Can't compile latest version

[nicosey]

Getting errors:

Compiling spl-zk-token v0.1.0 (/Users/nicosey/projects/spl-zk-token/program) error[E0609]: no field balance on type &solana_zk_token_sdk::instruction::CloseAccountData --> program/src/processor.rs:445:51	445	if zk_token_account.available_balance != data.balance {	^^^^^^^ unknown field

= note: available fields are: `pubkey`, `ciphertext`, `proof`

Any idea?

[samkim-crypto]

Yes, the code has not yet been updated for the latest zk-token-sdk. This should be fixed in a day or two.

@samkim-crypto Good to know as I started making local fixes but will just wait for this instead. Thanks!

[samkim-crypto]

The errors should be fixed.

In the future, as per the migration plan (https://github.com/solana-labs/spl-zk-token/issues/91), please refer to https://github.com/solana-labs/solana-program-library solana-program-library/token/program-2022/ for the most up-to-date zk-token program.

Grabbed latest and got the builds going but ran into an issue when trying to execute the demo, but it seems super close now if you can help me sort out the last issue...

solana_sdk::transaction::versioned::VersionedTransaction too large: 2640 bytes (max: encoded/raw 1644/1232

This error is basically expected at this point, unless you're running a local validator with this hacky patch: https://github.com/solana-labs/spl-zk-token/blob/master/scripts/0001-feat-double-PACKET_DATA_SIZE.patch

Work to enable larger transactions is still ongoing, which is a blocker for actually shipping zk-tokens

[sparkydasrath]

Thanks for the super fast update. Based on the setup file, the patch was supposed to get applied automagically so wonder why it didn't take. I will run just the section that deals with the patching and redo all the steps to see how far I get. This is cool stuff btw.

[sparkydasrath]

I got why the patch didn't run - I keep having issues running the setup script (github keeps complaining about access to solana) so I manually cloned the solana monorepo into the spk-zk folder and followed the rest of the steps - but skipping the patching part

[sparkydasrath]

New error now

[mvines]

This repo is in the process of being decommissioned (https://github.com/solana-labs/spl-zk-token/issues/91) Here's the new home for zk-token: https://github.com/solana-labs/solana-program-library/tree/master/token/program-2022/src/extension/confidential_transfer

The remaining bits in this repo, the tests and demo program, will be migrated to the new location pretty soon and then this repo will be deleted

[sparkydasrath]

Should I add this build issue over there then - would that be helpful or this is a known issue that will be sorted out soon enough?

[mvines]

It's a known issue, the demo/tests haven't been migrated yet. Thanks for your interest in this new feature though!

[harsh4786]

I've been waiting for this too,

Grabbed latest and got the builds going but ran into an issue when trying to execute the demo, but it seems super close now if you can help me sort out the last issue...
