Virtualbox-host-dkms failed to compile with Makefile Error 2

Support Kernel
1

Hello, I am having issues compiling the Virtualbox DKMS host modules for the linux kernel on Manjaro. I’ve tried everything I could have thought of to try. I’ve compiled a custom kernel, and pretty much all I can think of. And yes, I’ve installed headers and all. I’ve had this issue since 5.9.16 or so. Here’s the make log for DKMS.

DKMS make.log for vboxhost-6.1.16_OSE for kernel 5.11.0-rc2-CUSTOMMANJARO (x86_64)

I hope someone can help me with this. I’d appreciate anything I can get. Thank you!

@TotalBasshead Where did you get the source?

By the way… there are dkms available on Manjaro and AUR:

Repo:

pamac install virtualbox-host-dkms virtualbox-guest-dkms

AUR:

pamac build virtualbox-host-dkms-svn virtualbox-guest-dkms-svn
3

Hello! I have used pacman to install the modules, and I tried the official Virtualbox.run stuff and still no luck. I’ll try the pamac stuff.

4

I keep getting this each time:

==> dkms install --no-depmod -m vboxhost -v 6.1.16_OSE -k 5.11.0-rc2-CUSTOMMANJARO
Error! Bad return status for module build on kernel: 5.11.0-rc2-CUSTOMMANJARO (x86_64)
Consult /var/lib/dkms/vboxhost/6.1.16_OSE/build/make.log for more information.

5

Ok, Im trying the AUR one now.

6

Wow, this is interesting. It installed for all of the kernels… expect for the one I compiled.

7

I have the same issue when I on 5.11.0-rc6. It looks like this is the same issue described in bugs(dot)gentoo(dot)org(slash)762994, and the issue was fixed after adding the “#include <linux/ethtool.h>”.

(sorry, seems like the board isn’t letting me post links, hence the deconstructed url above)

8

@edtan How do you add that? Sorry I’m not all that versed in linux.

9

I think these changes need to be added to the virtualbox-host-dkms package, but I’m not sure how to go about contributing this change.

Anyways, here’s what I did manually for now. Note that it’ll likely get wiped out the next time you update the package or reinstall it. You should only do this if you compiled your own kernel using the “traditional compilation” method (sorry, it’s still not letting me post links - search google for “arch traditional compilation”). If you did not compile your own kernel, then you might have a slightly different issue.

Open the following file:

/usr/src/vboxhost-6.1.16_OSE/vboxnetflt/linux/VBoxNetFlt-linux.c

and insert the following line right after “#include <linux/netdevice.h>” (around line 40):

#include <linux/ethtool.h>

Then run the following (you will need to replace the last argument with the name of your kernel that you manually compiled (likely can be found under /lib/modules):

sudo dkms install --no-depmod -m vboxhost -v 6.1.16_OSE -k 5.11.0-rc6-MANJARO+
depmod

@edtan
Thank you, I’ll give that a shot tomorrow.
