Iriunwebcam - missing v4l2loopback kernel module

this is kind of related to:
Continuing the discussion from Problem with dkms with v4l2loopback-dkms RT kernel manjaro:

I want to use an iphone as webcam with my Manjaro maschine usind Iriunwebcam.
The Iriunwebcam program on my Computer provides this alert

initialization failed
You may want to run 
sudo rmmod v4l2loopback; sudo modprobe v4l2loopback

which says:

rmmod: ERROR: Module v4l2loopback is not currently loaded
modprobe: FATAL: Module v4l2loopback not found in directory /lib/modules/5.15.60-1-MANJARO

I can identify a package named v4l2loopback-dkms being installed. Apparently modprobe can not find it. Probably it’s me being inexperienced with kernel modules & how to install/load them.

can somebody push me into the right direction? Do I simply need to cp any of this

$ locate v4l2loopback

… into the mentioned /lib/modules/5.15.60-1-MANJARO folder?
or build it (if so, would that be a make operation inside /usr/src/v4l2loopback-0.12.5/)?

thx, I am trying to work through those atm

seems the remote has slightly changed:

git clone works better

hm …

  1. $ updpkgsums downloads a .deb package
  2. there seems to be missing the command for building the package (is it just makepkg inside the repository & ignoring the iriunwebcam-2.7.deb package?)

No it has not - what you refer to is the information page

The cloneurl is still the same - you can use these urls where albeit more correct the .git is optional

You didn’t read the topic then

At the time this guide was writting - the updpkgsums command was necessary as the PKGBUILD was not well maintained.

The command is there - you just didn’t see it. And in the final parts of the guide you install using pacman -U command (replace $VERSION with the actual version from the filename)

sudo pacman -U iriunwebcam-bin-$VERSION.pkg.tar.zst
