thanks, I’ll test on SmartOS.
On my amd64 NetBSD 9_stable machine, tracking pkgsrc head...
For the last 5 or 6 days, I have been unable to build
mysql57-server. The client, and all dependencies seem to build fine.
It builds fine with Clang, but fails with GCC. That's because MySQL forces gnu++03 standard, while gnu++14 is required. I've committed a fix. You can give it a go.
