Arch Linux User Repository

@nobane In fact, the project seems to be quite old and no longer maintained (it has been down for 2 years). I have sent source correction request to H-M-H on GitHub.

@Zorn if you clone the aur repo you can set the rust version with rustup before you build the package. I was able to get it to build with 1.52.0 (first version I decided to try, it may work on a more recent version):

git clone https://aur.archlinux.org/weylus
cd weylus
rustup override set 1.52.0
makepkg -si

The compilation of Weylus fails due to the following error:

Compiling adler32 v1.2.0 error[E0310]: the parameter type T may not live long enough --> /home/zorn/.cargo/registry/src/index.crates.io-6f17d22bba15001f/rustc-serialize-0.3.24/src/serialize.rs:1155:5 | 1155 | fn decode<D: Decoder>(d: &mut D) -> Result<Cow<'static, T>, D::Error... | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ | | | the parameter type T must be valid for the static lifetime... | ...so that the type T will meet its required lifetime bounds... | note: ...that is required by this bound --> /usr/src/debug/rust/rustc-1.76.0-src/library/alloc/src/borrow.rs:180:30 help: consider adding an explicit lifetime bound | 1151 | impl<'a, T: ?Sized + 'static> Decodable for Cow<'a, T> | +++++++++

Great, now it works!

Ok, please try again. I think the problem was the linking order of some libraries which I have changed now.

When I change my rust toolchain from nightly to stable, this error disappear. I guess it will be an interesting bug :P. Thank you!

That's weird, I can not reproduce this error on my system and also not within a docker container running archlinux:latest, in both cases Weylus builds just fine.

Hey, this package now fails to build. I did nothing but running yay -S weylus, and following got output:

...

@HMH_13 thanks for replying! Facepalm, I missed the features flag.

@tinywrkb that's what happens by default, but Weylus can be built using the system ffmpeg and libva libraries by passing --features="ffmpeg-system" to cargo. This avoids downloading ffmpeg during the build as this is rather bad practice for packaging things. The reason why ffmpeg is downloaded, built and statically linked by default is to make sure Weylus runs with hardware acceleration even on older systems. However, this is not a problem on Arch Linux and that's why I am using the system ffmpeg library here.

Also thanks for packaging Weylus for Flatpak!
