Bonjour,

J'essaye de compiler un fichier avec Visual Studio 2005 et j'ai l'erreur suivante quand je compild mon code:

Code X : Sélectionner tout - Visualiser dans une fenêtre à part

error C2593: 'operator +' is ambiguous
   could be 'built-in C++ operator+(int, short)'
1>        or       'built-in C++ operator+(int, int)'
1>        or       'built-in C++ operator+(int, bool)'
1>        or       'built-in C++ operator+(int, float)'
1>        or       'built-in C++ operator+(int, double)'
1>        while trying to match the argument list '(int, itpp::bin)'

voici mon code. J'ai mis mon erreur en gras.
