I am writing a C++ library in Xcode 4.2.
One of my classes won't compile with this error:
attempt to use a deleted function
There is no specific indication what function it's talking about. I don't want to post the class code here, but does anybody have any idea what this error means?
In C++11 you can declare functions as deleted:
struct Foo {
Foo(const Foo &) = delete;
};
Attempting to use such a function is an error. The purpose of doing this is so that, in this example, copy construction of this type is not possible. This is a more direct replacement for the non-copyable trick used pre-C++11.
Also, there are rules in the C++ spec that lead to member functions being implicitly deleted.
The error is telling you that your program attempts to use a deleted function. You'll have to post the error you're getting for more detailed help.
