Ubuntu v4l2loopback dkms will not build on kernel 6.8 #72

Closed aplund closed 4 months ago

aplund commented 5 months ago

I tried building with the 6.8-rc2 kernel, and the v4l2loopback ubuntu branch forks from a point where strlcpy is still used. This commit is in the 6.8 kernel, and hence the module will not compile from this branch. The vanilla v4l2loopback does compile.

    string: Remove strlcpy()

    With all the users of strlcpy() removed[1] from the kernel, remove the
    API, self-tests, and other references. Leave mentions in Documentation
    (about its deprecation), and in checkpatch.pl (to help migrate host-only
    tools/ usage). Long live strscpy().

Hi @aplund,

sorry, but I think you won't have chance with this kernel. Can't speak for Ubuntu though, as I'm using Arch (btw.). As of now, kernel version 6.7.x is not supported (even on Arch). I suspect it'll be the same for 6.8.x.

Added a note to the readme, that recommends using an LTS kernel. But again, no clue, if that will work on Ubuntu though.

I'll close this one, as this won't be fixed in this repo (except someone will provide a PR).

Best regards and good luck Stefan
