You can use MySQL 8.x.

Follow the below if build failed for MySQL 8.x (MySQL 8.0.22, Ubuntu 20.04 LTS for me).
just replace 'my_bool' by 'int' then rebuild.

Note:
if you use gcc-9 then add "-fPIC" to CFLAGS into 'makefile.inc'.
like this:
CFLAGS := -Wall -Wno-strict-aliasing -Wno-uninitialized -g -rdynamic -std=gnu99 -fPIC
then, rebuild all.

MySQL 8.x: replace "my_bool" by "int"
file: utils/ut_mysql.c
my_bool reconnect = 1; -> int reconnect = 1;

that's it.
this works good for me.

I hope may this helps you.
