unknown variable error: innodb_adaptive_hash_partitions

Hi,
I can’t start the latest Percona server downloaded from Launchpad(source code) with this option,
–innodb_adaptive_hash_partitions=8
Am I missing something here ?
Thanks,
Hiromichi

Did you get Percona xtradb or Percona Server? You need Percona Server 5.5.8-20.0 or newer.

Hi gmouse,
Thank you for your reply.
I got Percona-Server-5.5.19-rel24.0 which is the latest source from Launchpad.
Thanks,
