Builds in a clean chroot after making the following changes:

Edit:
If you still can not build the package with the above changes applied,  post the full output of makepkg.  Also are you a custom version of ffmpeg or any of its dependencies?

Re: [SOLVED] qtcam-git fails to build

First of all, thank you.
Second, I must be missing something

$ ./Qtcam
file:///usr/share/qml/qtcam/Views/qtcam.qml: No such file or directory
QObject::connect: Cannot connect (nullptr)::stopCamPreview() to (nullptr)::triggerModeCapture()

Use make install which previously commented,  but had to patch the target path to /usr/share from /usr.

Re: [SOLVED] qtcam-git fails to build

Thank you!

I've tried using command "cp" a it seems that "install" doesn't have recursive action, and it didn't work.
Where can I find more on function "prepare()"?

Re: [SOLVED] qtcam-git fails to build

Have you added the .desktop file icons to the PKGBUILD?  You could notify the maintainer the PKGBUILD fails to build,  flag it out of date and link to this thread or provide an update PKGBUILD.
Edit:
Package has no current maintainer,  you could adopt if you wanted to maintain it.

I'd love to. To whom do I send an application?

Re: [SOLVED] qtcam-git fails to build

No need to send an application.

register an aur account .
login to aur, navigate to the qtcam-git page and you'll notice an "adopt package" option .

For submitting you'll need a personal ssh key pair.
Check https://wiki.archlinux.org/index.php/AU … guidelines thoroughly .
