L'installation d'OpenCV bloquée à [99%] Construit la cible opencv_perf_stitching sans erreur

J'installe donc la dernière version d'OpenCV 3.2.0 et elle est restée bloquée à 99% (même si j'ai passé nproc à -j car cela a pris très longtemps et ma sortie nproc est 24) et je me demande s'il y a une solution car je préfère ne pas l'arrêter. Je ne reçois aucune erreur:

CUDA 8
Python 3.4.3
OpenCV3.2.0
Ubuntu 14.04

eh bien, il s'avère qu'il reste bloqué pendant assez longtemps, puis avance avec succès. N'arrêtez pas l'installation. SOYEZ PATIENT!

J'ai eu le même problème. La commande make -j4 a entraîné le blocage du processus de fabrication à 99%. Contrairement à d'autres utilisateurs plus chanceux, malgré plusieurs heures d'attente et malgré 7,5 Go de mémoire d'échange, mon processus n'a pas été résolu.

Ce qui a fonctionné, cependant, est une suggestion que j'ai trouvée sur cette page Web , qui essayait de construire avec un seul cœur à la place:

make -j1

Cela a pris plus de temps, mais a fonctionné.

Vous devriez augmenter votre swap.

Mon installation se bloquait également jusqu'à ce que j'augmente mon swap. Puis il a terminé. Vous pouvez essayer de le faire temporairement pour voir si cela aide.
