Hi Ondrej,

I guess that you are getting this error when you try to construct an instance of your genericsingleton<> class. I don't believe that you will be able to do this because your base class has a private constructor. I suppose if you explain what your purpose is (by deriving from singleton_pool) then someone might be able to suggest a solution for you.
