--- Comment #3 from Petr Pisar <ppisar(a)redhat.com> ---
As described in
<http://www.scoberlin.de/content/media/http/informatik/gcc_docs/ld_3.html#...;:
When you have multiple definitions of a given symbol, there needs to
be some
way to specify a default version to which external references to this symbol
will be bound. You can do this with the `foo@(a)VERS_2.0' type of `.symver'
directive. You can only declare one version of a symbol as the default in
this manner; otherwise you would effectively have multiple definitions of
the same symbol.
At most one default version of a symbol makes sense.
The old libmysqlclient.so.18 declares only libmysqlclient_18 as the default:
mysql_read_query_result@libmysqlclient_16
mysql_read_query_result@@libmysqlclient_18
while the new libmysqlclient.so.18 declares both versions as default:
mysql_read_query_result@@libmysqlclient_16
mysql_read_query_result@@libmysqlclient_18
I think this is the reason why newly built libmysqlclient.so.18 application
selects libmysqlclient_16 instead of the libmysqlclient_18.
I still don't understand why dynamic linker cannot found the libmysqlclient_16
versioned symbol in the library.

Worth mentioning that there is one difference between mariadb 10.1.8 and
10.1.11 that 10.1.8 was built with 5.2.1 and 10.1.11 is build with gcc-6.0.0.
Can this be the cause?

I'd like to emphases importance of the ldd's "-r" option. The problem
with
mariadb is not a soname, but symbol names. While plain "ldd" resolves only
sonames, it succeeds, but "ldd -r" fails on resolving the symbols against
mariadb library.

--- Comment #10 from Honza Horak <hhorak(a)redhat.com> ---
I've build the same srpm in F23 and F24 and then ran `objdump -T
libmysqlclient.so.18.0.0` and this is the difference:
F23: (libmysqlclient_16) mysql_info
F24: libmysqlclient_16 mysql_info
For libmysqlclient_18 versioned symbols it is the same.
I'm not sure much I understand it, my interpretation is the libmysqlclient_16
is not necessary in F23, so there are both, unversioned and versioned variant
of mysql_info symbol, while in F24 there is only versioned.
The fact that same SRPM produces different output on F23 and F24 means the
difference is in the toolchain. Jakub, can you tell us what changed in gcc 6 in
regards the symbol versioning? Or even better, give us some guidance where this
needs to be fixed?
