Cannot mix incompatible Qt library (version 0x50904) with this library (version 0x50a01),Abort (core dumped)

[thor]

Had a similar problem trying to produce a port of some proggie (nomina 
sunt odiosa) which depends on QT5. Port mechanism built QT5 of different 
version from package.


Solution:

Fully remove the QT5. Ensure that corresponding install directories are 
empty or non-existent.

Then reinstall QT5 from packages, then reinstall your proggies from 
packages.

Then make "some proggie" observing that nothing including QT5 is built 
as a prerequisite. If something is required then stop the build and 
install the dependency from package.


In the future it's worthy to raise the problem to QT5 packagers' level.
