Hello,
Im facing a conception problem in my program. I have a statics library (all methods are static, no data member) and I would like to use these methods but I would like to know if I should inherit from this class or an simple include will do ?
I have to use the static library in different class, Ive been told to inherit virtually to have one instance of the library used.

Could you guys give me your opinion ?

Thank you for help
