Comment 1 for bug 1372284

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Looks like the check-mk source package embeds a copy of nagios' downtime.h (along with other header files), and that Nagios has updated a struct since then.

Patching Nagios doesn't make sense here, from a distribution perspective. The real fix is to fix check-mk's packaging to use a build dependency on some kind of nagios-dev package which provides the required headers. So this is a bug in check-mk, not in nagios.

This is probably relevant to Debian's check-mk packaging, too. Checking in Debian and reporting there if this bug applies to Debian would be appropriate.
