Boost::Pool - Singleton_pool

[oslu]

Hi,
Is there a way on how to derive a class from pool::singleton_pool class?
Something like:

template<typename T>
genericsingleton  :  boost::singleton_pool<boost::pool_allocator_tag,
sizeof(T)>

If I want to do this I always get this error:

Error    1    error C2248:
'boost::singleton_pool<Tag,RequestedSize>::singleton_pool' : cannot
access private member declared in class
'boost::singleton_pool<Tag,RequestedSize>'    
c:\mycode\boosttest\boosttest\genericsingleton.h    23

Thank you for answer.

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.

Regards, Paul
