commit 6ea0ec58da1377052f15601db6e09590e09f54bb
Author: Don Lewis <truck...@apache.org>
AuthorDate: Sun Aug 23 10:55:50 2020 -0700
Force Linux builds to use gnu++98 (C++98 + GNU extensions) mode to be
the most compatible with our old code base rather than relying on the
compiler default mode. Compiling in C++11 or newer mode is very noisy
due to deprecation warnings about our use of std::auto_ptr. If the
compiler defaults to C++17 mode or newer, the build would be totally
broken because std::auto_ptr is removed from C++17.
There is an unknown amount of porting effort needed to convert to
std::unique_ptr, which has somewhat different semantics and which is
not available before C++11, which would break building with older versions
of gcc which default to gnu++98 mode.
std::shared_ptr, might be an alternative since there is a BOOST
implementation.
