How to "activate" c++11 standard in visual studio 2010?
I am new to c++ programming and I need to use the Thread class in my VS 2010 project. I've found this reference, but when I try the following:
#include <thread>
VS 2010 obviously tells me 'Error: cannot open source file "thread"'. I understand that I need to "activate" c++11 standard somehow. I do not even know where to start.
So what should I do to use () c++11 standard in visual studio 2010?
Solution 1:
std::thread is obviously not in VS 2010. I think it was added with VS 2012, which is also supported by this question and answer. Is there any specific reason you're using 2010 rather than the latest version, 2013, which supports far more part of C++11?
Also to note: Contrary to GCC, MSVC doesn't have an "opt-in" for newer standards. It just supports them out of the box as far as implemented.
Solution 2:
The Visual C++ compiler is not fully C++11 compatible. C++11 features had been supported since Visual Studio 2010 and added incrementally. Not even the next version of Visual Studio will provide full C++11 compatibility. A matrix of C++11 features available in different versions of Visual Studio can be found here:
- C++0x Core Language Features In VC10: The Table
- C++11 Features in Visual C++ 11
- C++11/14 STL Features, Fixes, And Breaking Changes In VS 2013
Solution 3:
C++11 is enabled by default, but there is not many features implemented in VS 2010. C++11 standard library is missing many headers in VS 2010. Here is a comparison of a last few VS releases regarding the C++11 support.
