Error: failed to run cargo-build-bpf for `ring v0.17.8`

help

Hi, guys. I've been trying to compile a program using cargo-build-bpf for hours and I get this error. I still don't know what could be wrong with this crate. My CPU is x86_64

The following warnings were emitted during compilation:

I suspect ring being one of the crates that fall under the restrictions of the solana bpf target. There might be other crates providing the cryptographic algorithms you need and work on the target though.

The problem here is that I don't use ring directly, I think the crate solana-config-program uses it under the hood. I removed the crate and it compiled, but there're some functions that I'd like to implement in my smart contract.

This is my cargo.toml

[features]

no-entrypoint = []

[dependencies]

solana-program = "2.0.9"

borsh = "1.5.1"

thiserror = "1.0.63"

serde = { version = "1.0.145" }

getrandom = { version = "0.1.14", features = ["dummy"] }

solana-config-program = "2.0.9"

[lib]

crate-type = ["cdylib", "lib"]
4

I'm pretty sure solana-config-program (which depends on solana-sdk) is meant for off-chain stuff and not for your on-chain program you compile for BPF:

This is the base library for all off-chain programs that interact with Solana or otherwise operate on Solana data structures. On-chain programs instead use the solana-program crate...
