> In 5.5.35 (I think) the TokuDB plugn was added to MariaDB but I had
> issues getting it build 100% correctly and I eventually dropped it
> (added build parameter -DWITHOUT_TOKUDB=true), as getting MariaDB in

> the code that builds the plugin does not seem to correctly detect the
> CPU features. It seems to read the values from the build machine and
> not the inputted target values (in a cross-compile situation).

> This works well for real and virtual machhines, but it does not seem

> 2) When building TokuDB in Ubuntu (amd64) sbuilder environments
> something in crashes in the 'toku_os_get_processor_frequency'
> function. For this too, could you investigate the sbuilde chroot
> environment and figure out what goes on and how to fix it?
>
> Issue 2 has a bug report with the (a bit messy) debugging history
> documented: https://mariadb.atlassian.net/browse/MDEV-5618

>
> Both of these issues requires learning a bit about sbuilder CPU
> things, so I assume it is most efficient if the same persons looks
