8. In your function h you have declared that r is a copy of a constant Record -- therefore, you cannot change r or any part of it -- it's constant. Apply the right-left rule in reading it. Note, too, that you are passing a copy of r to the function h() -- if you want to modify r then you must pass a non-constant pointer. void h( Record* r)
c++
So none of your functions match that type. What you want is typedef GUI* (*CreateGUIFunc)( std::string &filepath, int x, int y ); Next, try using the insert member function of the map instead of the subscript operator, that way you can't end up calling the constant version by accident. answered Jun 26, 2010 at 0:44.
Error: Assignment of read-only location in C
Error: Assignment of read-only variable in C. Error: assignment of read-only location occurs when we try to update/modify the value of a constant, because the value of a constant cannot be changed during the program execution, so we should take care about the constants. They are read-only. Consider this example:

Caveat: It is not necessary to put the implementation in the header file, see the alternative solution at the end of this answer.. Anyway, the reason your code is failing is that, when instantiating a template, the compiler creates a new class with the given template argument.

C++ error:Assignment of read-only location
An object of type std::initializer_list<T> is a lightweight proxy object that provides access to an array of objects of type const T. The elements of an initializer_list are always const, and thus *carteRow_iterator is const. If you want a modifiable list of objects, use std::vector or std::array. edited Nov 7, 2015 at 23:12.
