Arch Linux User Repository

Upstream is not maintaining the project and it currently won't build. @oberon2007 and I have disowned the package.

As an alternative, I suggest Gear Lever (Flatpak, WIP AUR package).

I couldn't file an upstream pull request. I don't know if it even needs fixing upstream. Because upstream's "appimagelauncher" repo isn't even using their own latest commit on the "zsync2" repo. They're using something from 2019, latest commit was from December of 2023.

Thanks for the hint regarding Gear Lever, though.

@kode54: I see no upstream pull request. Either way, apparently upstream doesn't care about releasing a new version. I may disown this package as it no longer maintainable. Check out Gear Lever instead. I don't even use AppImages anymore.

Here's a patch to get zsync2 building with GCC14 and get this whole thing built:

https://gist.github.com/kode54/1044dc5cd31c614ed1e92b4155a0d0c5

Edit: And they're not even using the latest upstream zsync2 commit in AppImageLauncher, they're using a commit from 2019.

The issue is that zync2 no longer build with gcc14

@w9hdg: No one can read that. Please use a pastebin service for longer output and proper formatting for short bits:

@25pwn Added this in zsync.c before the function call and it worked char strptime(const char buf, const char format, struct tm tm);

When building with CC=clang CXX=clang++, I get:

This does not happen with GCC.

Thanks yochananmarqos for him appimagelauncher 2.2.0-6 stable package!!!
