[FEATURE] linux-bionic flavor of libSkiaSharp and libHarfBuzzSharp

[aicynide]

Description

e.g. https://nuget.info/packages/SQLitePCLRaw.lib.e_sqlite3/2.1.11 doesn't have runtimes/linux-bionic . Something can be done for SkiaSharp. toolchains are available in modern ubuntu/debian, fedora and alpine.

for ref
ericsink/cb@fe4e425
ericsink/SQLitePCL.raw@685942a

ideally infra should be DRY'd so it's just a matter of adding a single line in shell or cake script for new platform: define_platform(dotnetArch, nativeArch, osName) {. ... expand ... } which will expand to rubberstamped stuff for clang -target .... e.g.

Code

existing

define_platform("arm64", "aarch64", "linux")
define_platform("arm64", "aarch64", "linux-musl")

for this feature request

define_platform("arm64", "x64", "linux-bionic")

linux-bionic isn't riscv64, it is implementation of C library for Android, primarily needed in Termux

Thanks for the issue. Do you have any idea how to build this? We got some cross Compiling going for musl and resc, is there a bionic compiler for debian?

Do you have any idea how to build this?

Sorry I don't, I have no knowledge about C#

off-topic

there is a first class build script to build dotnet for bionic. https://github.com/termux/termux-packages/tree/8f1eba3b48/packages/dotnet9.0/build.sh for dotnet v9
https://github.com/termux/termux-packages/tree/d11fb6d078/packages/dotnet8.0/build.sh for dotnet v8
(Other build script for aspnetcore, runtime, tageting-pack etc. - https://github.com/termux/termux-packages/tree/d11fb6d078/packages/dotnet8.0 )
If you are curious how is dotnet packaged for linux-bionic , look at the scripts & Dockerfile in this repo https://github.com/termux/termux-packages/

If cross compiled binary/library won't run in bionic, I think I've the idea how get it fixed, we can use termux/termux-docker:latest docker

While there maybe assumption that android-{arch} is same as linux-bionic-{arch} , there is huge difference b/w them, android-{arch} is only Mobile .Net stack but linux-bionic-{arch} is Full .Net Stack, consider it equivalent to linux-{arch}

Thank you

Any progress?

I would like to request the maintainer to research https://github.com/termux/termux-packages/ for linux-bionic-{arch} build

i'm not interested in linux-bionic, sorry.

We've found some similar issues:

your issue description is a copy of #3191 where i was making a point to show how it's implemented elsewhere and you copied it to make a point how it is not implemented? weird

#3197 is no different. both these requirements just happened to show up soon as i started the work. i'm not sure if this is some sort of a bot account campaign, but it's not rubbing me right

[aicynide]

Hello Mr. @kasperk81 , I'm legit human, I'm not bot, I've genuine reasons for the request I'm requesting for linux-bionic-arm64 because I'm a package maintainer in termux and I'm trying to package jellyfin which has SkiaSharp dependency.

The reason for my copying the issue it that I've zero knowledge of .Net/C# I apologize for that.
That's why I'm begging for linux-bionic-arm64 build

#3197 is no different. both these requirements just happened to show up soon as i started the work. i'm not sure if this is some sort of a bot account campaign, but it's not rubbing me right

This issue for Chinese processor is bot, I can cofirm, he's a 50 cent army of Chinese Communist Party. They are From CCP to IT Cell to spread technology propaganda of Chinese products
loongarch is made by CCP to attack Taiwan chip industry. Please ignore that issue, loongarch is a meme cpu

I hope you understand and can differentiate between a tech enthusiast and Chinese bot
