error: could not compile `spl-token-confidential-transfer-proof-generation` (lib) due to 6 previous errors
warning: build failed, waiting for other jobs to finish...

solana-program-library on  master [!] via ⬢ v22.8.0 via 🦀 1.82.0 took 13.0s

However, running the following:

cargo build --package spl-token-2022@4.0.0 --target wasm32-unknown-unknown

Compiles with no errors.

This is preventing my upgrade to v2 (https://github.com/ifiokjr/wasm_solana/pull/20) in wasm_client_solana. Browser tests fail to compile since the target is wasm32-unknown-unknown.

[joncinque]

@samkim-crypto can you look into this one?

[ifiokjr]

This is now fixed when using solana-*@2.1.2.

Thanks!
