Steps to reproduce (if you know):

Install Arch Linux
sudo pacman -Syyu base-devel git
git clone https://aur.archlinux.org/popsicle.git
cd popsicle
makepkg -s

popsicle-git on AUR still have old build instructions at the moment, realized now when checking, I have updated it locally for now

Expected behavior:

pkgbuilds build fine

Other Notes:

[tormeh]

Similar problem for Nix: NixOS/nixpkgs#269914

[mmstick]

I'll check it out. Probably just needs a dependency update

[tormeh]

Indeed, a similar problem seems to have been fixed for Zenith with a dep update: bvaisvil/zenith#135

[yochananmarqos]

Still doesn't build:

[FabioLolix]

Confirm is not resolved yet

[mmstick]

Depends on mdaffin/loopdev#62 being resolved

[mmstick]

Try building from the branch at #210

[yochananmarqos]

Yes, it builds now.

[FabioLolix]

It build and work
