[Interest] Crash due to missing symbol

[Ben Haller]

Hi Alex.  Do you have the “deployment target” set to 10.10, not 10.14, in your project?  In Xcode this is in the project settings; in Qt Creator it’s a setting in the .pro file.  You can’t set it to be any earlier than the Qt version you are running against, however, or precisely this sort of thing will happen.  If you need to run on older OS X versions, you need to make sure the Qt version you’re using is compatible with those older versions.  (I forget where this information is, but Google always finds it for me.  :->)

Cheers,
-B.
