给龙芯 loong64 移植思源笔记

最近在使用龙芯 3A5000, 但是苦于寻找开源的可以自己编译的笔记软件。寻找了不少开源产品比如 Anytype。但都因为依赖过于复杂，无法很好的移植在龙芯平台上运行 QAQ

好在最后尝试了一下思源笔记的编译，比较顺利地完成了，简单分享一下编译过程：

1. 第一步，获取源码，可以在 github 上直接获取： https://github.com/siyuan-note/siyuan

2. 设置龙芯可以使用的 electron 源：

   export ELECTRON_MIRROR=https://github.com/darkyzhou/electron-loong64/releases/download/
   export electron_use_remote_checksums=1 
   ​

3. 由于平台支持原因，此时不能直接执行 pnpm install，需要安装有编译好的龙芯版本的 electron：

   pnpm install electron@v35.4.0 -D
   ​

4. 下一步是安装修改过的 electron-builder，以支持龙芯 CPU 的构建

   "devDependencies": {
   +    "@darkyzhou-powered/electron-builder": "25.1.8",
   -    "electron-builder", "xxxx.xxx.xxx"
   }
   ​

5. 此处修改后进行 pnpm install，可能会出现依赖问题，按照提示降级即可，暂时未出现问题

6. 编译 kernel，在执行 build 之前，修改 kernel 目录下的 go.mod，更改如下：

   +	github.com/go-ole/go-ole v1.3.1-0.20250305162226-6867ec158e36
   -	github.com/go-ole/go-ole v1.3.0
   ​

   老版本依赖不支持 loong64 架构，新版添加了支持。由于 siyuan 仓库未更新，只好手动更新一下。 更新完成后，即可使用 cd kernel && go build --tags "fts5" -o "../app/kernel-linux-loong64/SiYuan-Kernel" 进行构建了。

7. 随后，重新切换到 app 目录下，创建一个名为 electron-builder-linux-loong64.yml 的文件，内容如下：

   appId: "org.b3log.siyuan"
   asar: false

       }
     }
     extraResources:

       # - target: "AppImage"

     - from: "appearance/fonts"
       to: "appearance/fonts"
       filter: "!**/{.DS_Store}"
     - from: "pandoc/pandoc-linux-loong64.zip"
       to: "pandoc.zip"
   
   ​

8. 注意：对于龙芯平台上运行构建，其中，压缩 tgz 用到了 7zip，由于随包分发的 7za 不支持 loongarch64，因此需要手动替换一下：cp /usr/bin/7za app/node_modules/.pnpm/7zip-bin@5.2.0/node_modules/7zip-bin/linux/loong64。请根据实际情况创建文件夹！其次，deb 打包由于使用了第三方可执行文件，暂时没有龙芯架构的可执行文件，要想成功打包 deb 可能需要 latx 二进制翻译的支持。交叉编译时无需关注。

9. 修改 package.json，添加我们自定义的构建配置：

    "scripts": {
       "dist-linux-loong64": "ELECTRON_MIRROR=https://github.com/darkyzhou/electron-loong64/releases/download/ electron-builder --linux --config electron-builder-linux-loong64.yml --publish=never"
     }
   ​

10. 最后，执行 pnpm run build && pnpm run dist-linux-loong64 就可以完美打包啦~
