Words between "(" and ")" is written by me, refers to the English of these Chinese words.
When I tried to compile an empty project with greeting words that comes with the avalonia template, no error occurs. I have installed the wasm workflow.
What should i do? Thanks!

Have you installed wasm-tools workloads? See https://docs.avaloniaui.net/docs/guides/platforms/how-to-use-web-assembly

[jyswjjgdwtdtj]

yes i have.

The log has things like lto.tmp: undefined symbol: gr_backendrendertarget_new_direct3d, etc which shouldn't make their way into a WASM build. Are you trying to use SkiaSharp 3? If so, have you explicitly included the SkiaSharp.NativeAssets.WebAssembly for the specific version?

WASM as an afterthought to an already made project is a bad idea, IMO. They're very tricky and have poor debugging information coupled with things that silently break. So you should always start out with a WASM project and work to keep it compatible since you can track regressions across version history.

I haven't noticed gr_backendrendertarget_new_direct3d at first, but it's a really good hint that you have a dependency not compatible with WASM leaked to the WASM build.
