Incompatible library version: qwt requires version 5.13.0 or later, but QtPrintSupport provides version 5.12.0

I found my problem similar to this: (https://forum.qt.io/topic/94142/incompatible-library-version-qwt-requires-version-5-10-0-or-later/4).

However, the original problem is solved by re-compiling the qt project, while this is not cannot solve my problem here.

I am running qt creator on mac OS Catalina 10.15.1, the error message on the qt is:

dyld: Library not loaded: /usr/local/opt/qt/lib/QtPrintSupport.framework/Versions/5/QtPrintSupport
  Referenced from: /usr/local/Cellar/qwt/6.1.4/lib/qwt.framework/Versions/6/qwt
  Reason: Incompatible library version: qwt requires version 5.13.0 or later, but QtPrintSupport provides version 5.12.0
00:46:15: The program has unexpectedly finished.

Thanks.

Hi and welcome to devnet,

Did you also install Qt through brew ? If not then do it and use that version to build your project.

I reinstalled the qt with version 5.14.0 in the latest release tab. The problem is solved. Thanks for your time.

For the record: Qwt 6.1 supports all ( ! ) Qt versions >= 4.4 - including all versions from the Qt5 cycle.
Whatever the problem here was - it should not have been because of Qwt.
