KeePassXC @2.7.5 Fails to start with Qt Library incompatibility error

[vallon (Justin)]

When I start KeePassXC in terminal, I see:

$ /Applications/MacPorts/KeePassXC.app/Contents/MacOS/KeePassXC
Cannot mix incompatible Qt library (5.15.9) with this library (5.15.10)
Abort trap: 6
[exit 134 | SIGABRT]

What is installed:

$ port installed '*qt*' and rdepof:KeePassXC
The following ports are currently installed:
  qt5-qtbase @5.15.10_0+openssl (active)
  qt5-qtmacextras @5.15.10_0 (active)
  qt5-qtsvg @5.15.10_0 (active)

Picking one lib out of the crashreport, I see /opt/local/libexec/*/QtSvc.framework/Versions/5/QtSvg, and:

$ ls -l /opt/local/libexec/qt5/lib/QtSvg.framework/Versions/5/QtSvg
-rwxr-xr-x 1 root admin 328648 Jun  7 10:23 /opt/local/libexec/qt5/lib/QtSvg.framework/Versions/5/QtSvg
$ ls -l /Applications/MacPorts/KeePassXC.app/Contents/MacOS/KeePassXC
-rwxr-xr-x 1 root admin 5740838 May 19 15:17 /Applications/MacPorts/KeePassXC.app/Contents/MacOS/KeePassXC

My build log indicates that on 6/7, qt5-qtsvg 5.15.9 was present, but on 6/8, qt5-qtsvg 5.15.10 was present.

It looks like KeePassXC was built against Qt 5.15.9, and after the upgrade to Qt 5.15.10, KeePassXC was not rebuilt, and it seems there is some compatibility issue.

Rebuilding KeePassXC right now to see if a rebuild fixes it.

(Or, maybe qt5-qtsvg didn't flag that its callers needed a rebuild; I don't know how this works)

Rebuilding did not help.

Uninstalled KeePassXC and qt5-* deps (qtbase, qtdeclarative, qtmacextras, qtsvg, qttools). There is nothing "qt5* and installed". Reinstalled KeePassXC, and the application launched.

Replying to vallon:

That's not how I interpret the error, which reads:

Cannot mix incompatible Qt library (5.15.9) with this library (5.15.10)

It is clearly talking about two librarires. It is not talking about the KeePassXC program.

It would be highly unusual for a program to need to be rebuilt just because Qt was updated to a new minor version.

Uninstalled KeePassXC and qt5-* deps (qtbase, qtdeclarative, qtmacextras, qtsvg, qttools). There is nothing "qt5* and installed". Reinstalled KeePassXC, and the application launched.

Since you got everything working by uninstalling and reinstalling, I don't know what else we could do here.
