If the mutex is a member variable, then in the const method, it is a
const mutex. scoped_lock requires a non-const mutex. This is what is
causing the error.
Declare the mutex as mutable so it appears as non-const even in const
members. (I don't know if this is the preferred way, but it is the way
I currently use).
It works if the mutex is declared in the .cpp because it is not part of
the class, and therefore isn't const when accessed inside a const method.
