What happened?

The build results in:

vbox_fb.c:214:10: error: ‘struct fb_ops’ has no member named ‘fb_debug_enter’
  214 |         .fb_debug_enter = drm_fb_helper_debug_enter,
      |          ^~~~~~~~~~~~~~
vbox_fb.c:214:27: error: ‘drm_fb_helper_debug_enter’ undeclared here (not in a function); did you mean ‘drm_fb_helper_damage_area’?

      |                           drm_fb_helper_damage_area

The code:

virtualbox/src/VBox/Additions/linux/drm/vbox_fb.c

Lines 219 to 220 in 581733f

	.fb_debug_enter = drm_fb_helper_debug_enter,
	.fb_debug_leave = drm_fb_helper_debug_leave,

The hooks were removed by torvalds/linux@7068d42:

    fbcon: Remove fb_debug_enter/_leave from struct fb_ops

Vbox needs to adapt, likely remove the hooks.

How can we reproduce this?

Just build against the newest kernel.

Did you upload all of your necessary log files, screenshots, etc.?

• Yes, I've uploaded all pertinent files to this issue.

@jirislaby ,

Errors you are observing are related to the Guest Additions, not to the host package. Errors come from vboxvideo kernel driver. This driver will be deprecated for kernels 7.0 (and newer) starting from the next release. This mean that official Guest Additions will still ship driver source code, however its build will be skipped for 7.0+ kernels (older kernels are still supported though). Starting from the next release, users are encouraged to use vboxvideo which comes with Linux kernel itself if guest is using VBoxVGA/VBoxSVGA graphics (note, for modern Linux guests it is recommended to use VMSVGA graphics instead). Corresponding fixes are already available on our test builds page (https://www.virtualbox.org/wiki/Testbuilds) for the "Latest 7.2.x test builds" and "Development snapshots".
