Bonjour,

#include "CImg.h"
#include <iostream>
 
using namespace cimg_library;
 
int main()

Si je commente la ligne <iostream>, la compilation se déroule sans soucis !?

J'arrive à utiliser cimg et iostream séparément, mais pas en même temps dans le même programme !!! Bizarre, non ?

Mes recherches de solution n'ont rien donné. J'ai réinstallé Command_Line_Tools_macOS_10.11_for_Xcode_8.2 sans plus de succès
Pour info, je suis sous OSX el capitan, j'utilise X11 pour l'affichage. Je n'utilise pas XCode, mais directement g++ dans le terminal.

Je pense que ça doit être quelque chose de simple, mais quoi ??

Merci par avance pour toute réponse.

Je me réponds à moi-même... mais aussi pour celles ou ceux qui auront passé de leur temps pour lire mon post précédent.

J'ai trouvé de manière empirique une solution à mon soucis de compilation. J'utilise la commande suivante :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

g++ -std=c++14  -I/usr/X11R6/include -L/usr/X11R6/lib -lX11 test_cout.cpp -o test_cout
