I've had this kind of error:
Code: Select all
$ VirtualBox
VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/usr/lib/virtualbox/VirtualBox.so",) failed: /usr/lib/libQtNetwork.so.4: undefined symbol: _ZN14QObjectPrivate15checkWindowRoleEvThe solution was to add /usr/lib in /etc/ld.so.conf so simple, so logical, but so long to find that it was that!
hope it may help anyone else
have a good day
