I come across a problem that prevents Virtualbox SVN from running in
Arch Linux with Qt 5.11.1. Compilation and installation are successful,
but virtualbox will not start as Qt will complain
Qt FATAL: FATAL: The application binary appears to be running setuid,
this is a security hole.
The premission of the virtualbox is set to be 4755.
The PKGBUILD and the patches files are here:
It is the same as the official package of virtualbox in archlinux, but I
found no problem in the official package.
