“unavailability of vmlinux” - missing dependency? #5

Closed mogoh closed 3 years ago

mogoh commented 3 years ago

Hello,

I tried to compile everything under a fresh fedora 34, and I got this output:

$ make

Am I missing some dependency?

I have a discussion thread at ask fedora if that is of interest.

mogoh commented 3 years ago

So I found it working anyway. But I still wonder what this means and if I should recompile it. If no one finds the time to comment, this issue could be closed.

It means that the utility depmod, which determines the interdependence among modules could not find that file. The message is a warning, which you can safely ignore.
