Subject: Re: [boost] Define to test for deprecated std::auto_ptr
On Tue, Dec 30, 2014 at 7:31 AM, Fletcher, John P
I have some tests which are throwing up std::auto_ptr as deprecated with C++11.
Is there a define that can be tested for in user code so that I can switch to std::unique_ptr when it is available? Something like this:
#ifdef BOOST_NO_CXX11_UNIQUEPTR // use auto_ptr #else // use unique_ptr #endif
Is there a general flag for C++11 or C++14 or is it all done on particular features?
__cplusplus may be helpful. Look at regression tests www.boost.org/development/tests/develop/developer/config.html config_info to see how it is defined for various compilers.

I have found a test. It is BOOST_NO_CXX11_SMART_PTR and it is set by the standard library in use. On test at the moment. Thanks John
