I'm trying to run a CPI example of Raydium AMM https://github.com/raydium-io/raydium-cpi-example/blob/master/amm-cpi/

All settings are the same as in GitHub repo.

[dependencies]
anchor-lang = "0.29.0"
anchor-spl = "0.29.0"
amm-anchor = { git = "https://github.com/raydium-io/raydium-contract-instructions", package = "amm-anchor" }
solana-program = ">=1.16, <1.18"

It seems that dependencies versions are wrong.

Cargo.lock

[[package]]
name = "solana-program"
version = "1.16.25"
source = "registry+https://github.com/rust-lang/crates.io-index"
...

[[package]]
name = "solana-program"
version = "2.0.11"
source = "registry+https://github.com/rust-lang/crates.io-index"

I found that people are playing with versions to solve this problem, but since my experience with Rust and Solana is very low I don't know what versions they are using. And how do they downgrade dependencies that are automatically loaded from other dependencies?

edit: compiled the amm-cpi example using the versions below with no errors.

anchor-cli 0.28.0
solana-cli 1.17.34 (src:b04a806c; feat:3746964731, client:SolanaLabs)

It's not just what's in your Cargo.toml you might also need to update your lock file,

In a previous project, downgrading one dependency causes a chain reaction where you'll need to downgrade a bunch of other crates which is impossible to know beforehand the ones that'll be affected.

Here is a working lock file https://gist.github.com/jim4067/d251f8b93dd28864c497824ae22e39bd

  • I've installed the same environment as yours. Can you please share the command you use to build amm-cpi since whenever I run [anchor build] it updates Cargo.lock file

  • delete the target folder update your lock file with the one in the gist, save and then build

  • Thanks for your time, but still there is a problem my@MBP amm-cpi % rm -rf target my@MBP amm-cpi % rm Cargo.lock my@MBP % cp Cargo.lock.Jimii Cargo.lock my@MBP % anchor build error: package num_enum_derive v0.7.3 cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.68.0-dev Either upgrade to rustc 1.70.0 or newer, or use cargo update -p [email protected] --precise ver where ver is the latest version of num_enum_derive supporting rustc 1.68.0-dev You removed num_enum_derive v0.7.3, but the build overwrite Cargo.lock

  • Looks like you are going to update the crates that are causing the issues. Start with cargo update -p [email protected] --precise 0.7.0

  • That's because of the requirement of spl-token-2022 which was overwritten in a lock file after anchor build. Can you please share your Cargo.toml file?
