Description Kurt Hindenburg 2021-07-20 23:58:54 UTC 
I build KF5 from current source.  This is the first git change that doesn't build  8540c72b29cc48e9e6ba14807e4e6180e3f62fce which is confusing to me.  I would have assume it as the 2 earlier registry changes that would have caused it: 9901089fd067b361583b165727ff56107dcd3b87 and b8a1f65d07c58f57e83f2a50344a374de137410b

Comment 1 Nicolas Fella 2021-07-21 17:49:38 UTC 
Most likely your gperf version is too old and hasn't got the relevant C++17 fix yet
Comment 2 Kurt Hindenburg 2021-07-21 18:46:08 UTC 
Is gperf from outside KF5?  I don't have it installed anywhere that I can find.
Comment 3 Nicolas Fella 2021-07-21 18:47:59 UTC 
yes, gperf is an external thing

I did find https://ports.macports.org/port/gperf/
Comment 4 Kurt Hindenburg 2021-07-21 18:52:43 UTC 
Yes, but I don't have it installed.
Comment 5 Dawid Wróbel 2021-09-24 08:48:42 UTC 
I can confirm that this is an issue with gperf 3.0.3 shipped by default with macOS, up to the current Big Sur 1.6 (20G165). That version was released in 2007 (!):  http://ftp.gnu.org/pub/gnu/gperf

Please install gperf 3.1 (from 2017) with brew or macPorts.
