foundry-zksync: zkforge zkbuild Error: Failed to compile smart contracts with zksolc

Hey folks 👋

We are in the process of releasing a new version of our Foundry implementation that will handle these situations much better. I apologize for the inconvenience currently being experienced, as this is an early alpha version we appreciate the reported issue. We are tracking to make a pre-release of the new version this week.

@yohanelly95 What I see you tried to specify zksol compiler with --use option. But this option is for sol compiler, see zkforge zkbuild --help. Try to use --use-zksolc instead. And, also, if I am not mistaken you can’t currently specify the path to the zksol compiler (despite --help saying it), only the version is supported.

@yohanelly95 Try to remove the zkout in the project with contracts, that appear after zkforge zkbuild and contain artifacts. Remove zksolc compiler, which should be at ~/.zksync/zksolc-<OS>-<ARCH>-<ZKSOLC_VERSION>. And try to rebuild with specifying options --use and --use-zksolc. In my case I’ve used zkforge zkbuild --use 0.8.13 --use-zksolc v1.4.0.

when I run zkforge zkbuild --use 0.8.13 --use-zksolc v1.4.0 I get the error

Message:  called `Result::unwrap()` on an `Err` value: Error("missing field `contracts`", line: 1, column: 3944)

This is a bug. Consider reporting it at https://github.com/foundry-rs/foundry

I have shared the repo details in the message above @OmegaTymbJIep

I have the exact same error running zkforge test (I assume it throws during a compilation phase!).

The problem occurs during just running zkforge test in a newly scaffolded project (ran zkforge init sampletest to generate a new project).

same here, the error comes up when running zkforge commands in a scaffolded project. In my case bridge_v2

When will it be solved?

@OmegaTymbJIep I see, what is the fix/workaround required then? This error persists

Error: 
Failed to compile smart contracts with zksolc: Could not assign standard_json to writer

Issue seems to occur with all zkforge related commands. How do I fix this compiler issue? @bxpana
