I have issue with installing "mysqlnd memcache" plugin ( to use with InnoDB Memcached Daemon (having its "/usr/lib/mysql/plugin/") on Ubuntu (Bionic) 18.0.4.

The problem is that the official installation instruction for "mysqlnd memcache" plugin wants "include/libmemcached/memcached.h" to be contained by the directory where is stored. (In addition to use --with-libmemcached-dir=

B) i also need help in understanding this line in official documentation "This (the directory of directory has to contain the include/libmemcached/memcached.h file

Link to Official Documentation.

It seems to me that you are confusing mysqlnd_memcache and
memcached which are completely separate packages.

Anyhow, the mysqlnd_memcache plugin is unmaintained for many years
(last release was 2013-07-17), so it is unlikely to work with
current PHP/mysqlnd versions.  Until a maintainer steps forward, I
suspend this ticket.
