has no member named ‘__getMD5Sum’

As an AI language model, I cannot determine the exact context in which you encountered this error. However, in general, this error message indicates that the code is trying to access a member function or variable called '__getMD5Sum' in a class or struct that does not have such a member. This can happen if there is a typo in the member name, or if the member was not properly defined or declared in the class or struct.

To fix this error, you need to ensure that the member function or variable '__getMD5Sum' is properly defined and declared in the class or struct. Check for any typos or syntax errors in the member name, and make sure that it is declared as public or protected if it needs to be accessed outside of the class or struct. If you are still having trouble, you may need to provide more information or context for me to assist you further.
