feat: support the aarch64-unknown-linux-gnu host toolchain - #85
Merged
Conversation
wasix-org/rust has published rust-toolchain-aarch64-unknown-linux-gnu
since v2026-08-05.1+rust-1.97, but `guess_host_target` never listed the
triple, so aarch64 Linux hosts bailed out with "The WASIX toolchain is
not available for download on this platform." before looking at the
release assets at all.
Add the arm; the existing asset-name pattern
(rust-toolchain-{target}.tar.gz) already matches what the release ships.

wasix-org/rusthas shippedrust-toolchain-aarch64-unknown-linux-gnu.tar.gzsincev2026-08-05.1+rust-1.97, but the host table inguess_host_targetonly ever listed four triples:On an aarch64 Linux host it therefore returns
None, andinstall_prebuilt_toolchainfails with:before it ever looks at the release assets. The asset it needs is right there in the release.
This surfaced in wasmerio/wasmer#6698, where the
linux-arm64CI job runs the WASIX Rust test fixtures: https://github.com/wasmerio/wasmer/actions/runs/31015208374Notes
No other change is needed — the existing asset lookup builds the name from the triple (
rust-toolchain-{target}.tar.gz), which already matches what the release publishes.I did not bump the version, since that looks like a separate step in this repo. A crates.io release is required before the
wasix-org/cargo-wasixGitHub action picks this up, as the action installs by the version inCargo.toml.🤖 Generated with Claude Code
