shared_mutex C++11 implementation

Question

I have found the answer from HowardHinnant in this thread. C++11 equivalent to boost shared_mutex

Unfortunately it seems to make use of the following macro which the Microsoft compiler (VS2015 x64) does not seem to support and the code needs to be C++11 and cross-platform.

_LIBCPP_BEGIN_NAMESPACE_STD
_LIBCPP_END_NAMESPACE_STD

I have tried to change it to just

namespace std{
...
}

Then the compiler complains with the following message.

Severity Code Description Project File Line Column Source Suppression State Tool Error C2244 'std::unique_lock<_Mutex>::unique_lock': unable to match function definition to an existing declaration shared_mutex_test c:\\documents\\visual studio 2015\\projects\\shared_mutex_test\\shared_mutex.hpp 1217 1 Build

Question , how to solve this. I need shared_mutex / shared_lock functionality and I have to be C++11 compliant. We have decided not to bring in a bigger library like Boost, hence if I could get HowardHinnant's implementation to work cross-platform it would be the optimal solution.

Many thanks.

Ps. I have not yet got a reputation high enough to comment on closed questions, hence I was forced to open up this new thread. Feel free to move it into the other thread.

Answer 1

Solved by just removing all code that failed. It seems it interfered with the available c++11 implementation of unique_lock. Since I can use C++11 I did not need that part of the code.

To fully solve it the complete unique_lock class probably needs to be implemented.
