle dans Blender, j'ai reçu une pile de messages après "Compiler le noyau CUDA". Tous les journaux (exécutés depuis la console)

Comment le réparer? Merci d'avance.

Cela a fonctionné pour moi sur Blender 2.76b (Ubuntu 16.04)

  1. Ouvrez kernel.cu

Sudo gedit /usr/share/blender/scripts/addons/cycles/kernel/kernels/cuda/kernel.cu

  1. Trouvez la ligne qui ressemble à ceci:

/* 5.0 and 5.2 */

#Elif __CUDA_Arch__ == 500 || __CUDA_Arch__ == 520

Cela peut être légèrement différent, mais devrait commencer par #Elif __CUDA_Arch___ ==

  1. Changez cette ligne en: #Elif __CUDA_Arch__ >= 500

Cela permettra à Blender de compiler les nouvelles architectures CUDA. Cela ne fonctionnera peut-être pas comme prévu et vous recevrez probablement des avertissements lors de la première exécution (lors de la compilation), mais vous n'obtiendrez plus l'erreur de compilation. En outre, cela fonctionne pour moi sur Ubuntu 16.04 avec Blender 2.76b et CUDA 8.0

J'utilise Blender 2.78 avec Ubuntu 17.04 et CUDA 8.0:

  • l'installation de g ++ 5 n'a pas fonctionné
  • changer kernel.cu n'a pas fonctionné (Blender 2.78 a déjà le changement)

Mais cela a fonctionné:

  1. Exécutez Blender en mode Sudo avec "Sudo blender". Le rendu avec GPU a chargé les noyaux et le rendu a fonctionné
  2. Ensuite, exécutez Blender normalement (pas de Sudo) et le rendu GPU fonctionne maintenant.

Installer G ++ 5 résout le problème. Veuillez utiliser la commande suivante:

Sudo apt install g++-5
