libdriver_msql.so

[kaniggl]

Hello,

i installed dovecot 2.11.1 on ubuntu
Linux dadd3041 3.16.0-30-generic #40-Ubuntu SMP Mon Jan 12 22:07:11 UTC
2015 ppc64le ppc64le ppc64le GNU/Linux

To make it clear, architecture is PowerPC 64bit
Then i installed dovecot via apt-get. But the file
/usr/lib/dovecot/modules/auth/libdriver_mysql.so
is missing.

So i compiled dovecot myself on this system and got a file
/usr/lib/dovecot/modules/auth/libdriver_mysql.so

Then i restartetd the server and try to do a login via a webmailer
(roundcube), but i get no connection to the database server.

This is found in /var/log/mail.log

broken (disconnected before auth was ready, waited 0 secs): user=<>,

session=<rJpS9AMR9wAAAAAAAAAAAAAAAAAAAAAB>

I know this means it is not a 64bit object but how could i achieve to get
right one?

best regards,
