You need to make sure you have the headers for the kernel you're currently running. Make sure 'pacman -Q linux' --add -lts or-ck if appropriate --and
'uname -r' show the same version. If you just upgraded reboot.

:: failed to build droidcam package(s)

Thanks a lot for that Jame San! I made you a co maintainer and you can update changes. I'll merge them first thing in the morning; unless you're a bit faster than me haha

The current source tarball is rather old, I gather, and the latest package builds without encountering that same warnings treated as errors. Running a diff between the current (v4.1) and latest (v6.0) tarballs reveals a significant number of code changes in implementing the v4l2loopback_dc kernel module, which appears to be a custom and simplified modification of the official mainline v4l2loopback kernel module.

Please find changes returning this package to working order here: https://github.com/jamesan-unofficial-aur-pkgs/droidcam/commit/5f2a2c27a871c86d23158369febf22e6ee2a7110.

I also cleaned up the package in general and managed to:
- eliminate patching of upstream code as target lines are no longer present;
- remove conflict or dependency on v4l2loopback kernel module (i.e. it's unaffected by the presence of v4l2loopback-dkms);
- added support for i686 architecture as its supported by a parallel package upstream;
- eliminated all dependencies as the binary executables are statically linked (I suspect the gtk2 dependency is uneeded);
- rearranged lines and separated the logic into the prepare(), build(), and package() functions.

The entire set of changes can be found in a series of commits here: https://github.com/jamesan-unofficial-aur-pkgs/droidcam/commits/master with the repo located here: https://github.com/jamesan-unofficial-aur-pkgs/droidcam.

There's no mechanism for pull/merge requests in the AUR, but I can push my commits into the repo if you add me as co-maintainer (or you can fork that repo of mine and DIY).

Sorry about not replying, I don't use this often but I do want to make sure it's at working haha. Let me know how it goes @jamesan.
If anyone wants to test the prebuilt package I'll make it available on my website. I'll see if I can put a repo too.

I'm struggling with the identical error (exact log output as posted) posted by nipsky, which presents when compiling the v4l2loopback_dc kernel module as the last step in the package() function. I'm also using the CK patchset variant of the same kernel version as nipsky: 4.6.3-1-ck

There's reference to droidcam's upstream build process fails at this kernel module for versions of the Linux kernel above 3.18/3.19. Let me see if this error vanishes if I boot up with a 3.xx kernel.

I get an error trying to build the package:

I get a "file or folder not found" window. clicking on ok will freeze the software. using 5.1 but writing here because discussion is here.

@AwesomeHaircut no package should ever modify anything in /home. Example configuration files belong in /usr/share. You should then add a message in a post_install() script about where to find an example config file.

@erikvanvelzen thanks
it should be updated now.

I didn't add the settings because aur packages shouldn't modify the ~ folder. I might be wrong though.
