Arch Linux

I did some research and it seems to me that this problem has already been described in several places:
https://bbs.archlinux.org/viewtopic.php?id=209560
https://bugzilla.redhat.com/show_bug.cgi?id=1312578
https://bugzilla.redhat.com/show_bug.cgi?id=1312151
https://sourceware.org/bugzilla/show_bug.cgi?id=19698

A possible fix is supposedly to update binutils to a more recent version: https://sourceware.org/bugzilla/show_bug.cgi?id=19698#c21
and recompile mariadb.

However I have not jet been able to recompile mariadb because of an error when checking the compiler capabilities although gcc 5.30 is installed:
$ LANG=C c++ -v
Using built-in specs.

Steps to reproduce:
recompile any binary that is getting linked to libmysqlclient.so.18, e.g. mysql-python (https://www.archlinux.org/packages/extra/x86_64/mysql-python/) using the current mariadb and binutils packages:

I'm thinking this has to be a local problem. /usr/lib/python2.7/site-packages/_mysql.so from the repo has no version references outside of GLIBC.

Edit: nevermind, objdump mislead me here.

Can you give us the output of `readelf --dyn-syms /usr/lib/libmysqlclient.so.18 | grep mysql_fetch_row`?

In mine, the symbols exist. I am seeing the issue described in the binutils bug report about two symbols both being default, but I don't get the errors from ldd that you do.

I thought I had pulled this fix, but our binutils build is from 24th of Feb and this was pulled on the 26th. I'll make a new build now.

binutils rebuild with the bug fixed in [testing]. I assume mariabd needs a rebuild.
