the program does not recognize smart pointer

Question

Regarding the use of shared_pointers in a c++ program, I have declared the #include <memory> and then called upon the following std::shared_ptr<int>(new int(5)) it refuses to compile saying that

error: 'shared_ptr' is not a member of 'std'

or alternatively

Symbol 'shared_ptr' could not be resolved

Can anyone tell me why this is happening? from what i read, shared point should be defined in std or boost libraries and i have tried them both

Answer 1

std::shared is a C++11 feature.

You must have a compiler supporting this.

For example with GCC you should add -std=c++11 or -std=gnu++11 .

If you don't have C++11, you can also use boost::shared_ptr .
