New projects on anchor-cli 0.29.0 / solana-cli 1.17.17 still having ahash errors when building

[mikemaccana]

I did look for duplicates on this, but couldn't find any. Re rust-lang/rust#86161

ahash still seems to be failing in solana-cli 1.17.17, anchor-cli 0.29.0.

% anchor --version
anchor-cli 0.29.0

% solana --version
solana-cli 1.17.17 (src:27a43800; feat:1337574167, client:SolanaLabs)

% anchor init anchor-test --template=multiple

% cd anchor-test

error: could not compile `ahash` due to previous error

It's a duplicate of #2755 but Anchor doesn't even have a direct dependency to ahash, it's coming from Solana's side solana-labs/solana#34609.

I see in the logs you shared that it's compiling solana-frozen-abi v1.17.14 and ahash wasn't fixed on that version:

https://github.com/solana-labs/solana/blob/cc7c59af9f09932168bad4b3f94e3e09d336f6be/Cargo.toml#L135

It was fixed in the next release(1.17.15):

https://github.com/solana-labs/solana/blob/cc0e9a0e5a6b5c3e86d52ac105dac743826afd9a/Cargo.toml#L135

There is a solution I've posted in #2755 (comment) but in any case, pinning is only a short-term solution and problems like this will continue to happen as long as Solana's rustc is outdated solana-labs/solana#34609.

Edit: oh wait, there are two things were are discussing with similar versions, solana-frozen-abi v1.17.14 and solana-cli v1.17.17

---

If this was fixed in 1.17.15, I don't understand why it's occurring in 1.17.17.

I have heard (from you via Jacob) that cargo update will resolve this but running

cargo update
anchor init anchor-test --template=multiple
cd anchor-test
anchor build

Still produces this error.

[acheroncrypto]

Yes, the version I was talking about was from the logs you've shared:

% anchor build
   Compiling solana-frozen-abi v1.17.14

it's not your solana-cli version.

I have heard (from you via Jacob) that cargo update will resolve this but running

cargo update
anchor init anchor-test --template=multiple
cd anchor-test
anchor build

Still produces this error.

cargo update command needs to be run in a cargo workspace, not before the workspace is crated. It updates the dependencies to the latest SemVer compatible versions.

You can see which version of Solana crates you have by running:

cargo tree -i solana-program

You can also only update Solana deps with:

cargo update -p solana-program --precise 1.17.17

[mikemaccana]

Cool. I made another repo with a workflow to check Anchor is working out of the box though and I can see it works fine.

I can't update my own project right now (I have a deadline and my Anchor program breaks when I run cargo update -p solana-program --precise 1.17.17) but that's beside the point.

% cargo update -p solana-program --precise 1.17.17

perhaps a crate was updated and forgotten to be re-vendored?

solana-cli 1.18.0 which has a newer version of rustc got released so this particular error is not a problem anymore.
