/var/log/vboxadd-setup.log

I'm running VirtualBox "VirtualBox Graphical User Interface Version 6.1.38_SUSE
r153438" on Leap 15.4 / kernel 5.14.21-150400.24.21-default on my host system
and the same in my guest system.

When i mount the VBox_GAs_6.1.38 virtual cd on my guest and run the
VBoxLinuxAdditions.run script i get:


SuSE:/run/media/gerben/VBox_GAs_6.1.38 # ./VBoxLinuxAdditions.run

From the /var/log/vboxadd-setup.log file it looks like building the graphics
driver fails. (i have attached the vboxadd-setup.log file)
Also look at the end of the file where is complains about incompatible types.
