Compilation fails with MariaDB

[foobar26]

Hi,
I tried to compile the latest release (1.9.1) on most recent Ubuntu 18.04.3 LTS with MariaDB (1:10.1.47-0ubuntu0.18.04.1) with libmariadb-dev (3.0.3-1build1), and compilation fails:

I already fiddled around with the mysql.h, but couldn't find a working solution.
Is there anything I can do to prevent the mysql package from being built or to fix this issue?

Thanks in advance,
Frank

And another issue I forgot: initially the build failed because the mysql_config application was missing:

Makefile:27: recipe for target 'local/COMPLETE' failed

For this a workaround was to just do a

ln -s mariadb_config mysql_config

in /usr/bin.

Just another info: release 1.8.0 was building ok.

I tried the same as also on my machine, the build fails (see #284).
But the link is a "dead" link as "mariadb_config" doesn't exist.
Is this available in your installation and with which installation package is it installed (haven't found it with apt search mariadb_config)?

@KanteTaete You can use apt-file search mariadb_config to find out which package provides the file. In my case (Ubuntu 18) it is libmariadb-dev.
