Slackware 14.2 kernel 4.4.172 cannot compile guest additions (#18315)

[ModEdit; related ticket: #18315: Kernel modules do not build with linux kernel 4.4.169, which appears to be fixed with builds r128999 and later, for both 5.2.27 and 6.0.5.]

After updating Slackware 14.2 to kernel 4.4.172, guest additions wil not compile.

I am prompted to look at /var/log/vboxadd-setup.log to find out what went wrong.

I don't fully understand the solution suggested in vboxadd-setup.log, i.e. how do I run 'make oldconfig && make prepare' on kernel source to fix it.

I've been at this issue on and off over the past week. I've found a solution that I can understand and implement here

https://slackblogs.blogspot.com/2019/02 ... ation.html

On that blog there is also a link to LinuxQuestions.org, where the topic is also discussed.

Any suggestions, advice would be greatly appreciated. I'll wait a bit before I implement any solution.

P.S. Issue occured with VBox versions 5.2.24, 5.2.26 and 6.0.4, didn't test any other versions.

I have logs from all versions, am only including the latest:

You don't have to rerun any make jobs, there's a source incompatibility with the new kernel, see https://www.linuxquestions.org/question ... ost5956080

You can unpack the guest additions tarball and patch it yourself (or wait for updated GA's in the Test Builds area)

Hi, I'm having the same problem and with the help of this posting I've been able to solve it.
Thanks!

There's an open ticket about this, #18315: Kernel modules do not build with linux kernel 4.4.169, and another thread, which I should have merged them at their birth, now it's too late: vboxdrv build failure, VBox 5.2.26 32-bit, kernel 4.4.168 (#18315)

Can you people try the latest test builds from https://www.virtualbox.org/wiki/Testbuilds and see if it fixes the issue without the workaround? According to "michael" in the other thread:

Please try the current test builds[1] and report back on ticket 18315[2] if possible.

Confirmed, works for me now without intervention.

Thanks @bbender-v for the feedbak! A developer just "got their wings"...

I'll wait for confirmation from 'Etepetete' for a couple of days, before marking the thread as [Fixed], but I will edit the 1st message to include a note about the recent developments...

vboxfs does not compile on latest slackware with latest test build. However, vboxvideo compiles and works perfectly.

vboxfs does not compile on latest slackware with latest test build

Why is that? Where's the output of the GAs installation/compilation?

This is getting multiple (4) thread coverage, and I missed that fact, I should have merged them. So, I'm locking this one, please continue the discussion in: [Fixed] vboxdrv build failure, VBox 5.2.26 32-bit, kernel 4.4.168 (#18315).
