Compilation failed using docker

[CeSun]

I am adapting the Avalonia framework for HarmonyOS Next. Now a crash occurs in the SkiaSharp native library. I want to debug the SkiaSharp native library, so I need to compile libSkiaSharp.so

tag: v2.88.9

Also I want to ask, how to compile binary for arm64-musl via docker?

To target arm64-musl I think you need a variant that builds against this arch.

As far as I can see this is not specifically built for when looking here: https://github.com/mono/SkiaSharp/blob/main/scripts/cake/native-shared.cake#L100

I'd think if you have the native bits build the correct RID, the dotnet part should just run on that platform but not 100% sure.

In fact,I'd like to know why it fails even though I follow the tutorial step by step.

I made it!But the document might need a few minor reminders.

Please let me know what I was missing so we can all get out Linux build experience to be amazing :)
