One thing I notice is that you have in your csproj:

<NativeFileReference Include="$(SkiaSharpStaticLibraryPath)\3.1.34\st\*.a" />

Note the st, but in the logs you have mt:

C:\Users\kirea.nuget\packages\skiasharp.nativeassets.webassembly\2.88.4-preview.70\buildTransitive\netstandard1.0....\build\netstandard1.0\libSkiaSharp.a\3.1.34\mt\libSkiaSharp.a

Not saying this is the issue, but it is something I noticed.

mattleibow · 2023-06-16T17:09:58Z

That type seems to be a part of .NET itself... https://github.com/search?q=org%3Adotnet%20emscripten_longjmp&type=code

mattleibow · 2023-06-16T17:21:31Z

https://github.com/emscripten-core/emscripten/blob/51b99e19f63896f681cdc714c62a3bbcbbef2690/ChangeLog.md#3132---021723

SUPPORT_LONGJMP's default value now depends on the exception mode. If Wasm EH (-fwasm-exception) is used, it defaults to wasm, and if Emscripten EH (-sDISABLE_EXCEPTION_CATCHING=0) is used or no exception support is used, it defaults to emscripten. Previously it always defaulted to emscripten, so when a user specified -fwasm-exceptions, it resulted in Wasm EH + Emscripten SjLj, the combination we do not intend to support for the long term.

And also emscripten-core/emscripten#19004

mattleibow · 2023-06-16T17:34:30Z

Can you also attach a binlog so we can investigate?

Yes, I accidentally attached the build output with mt when I tried this. With st the situation is the same. I corrected the build output in Issue.

The PR from @jeromelaban may fix this issue. It is still in the queue, but when it is done you can try using the PR artifacts.

Thanks for finding this!

Sure, I will try this, when the artifacts will be ready.
