library dependency of solana-frozen-abi 1.17.13 breaks build-sbf

[marshallr12]

Problem

ahash v0.8.7 uses an unstable feature which breaks cargo build-sbf on Solana v1.17.13. ahash is a dependency of solana-frozen-abi.

For more information about this error, try `rustc --explain E0658`.

Proposed Solution

Not sure. Maybe ahash needs to be fixed by adding the crate attribute.

I'm hitting the same issue (OSX)

The easiest way to fix this problem is to add:

ahash = "=0.8.6"

to your dependency list in Cargo.toml

or run:

cargo update -p [email protected] --precise 0.8.6

Neither of those solutions worked for me with Rust 1.75.0 .

What do you get if you run cargo tree -i ahash?

Also, your Rust version is irrelevant because rustc in cargo-build-sbf is coming from Solana's fork (#31428).

[marshallr12]

After running cargo tree and getting 0.8.7, I realized I made a mistake and added ahash="=0.8.6" to my workspace Cargo.toml dependencies instead of my solana program's Cargo.toml. After I fixed that, I got things to compile correctly.

Also, your Rust version is irrelevant because rustc in cargo-build-sbf is coming from Solana's fork (#31428).

Well, that makes sense since cargo build worked fine. Thanks for your help!

Looks like this got fixed in #34636 and #34650 so this issue can be closed.
