新世界的SkiaSharp和HarfBuzzSharp进度如何

普通Linux小白

如题

普通Linux小白

RISC-V都支持了
https://github.com/mono/SkiaSharp/commit/e5f74e7db54c7225297bbec62c7de89c4212be2b

xen0n

目前没人提，需要有人去仿照 RISC-V 的支持请求，给龙架构也建立一个 issue，然后自己做或者摇人做

affoto

xen0n 这个可以考虑一下，支持！

普通Linux小白如果没记错的话你自己有 GitHub 账号，如果你对这件事最有热情那么大概不需要麻烦别人。不会写的话，大可打开 DeepSeek 帮忙润色

普通Linux小白

我准备亲自动手写了，仿照RISC-V格式

普通Linux小白

我只是仿照了RISC-V那个issue的写法，触发了bot相似度检查
但是LoongArch是完全独立的指令集

普通Linux小白

普通Linux小白由于debian尚缺乏loong64的gcc-cross导致docker构建失败，我只能暂时关闭PR

普通Linux小白

普通Linux小白
 https://ftp.debian.org/debian/pool/main/g/gcc-14-cross-ports/
准备重新构建

普通Linux小白

没有必要拉踩吧，我又重新开启了PR

普通Linux小白

我那边仿照SkiaSharp RISC-V支持的SkiaSharp龙架构新世界支持准备并入主线，问一下各位还有没有要修改的
https://github.com/mono/SkiaSharp/pull/3198

可能的优化：

debian 13 代号 trixie 而不是 loongnix 25
loongnix 25 是使用的 sid 源还是 trixie 源构建的可能要自己自测下。

可能的修复：
scripts/Docker/debian/clang-cross/13/Dockerfile，需要适配其他架构，而不是只能构建 loong64 的包。
否则代码应该存放到 scripts/Docker/loongnix/loong64/Dockerfile

另外 amd64/debian:12 并不存在 libstdc++-dev-loong64-cross libgcc-14-dev-loong64-cross binutils-loongarch64-linux-gnu 这些包

至少需要 amd64/debian:trixie，但是目前 amd64/debian:trixie 属于 testing

项目相关开发人员给出的建议是比较合理的。

下面是我自己写的一个 patch，未验证。供参考
cat loong64.patch

而且现在项目调整了目录结构，你可能要重新提交下。
