Bibliothèque cimg - erreur de liaison

Question

J'essaie d'utiliser la bibliothèque cimg. J'ai inclus le fichier CImg.h-header. Mais quand j'essaye de le compiler, j'obtiens une erreur de liaison.

Answer 1

Il agit en ajoutant ces options de compilateur

-L/usr/X11R6/lib -lm -lpthread -lX11 

Answer 2

Vous devez également lier la bibliothèque. Vérifiez les instructions de votre compilateur afin de savoir comment le faire.
