When I'm trying to build

compose-imageviewer

from

kotlin-wasm-examples

I'm getting

java.lang.IllegalStateException: e: Could not find "/home/me/kt/kotlin-wasm-examples/compose-imageviewer/shared/build/kotlinTransformedMetadataLibraries/jsWasmMain/org.jetbrains.skiko-skiko-0.0.7.80-wasm01-jsWasmMain-mF0BDQ.klib" in [/home/me/.local/share/kotlin/daemon]

but if I check this path I can see that file, with the same name... any ideas?

What kotlin version do you use? Please try with the latest commit in the main branch - https://github.com/Kotlin/kotlin-wasm-examples/commit/053feef9962718138ab723fbf8199e204a817052

gradle.properties shows

kotlin.version=1.9.20-RC

I am using latest commit, I'm using Ubuntu if that's important

hm. I'm on Ubuntu too. Tried to run it again right before commenting here.

./gradlew wasmJsBrowserRun

what gradle task do you run? Do you simply run or doing something else?

I'm running

build

from

imageviewer

project (directly from intellij). all other projects are building fine, but that

shared

one fails in

compileJsWasmMainKotlinMetadata

because of that one file

I see. Adding this in shared/build.gradle.kts should help:

project.tasks.whenTaskAdded {
        if (name == "compileJsWasmMainKotlinMetadata") {
            enabled = false
        }
    }

So let me give you some background, because maybe that's not the main issue: I tried to run

wasmJsBrowserRun

task and it works fine. The problem is that none browser actually works. In firefox I'm getting

wasm validation error: at offset 406: bad type

and in chrome

WebAssembly.instantiateStreaming(): invalid value type 0x71 @+405
CompileError: WebAssembly.instantiateStreaming(): invalid value type 0x71 @+405

the latest kotlin/wasm requires a dev/nightly version of Chrome (probably for firefox too) https://www.google.com/chrome/dev

Ok, that worked for Chrome. Thanks a lot! I didn't know that nightly builds are required because GC options are there in release builds

1.9.20-RC uses new wasm opcodes which are currently supported only in Chrome 119 and newer (dev and beta, iirc)

Is this mentioned anywhere in documentation? I missed that info or it's not mentioned since it's experimental feature and there is no need to document everything? I think it would be nice to at least add it to the repository readme.md

you are right, we'll mention it in readme.md

Awesome! And thank you once again with that problem!
