Issue compiling c++ source

Question

I have a problem compiling a C++ program and I tried to find the issue and solve it but currently I wasn't able to find the source of the problem. I will appreciate if someone give me a hand :)

The error given is: (compiling under Centos 6.3 with gcc 4.4.7)

Yeah, it's a long piece of code.

Answer 1

You can specifi the flag using -std=c++11

Answer 2

According to this site, std::shared_ptr was introduced in C++11.

Compiling C++11 with GCC requires it's version 4.7 or later.

Note that MistCore is based on the TrinityCore, that instead of using a C++11 specific define named AuraPtr uses a simple Aura* pointer. Reverting this to the original state should work just as it used to in the original project.

You can simply edit /src/server/game/SharedPtrs/SharedPtrs.h and undo the need of std::shared_ptr by replacing the defines with simple pointers. No guarantee that it will solve all problems though. Exemple.
