@mazieres I hadn't such problem, but I've pointed the source link to the main branch anyway.

@jcelerier v4l2loopback doesn't depends on such program, just install it manually.

This no longer builds for me, possibly because the main branch now seems to be called main instead of master. I can still install it if I run:

makepkg -so
git -C src/v4l2loopback checkout main
makepkg -ei

But it doesn't built automatically anymore.

Hello, I had to install the "pahole" package to be able to build this, else make.log had this error:

/bin/sh: ligne 1: pahole : command not found

@OllyHearn, you should try to install the linux-headers package; had the same problem and everything worked afterwards. Not sure why linux-headers is not listed as a runtime dependency.

Installed without issues, but when i try sudo modprobe v4l2loopback it returns Module v4l2loopback not found in directory /lib/modules/5.9.10-arch1-1 What I'm doing wrong?

Seems to be missing a requirement. pamac install v4l2loopback-dkms-git ends with:

Install DKMS modules [2/2]

Jus noticed that since v4l2loopback:0.11 I'm getting some warnings when upgrading package. Package works fine, but still it's kind a worrying. Is this the normal behavior?

No idea why, but this prompts me to install linux-headers even though I'm on linux-zen. I just removed that dep from the PKGBUILD, but I've never run into that before.

matmo commented on 2020-04-06 06:57

I am not quite sure what exactly is going on (let you know if I find time to debug), but I had to manually remove the dkms module (dkms remove) and could then build and dkms install from the source directory manually. Sounds like the paths in the .install file are maybe wrong...

This fails to install for me. pacman output:
