QGroundcontrol building error (daily) on MacOS High Sierra

#1

Hello

I upgraded to Qt 5.11 as this is documented as the only Qt version to be supported. Before upgrading the build completed without errors. Now I get an error about a future that is unavailable, see compiler output below. I am a bit lost here and have no idea why this error pops up now. Any help would be much appreciated.

Thank you
Dirk
