Boost C++ Libraries: Ticket #11622: std::auto_ptr is deprecated

anonymous — Mon, 07 Sep 2015 09:30:42 GMT

It's really driving me nuts.

The only way I'm keeping sane, is to use this compile flag:

-Wno-deprecated-declarations

owner, component changed

owner changed from Frank Mori Hess to Peter Dimov
component signals2 → smart_ptr

These warnings aren't coming (directly) from Boost.Signals2 they are coming from the smart pointers library.

Should be fixed in https://github.com/boostorg/smart_ptr/commit/df904965833dcf1bf2eb4d7d1416369dd806e092

Compiling Zcash with -Werror using Boost 1.62.0 (which includes the above fix), I still get this error:

It seems that the fix applied to the smart pointers library needs to be expanded to all libraries that use auto_ptr.

still an issue in the 1.64.0 Release.

Peter Dimov — Sat, 29 Apr 2017 17:25:28 GMT

The Spirit issue, or something in smart_ptr?

libc++ v5 (available in AUR on ArchLinux) does not have auto_ptr header anymore, if compiling with flag -std=gnu++1z, so this is now a compile error, not a warning anymore:

boost/include/boost/ptr_container/ptr_sequence_adapter.hpp:223:45: error: no type named 'auto_ptr' in namespace 'std'
        explicit ptr_sequence_adapter( std::auto_ptr<PtrContainer> clone )
                                       ~~~~~^

/usr/local/include/boost/statechart/processor_container.hpp:67:16: warning: 'template<class> class std::auto_ptr' is deprecated [-Wdeprecated-declarations]

typedef std::auto_ptr< processor_base_type > processor_holder_type;

I just hit this issue whilst trying to use Boost 1.66 with C++17.

But from what I can see the C++17 issue has been fixed since 1.66 in b805b3c.

I don't know how that affects the original deprecated warnings issue, though it looks as though there are several more commits about this in the last couple of months.

To anyone having problems with the warnings: can you work around the problem by specifying the Boost include using -isystem?

I'm seeing these warnings in boost.locale within 1.66, using gnu g++ version 5.4.0.

I'm getting these errors when trying to install R dependencies for lubridate and forecast....
