Cannot run on Fedora 30 Wayland

[pop]

Hey team! I am super interested in trying space-menace but I can't get the dang thing to run! It compiles just fine for me, but won't run. 😞 Let me know if I'm doing something wrong or if I found a real bug we can fix.

The error

It looks like you are running it in debug mode. Try compiling and running it with optimizations enabled:
cargo run --release

Likely resolved by amethyst/rendy#182

[pop]

@azriel91 Any way I can verify that before closing the issue? I'm not sure how to trick Cargo into using the master version of rendy. 🤔 😕

[azriel91]

yeap, add this to Cargo.toml:

[patch.crates-io]
rendy = { git = "https://github.com/amethyst/rendy.git" }

[pop]

Hmm. Cargo ignores that patch when I add it to Cargo.toml. I haven't dug into how to properly patch dependencies. I might dig deeper and let you know what I find.

I've recreated the problem on Debian Buster with Wayland.
When adding this to Cargo.toml:

[patch.crates-io]
rendy = { git = "https://github.com/amethyst/rendy.git" }

I get the following message:

warning: Patch `rendy v0.4.0 (https://github.com/amethyst/rendy.git#a8ac0de9)` was not used in the crate graph.
Check that the patched package version and available features are compatible
with the dependency requirements. If the patch has a different version from
what is locked in the Cargo.lock file, run `cargo update` to use the new
version. This may also occur with an optional dependency that is not enabled.

I believe Amethyst must be updated to use a newer version of rendy before this will work. If you just want to see it working locally, you could try to apply commit amethyst/rendy@08df51d to amethyst/rendy@b3904b6 and patch that into Cargo.toml (untested).

If it will be a while before Amethyst can use rendy v0.4.0, perhaps a backported fix can be released as v0.3.3?

[pop]

Any word on this? Think we could get a backport or could we merge Amethyst libraries to using rendy >= 0.4.0? I can't run any of the Amethyst showcase projects or the 2D project template.

[krankur]

@pop I don't have much knowledge on this. @azriel91 or some other member from the core Amethyst team may have some information.

[azriel91]

The master branch of amethyst has got rendy 0.4.1 (amethyst_rendy/Cargo.toml), so the patch should hopefully work if you cargo update as well (seeing that space-menace master depends on amethyst master).

Repasting here for convenience:

[patch.crates-io]
rendy = { git = "https://github.com/amethyst/rendy.git" }

[valkum]

The fix seems to not be included in 0.4.1
See https://github.com/amethyst/rendy/blob/v0.4.1/graph/src/node/render/pass.rs#L443

amethyst/rendy@561847a seems to fix the problem. Maybe we can release rendy v0.4.2

[mxgrey]

To test a hypothetical 0.4.2 release of rendy, you can use the following patches to the current master branch of amethyst:

This uses a fork I've made of rendy where only the pertinent fix was added to v0.4.1.

Exporting the environment variable WINIT_UNIX_BACKEND=x11 seems to also be a valid workaround until a fix makes it into an Amethyst release.
