I have the latest available version installed:

$ yay -Qi libjpeg-turbo | grep Version
Version         : 2.0.5-2

@klingt.net maybe you have outdated version of "libjpeg-turbo"? It seems compiler picks the version, which do not have "tjGetErrorStr2" defined, which has been added in 1.5.3+: https://github.com/libjpeg-turbo/libjpeg-turbo/releases/tag/1.5.90.

error making: droidcam (v4l2loopback-dc-dkms)

@pickfire thanks for noticing, you are right. I added "libappindicator-gtk3" as optional dependency now, as we do the same with "gtk3", given that "droidcam-cli" works without both of those packages.

I wonder, perhaps this optional dependencies should be dropped and just added as regular dependencies.

libappindicator-gtk3 is a dependency, not just make dependency. Otherwise, droidcam

droidcam: error while loading shared libraries: libappindicator3.so.1: cannot open shared object file: No such file or directory

jonseitz I suspect that happens, because you have "." in your PATH, so local "install" script takes precedence over "global" "install" binary. I'll fix that, it seems like a reasonable case.

Ran into an issue installing just now, getting the following error:

==> Starting package_droidcam()...
~/builds/droidcam/src/droidcam-1.3/linux ~/builds/droidcam/src
Invalid parameters: '-Dm755' and 'droidcam'
==> ERROR: A failure occurred in package_droidcam().
    Aborting...

It seems that the issue is that the calls to install ... in the package scripts were referencing the install script in src/droidcam-1.4/linux/, instead of /sbin/install. I was able to get it working by changing the PKGBUILD to:

Possibly it's something specific to my system, but dropping this here in case anyone runs into the same.

first, I wanted to thank the maintainers. Secondly, there is an easy fix for manjaro users. You just need to install kernel headers specific to your kernel version. So after installing linuxXX-headers, reboot and then install droidcam.I've tested it and it works perfectly fine. Best of luck!

@LenLord That's the problem, I've already did this before to try the installation of DroidCam: [albert@ThinkPad ~]$ sudo ln -s /usr/lib/libusbmuxd.so /usr/lib/libusbmuxd-2.0

And the build still the crashes...

UPDATE: I've found the issue, it missed the .so in libusbmuxd-2.0

Regards and thank you very much!!
