Hi, I haven't tried yet. I want to do this. Well, Not exactly for Solaris, but OmniOS. Later. When I have some kind of CI/CD infra at home. No one likes to do things manually. Before I'd do that, I need a lot of other things, so this personal project is stalled for another couple of months. Until then, If you need some kind of quick wins, I found this: https://www.opencsw.org/packages/CSWsyslog-ng/ Well, I know it's syslog-ng 3.6.2. But At least a starting point. What I would do: I'd try to re-build 3.6.2 on my own using the same building architecture and environment what opencsw uses. When I have the infra to build 3.6.2 in a reliable way, I'd try to throw in 3.15 into that. If not works, then I'd try to bisect and find the change what brokes the building. When I found that -> fix. Profit. HTH, Gyu
