Fatal Error

[TeamPuzel]

That's all I see when trying to use carton dev, even when using the templates

[kateinoigakukun]

Sorry for your inconvenience. I'd like to know more details about your situation because I can't reproduce your issue on my side.

1. Which version of carton are you using?
2. Which OS and OS version are you using?
3. Please report the exact command output you got.

[TeamPuzel]

Hey,
I'm using the version installed with brew, I'm on the latest dev beta, but a while ago I tried on Monterey too

The problem is, there is no output

[kateinoigakukun]

Could you try with --verbose option and tell me the output?

[TeamPuzel]

hm it looks like Foundation on 13 requires swift 5.7?

I tried using the 5.7 toolchain but it also failed

[mustiikhalil]

I think I'm facing the same issue, and a bit of digging gave me this; error

I think the issue comes from our use of libSwiftPM - on macOS it defaults to use the toolchain provided by xcrun vs our toolchain. We have an imminent fix for Xcode 14/Swift 5.7 but we should look into fixing it in a more resilient way.

[mustiikhalil]

I've tried compiling the new solution from source, however it seems that the issue still persists. Not sure if I'm doing something wrong from my end though

Fixed, by re-downloading the 5.7 sdk.

[gmondada]

I downloaded the 5.7 with:
carton sdk install wasm-5.7-SNAPSHOT-2022-11-09-a

I created a .swift-version file with wasm-5.7-SNAPSHOT-2022-11-09-a inside.

Now carton dev goes further but in Safari console I get:

Error: JavaScriptKit supports only WASI reactor ABI.
                Please make sure you are building with:
                -Xswiftc -Xclang-linker -Xswiftc -mexec-model=reactor

Tested with carton 0.17 built from source code and it works.

[kateinoigakukun]

Version 1.0 rewrote the dev server with better error diagnostics. Could you try again with the new version? Please re-open if you still have any issues.
