error: use of deleted function

Question

I\'ve been working on some C++ code that a friend has written and I get the following error that I have never seen before when compiling with gcc4.6:

error:          


        

Answer 1

You are using a function, which is marked as deleted.
Eg:

int doSomething( int ) = delete;

The =delete is a new feature of C++0x. It means the compiler should immediately stop compiling and complain "this function is deleted" once the user use such function.

If you see this error, you should check the function declaration for =delete.
