virtualbox does not start and crashes with undefined symbol error: _ZN11QToolButton13checkStateSetEv

[wbwb]

I updated my system yesterday. Following that, virtualbox does not start anymore. On the CLI, and before virtualbox crashes, I only get these messages:

Code: Select all

~>VirtualBox 
Warning: program compiled against libxml 210 using older 209
Warning: program compiled against libxml 210 using older 209
/usr/lib/virtualbox/VirtualBox6: symbol lookup error: /usr/lib/virtualbox/UICommon.so: undefined symbol: _ZN11QToolButton13checkStateSetEv, version Qt_5

I found claims on the net, that `_ZN11QToolButton13checkStateSetEv` is a symbol from the `libQt5Widgets` library. But on my system (7.0.10-lp155.5.11, openSUSE Leap 15.4, backport kernel 6.5.7-lp155.2.ge060757-default, Qt version 5.15.2) a symbol dump does not show such symbol for `libQt5Widgets.so`.

Now I'm stuck.
Any suggestion how to fix this and get virtualbox running again would be most appreciated.

Additional info: My full stack of VirtualBox software is

Code: Select all

~>rpm -qa | grep virtualbox
virtualbox-7.0.10-lp155.5.11.x86_64
virtualbox-qt-7.0.10-lp155.5.11.x86_64
virtualbox-host-source-7.0.10-lp155.5.11.noarch
virtualbox-kmp-default-7.0.10_k6.5.7_lp155.2.ge060757-lp155.5.7.x86_64

Needless to say, that indeed, `virtualbox-7.0.10-lp155.5.11` logs show that it has been compiled on Fr 13 Okt 2023
If necessary, I can certainly also list this for the Qt5 libs.

I think the problem is here:

I updated my system yesterday.

The easiest way to getting things working again is to roll back the update using your host disk image backups.

Also, Linux kernel updates to the latest and greatest (which I cannot tell if you did, so this is merely for information) require Virtualbox updates to a version that is released after the new kernel date. Virtualbox won't run on a kernel newer than Virtualbox.

You can try the test builds and development snapshots, or restore a previous host backup.

FWIW, all of your packages (including the VirtualBox packages) were built by openSUSE, so you should better ask them why their packages don't fit together.

FWIW 2, without C++ name mangling the symbol name would read QToolButton::checkStateSet.
