Fedora is currently two major and one minor release behind on OCE due to the fact that smesh had not been updated to some library/API changes. Secondarily smesh would not build on GCC 6 but that has now been fixed.

I plan to build OCE 0.17.1 and newly released smesh 6.6 in the next day or so.

On a tangent, I was able to figure out required rebuilds with yum/repoquery but I can't seem to find the magic incantation for "dnf repoquery". 

Is there a documented "best practice/known good" command in the wiki and I just can't find it? 

Thanks,
Richard
