Arch Linux User Repository

When I tried to upgrade webcamoid today, my computer ran out of memory and it killed the build about half way through. did anyone else experience anything similar?

Update: I had MAKEFLAGS='-j'. When I removed that it complied fine (but very slowly). I've cautiously added that back.

Thanks, I just forgot to to update that dependency.

Is the dependency qt5-multimedia (optional) – Camera capture still up to date considering this package otherwise using Qt 6 now?

Oh, I did not know, I will wait until its available in the repositories and fix it.

The official vlc in "extra" repo is still of version 3.x (3.0.21-6) and webcamoid builds properly, Are you sure you have installed the version 4.0 of vlc? It is available only in AUR as vlc-git. And it is apparently not backward compatible which is illustrated by errors in my previous post. If so, you should exclude "vlc-git" from dependencies, or check if the version 3.x is installed, not 4.x.

I have updated my system, did checked and its building fine for me without any change. papavlos maybe your system was not fully updated when building the package?

Ok, I usually do not update my system before a release that's why I did not have the build error, will check.

I know the reason: I have installed in my system the vlc-git 4.0.0 (Qt6 based). instead of vlc 3.0.21 (Qt5 based). That's why all errors were due to incompatibility with vlc headers... After downgrading to vlc 3.x - webcamoid was built and installed without further issues. Case closed.

@hipersayan_x I have more carefully reviewed output of makepkg -sL command. I have found some errors. Only a few of them because of 5000 limitation:
