On: "Cannot mix incompatible Qt library (5.15.3) with..."

[Budi]

Tried to build an Open Source on a public repo:

https://sourceforge.net/projects/qtrans0/files/

but upon finished build, it got interrupted when launched:

"Cannot mix incompatible Qt library (5.15.3) with this library (5.15.4)"

How did anyone has experienced such kind issue solve it ?
Please help sincerely.

@Budi
one of this below must be updated to in accordance with qt base

$ pacman -S qt5-imageformats qt5-multimedia  qt5-speech qt5-svg qt5-tools qt5-wayland qt5-x11extras

not know which one precisely

@Budi
Since (I don't think) that download contains any Qt library files --- it's just an application which uses what you already have installed Qt-wise --- your problem should be in the Qt5 installation you already have. How did you get all the Qt source or library files you use?

@JonB
It started trouble when the Qt5 is updated in a rolling update type OS to be so cutting/bleeding edge.

This case on Arch, seems bit often happen to be problematic as library often few ways ahead than that of some common apps

So How the definitive steps to solve it ?

@Budi
You might start by running ldd on all the Qt shared library (.so) files you are using, to see if you can spot some version mismatch (15.2 vs 15.4), and whatever equivalent on the lib....*.a files you are trying to link against. Make sure your Arch is fully up-to-date for all (Qt) packages. Make sure you do not somewhere deliberately have a 15.4 library directory as well as a 15.3 one.
