guest additions do not build with 4.7 kernel => Fixed in SVN

[Andre Robatino]

Error from Fedora Rawhide x86_64 guest with 4.7.0-0.rc0.git8.1.fc25.x86_64 kernel:

Error! Bad return status for module build on kernel: 4.7.0-0.rc0.git8.1.fc25.x86_64 (x86_64)
Consult /var/lib/dkms/vboxguest/5.0.20/build/make.log for more information.

I added the new make.log on the assumption that the output change was due to the new kernel. However, there was a new version of dkms to implement parallel build on multiprocessor systems (see ​https://bugzilla.redhat.com/show_bug.cgi?id=1334103 ) and that was probably responsible.

Same issue here. Tried to build modules on Ubuntu 16.04 against kernel 4.7.0rc1:

There also were warnings:

The correct fix is actually r61429. This fix will be part of the next maintenance releases.

[Frank Mehnert]

Grr, forget my last comment. Wrong defect. This defect is about the Guest Additions while I meant the vboxnetadp fix :-/

[Frank Mehnert]

Fix in r61431. The latest test builds have the fix, in particular the Guest Additions .iso image.

[Andre Robatino]

Confirmed that 4.7 guest additions build in VB 5.0.20 when using VBoxGuestAdditions_5.0.21-107750.iso. Thanks!

[Frank Mehnert]

Fixed in 5.0.22.
