Subject: Re: [PATCH] libsupc++: try cxa_thread_atexit_impl at runtime
Date: Tue, 5 Dec 2023 18:15:08 -0500	[thread overview]
Message-ID: <CAGWvnynnp6Z-d4HwMuS9bj2Oph1xD4vSP6irkVNJzjzW9LCOcw@mail.gmail.com> (raw)
In-Reply-To: <CAGWvny=8391BCUZF8eyYgP-NMoWM+qa6Yra6OGVVXuQNuAi9kw@mail.gmail.com>

[-- Attachment #1: Type: text/plain, Size: 540 bytes --]

The error is:

ld: 0711-317 ERROR: Undefined symbol: __cxa_thread_atexit_impl


from the new, weak reference.


Also, earlier in atexit_thread.cc, there is another definition protected by


_GLIBCXX_HAVE___CXA_THREAD_ATEXIT_IMPL


not utilized by the new reference.


Thanks, David
