how to resolve missing symbol: __chkstd_darwin in libSystem.B.dylib (OSX)

Question

I have a desktop application which I developed with the Qt framework. In terms of backward compatibility on OSX I have a problem: The app is compiled on 10.15 and works fine on 10.15 and 10.14. This binary also launches with 10.13 but at some point throws an errors about missing symbols (__chkstk_darwin ) in libSystem.B.dylib:

Can anyone explain me how to approach this issue ?

Thanks in advance, best

Answer 1

QMAKE_MACOSX_DEPLOYMENT_TARGET=10.13 has to be part of the PRO-File. This was already the case which is why I was confused. Eventually we could figure that there was an additional lib involved which was not compiled for 10.13 and resulted in the actual issue. After compilation for 10.13 and using this lib the problem was resolved.
