[arch-general] Linux 5.3 - Virtualbox 5.2.32 modules fail to build - upstream bug opened

[Ralf Mardorf]

virtualbox-bin from AUR is already patched with a fix.
https://aur.archlinux.org/cgit/aur.git/commit/?h=virtualbox-bin&id=83f1870f15d86179a665dc0c6b36815a385f6fbe

You could try to adapt it to your virtualbox-bin-5 tarball from AUR without much editing...

$ wget -q https://aur.archlinux.org/cgit/aur.git/snapshot/virtualbox-bin{,-5}.tar.gz
$ tar xf virtualbox-bin.tar.gz; tar xf virtualbox-bin-5.tar.gz
$ diff -r virtualbox-bin virtualbox-bin-5

...perhaps you have good luck. Sometimes patches apply with an offset and work out of the box.
