Opened this issue · 8 comments
Expected Behaviour
Build cargo run --bin example-runner-wgpu or cargo run --bin example-runner-ash successfully on macos.
Example & Steps To Reproduce
- Clone the repo on macos.
- Install rust environment etc.
- Run build command
cargo run --bin example-runner-wgpu
System Info
- Rust: [nightly-2024-04]
- OS: [macOS 15.1.1]
- GPU: [Apple M1 Max]
- SPIR-V: [SPIRV-Tools v2024.4 v2024.4.rc1-0-g6dcc7e35, Target: SPIR-V 1.6]
Backtrace
Summary:
Error Cause: The rustc_codegen_spirv build script requires a specific Rust toolchain version, which does not match the version specified in rust-toolchain.toml.
Standard Output: A notification to rerun the build if the environment variable RUSTGPU_SKIP_TOOLCHAIN_CHECK changes.
Standard Error: Clearly states the toolchain mismatch as the cause of the build failure.

Hmm, I am on the same OS version with a M1 Pro and can't repro. I get a different (known, #29) error which can be worked around with --release:
cargo run --release --bin example-runner-wgpuI have tried this with --release and still it fails with the same error.

This is the error:
error: building from local source while
REQUIRED_RUST_TOOLCHAIN(defined incrates/rustc_codegen_spirv/build.rs) doesn't match/Users/nilg/Workspace/Code/Rust/rust-gpu/rust-toolchain.toml
Maybe we should put it on multiple lines and/or use cargo::error to make this error more legible.
There is no crash at any point, so the OS or suggestions to use --release aren't relevant (or, well, they might be if you actually managed to build rustc_codegen_spirv).
I have no idea what state your code is in, but please make sure that crates/rustc_codegen_spirv/build.rs' const REQUIRED_RUST_TOOLCHAIN's contents are included in /Users/nilg/Workspace/Code/Rust/rust-gpu/rust-toolchain.toml.
On main these are:
rust-gpu/crates/rustc_codegen_spirv/build.rs
Lines 12 to 15 in 82a0f69
Lines 1 to 4 in 82a0f69
One or the other is likely changed locally for you, hence the error.
@nilanjan did you by any chance install Rust with brew? (I had similar issues when first building RustGpu projects, but uninstalled the brew one and then reinstalled via the official install script and all is well.)
I was able to install rust by following similar steps. Thanks for your input.

@eddyb perhaps offering a Rust install via the official script (as opposed to homebrew) as a solution will allow us to close this one?
