C++ std::shared_ptr usage and information(C++ std::shared_ptr 用法和信息)
问题描述
I am trying to use std::shared_ptr
in my code. I have seen there have been other questions on the subject, but I am still getting a compiler error. Have I got the right version of gcc and setup?
What I have done:
I have tried to compile my code with both headers separately — <memory>
and <tr1/memory>
but still get the errors below in both cases.
The version of gcc I am using is
When I include <memory>
header I use std::shared_ptr
and with the <tr1/memory>
header I use std::tr1::shared_ptr
? Is this correct?
I have set up the shared_ptr as follows:
The error I get is as follows:
when I try the <tr1/memory>
header
Looks like I am not including something correctly. Any ideas?
I know the boost library has shared_ptr
but these libraries are not an option for me at the moment.
EDIT: Just to add, my compiler options are as follows: g++ -O3 -g3 -m32 -fPIC -Wno-deprecated -pthread -m32 Am I missing anything?
P.S. Is there any useful literature on the std smart pointers?
std::tr1::shared_ptr
is part of the TR1 additions to the C++ STL.
With GCC, it is available either through #include <tr1/memory>
(GCC 4.1) or #include <memory>
(GCC 4.3)
