kmeakin (Aug 05 2024 at 20:26): kmeakin (Aug 05 2024 at 20:26):I'm trying to run ./ci/run-tests.sh so I can reproduce the CI failures on https://github.com/bytecodealliance/wasmtime/pull/9074 locally. But I'm getting:
error: failed to run custom build command for `test-programs-artifacts v0.0.0 (/home/karl/git/third-party/wasmtime/crates/test-programs/artifacts)`

Pat Hickey (Aug 05 2024 at 21:13):rustc --version?
Pat Hickey (Aug 05 2024 at 21:21):i checked out your branch locally and cant reproduce with rust 1.80 on mac aarch64 (host architecture almost certainly shouldnt matter for this part of the build, since its a cross build)
Pat Hickey (Aug 05 2024 at 21:21):my best guess is to cargo clean and try again
kmeakin (Aug 05 2024 at 22:03):rustc --version --verbose
rustc 1.82.0-nightly (176e54520 2024-08-04)
binary: rustc
commit-hash: 176e5452095444815207be02c16de0b1487a1b53
commit-date: 2024-08-04
host: x86_64-unknown-linux-gnu
release: 1.82.0-nightly
LLVM version: 19.1.0
switching to stable toolchain seems to have fixed it
Pat Hickey (Aug 05 2024 at 23:15):ah, yeah, i have no idea what might break that with nightly, hopefully its just some temporary blip
Pat Hickey (Aug 05 2024 at 23:17):unfortunately, the adapter is some of the gnarliest code we have, it uses various shenanigains and sleights of hand so that rustc/llvm produces a wasm binary that doesnt have any const data, and it wouldnt shock me if llvm got smart enough to see through some of those tricks...
Alex Crichton (Aug 06 2024 at 07:24):I think I've figured out what's going on here and I'm endeavouring to debug
Alex Crichton (Aug 06 2024 at 13:05):looks like this is a regression from https://github.com/llvm/llvm-project/commit/ba3c1f9ce30cf4f8aee5f1961df74d65e11d53bc which first got into rust with llvm 19 which happened relatively recently in nightly
kmeakin (Aug 07 2024 at 22:47):Would it help to add a rust-toolchain.toml file so contributors aren't broken by having the wrong version?
Alex Crichton (Aug 09 2024 at 18:03):I've opened https://github.com/bytecodealliance/wit-bindgen/pull/1021 to solve this, personally I'd prefer to not do rust-toolchain.toml, I'll leave a comment on the PR
Alex Crichton (Aug 12 2024 at 21:29):To close the loop here I believe that main as-of now should be able to build on the latest nightly
