Error compiling Visual Studio 2012 C ++ using Boost Signal2

Question

I am using Visual Studio 2012 Ultimate with the following Boost Signals2 code: at https://github.com/cfobel/boost_signals2/blob/master/hello_world_0.cpp It generates the following error:

c:\program files (x86)\microsoft visual studio 11.0\vc\include\xmemory(348): error C4996: 'std::_Uninitialized_copy0': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators' 1> c:\program files (x86)\microsoft visual studio 11.0\vc\include\xmemory(333) : see declaration of 'std::_Uninitialized_copy0' 1> c:\libraries\boost_1_52_0\boost\signals2\detail\auto_buffer.hpp(192) : see reference to function template instantiation '_FwdIt std::uninitialized_copy<I,boost::variant<T0_,T1>*>(_InIt,_InIt,_FwdIt)' being compiled 

Is this code incompatible for Visual Studio 2012 C ++? Is it safe to use? Finally, how do I make the changes as suggested? Thanks

Answer 1

C4996 is a warning about using a feature that has been deprecated. Since you see this as an error, maybe you have the option Treat Warning as Error (/WX) enabled?

The way to disable this is described in the error message itself. Add the _SCL_SECURE_NO_WARNINGS symbol to the project preprocessor definitions.
