Thanks for the reports! Building should work again. But as already pointed out, the latest release is a little dated. If you want to try the latest master you can try weylus-git (not provided by myself but @PeterWang-dev).

build() fails for me with error[E0310]: the parameter typeTmay not live long enough:

error: could not compile `rustc-serialize` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...

rustc --explain E0310: 

A parameter type is missing a lifetime constraint or has a lifetime that does not live long enough.

Erroneous code example:

// This won't compile because T is not constrained to the static lifetime
// the reference needs
struct Foo<T> {
    foo: &'static T
}

Type parameters in type definitions have lifetimes associated with them that represent how long the data stored within them is guaranteed
to live. This lifetime must be as long as the data needs to be alive, and missing the constraint that denotes this will cause this error.

This will compile, because it has the constraint on the type parameter:

struct Foo<T: 'static> {
    foo: &'static T
}

Please move the rust download stuff out of build() into prepare() so that build() can run in an offline environment.

And also, please set $CARGO_HOME or such to a sub directory of $srcdir so that rust does not clutter the build user's home directory but everything that this PKGBUILD does is restrained to $srcdir and $pkgdir as it should be.

Regards and thanks for maintaining!

@nobane In fact, the project seems to be quite old and no longer maintained (it has been down for 2 years).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:

Great, now it works!

HMH_13 commented on 2022-05-20 15:30 (UTC)

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

hammer commented on 2022-05-17 02:48 (UTC)

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