0.6.1 compiles without errors.

Nighly Rust (required by current Anchor) setting is: RUSTUP_TOOLCHAIN=nightly-2024-11-19

Gm @mikemaccana thanks for raising that the lint reason doesn’t play nice with the Anchor specified nightly Rust. We’ll move the reasonto a comment to get this unblocked, stay tuned.

Actually, i’m unable to reproduce the build error with RUSTUP_TOOLCHAIN=nightly-2024-11-19. Can you please try building this toy project that uses pyth-solana-receiver-sdk==v1.0.0?

I’m attaching my output of running RUSTUP_TOOLCHAIN=nightly-2024-11-19 anchor build --no-idl.

(I used --no-idl because there are some incompatibilities with Anchor and proc-macro2 in the IDL generation step)

Same issue for me unfortunately.

We removed the lint reason in v1.0.1, can you please try that version?
