Android Soong缺少android.PathForSourceRelaxed和ctx.Config().BuildOSTarget

大家好，我们又见面了啊~本文《Android Soong缺少android.PathForSourceRelaxed和ctx.Config().BuildOSTarget》的内容中将会涉及到等等。如果你正在学习Golang相关知识，欢迎关注我，以后会给大家带来更多Golang相关文章，希望我们能一起进步！下面就开始本文的正式内容~

我正在尝试编译纯 aosp 源代码并不断收到这两个错误。我正在使用沿袭供应商文件并使用 aosp 设备树 附：我正在使用实时系统，但问题是有两个未定义的方法

解决方案

我正在使用类似的参数进行构建（aosp 基础、los 设备、通用板和内核树，并使用 vendor/lineage 获取一些配置）。我只遇到了这个error：

vendor/lineage/build/soong/generator/generator.go:229:38: undefined: android.PathForSourceRelaxed

经过一番调查，我发现 pathforsourcerelaxed 是在 this commit 中的 los build/soong/android/paths.go 上定义的函数。

关于 buildostarget，我发现它在 build/soong/android/config.go 上定义，包含在 this commit 上。但是，当我查看 aosp 11.0.0_r24 标签源代码时，它已经存在（它是我用作基础的标签）。 p>

编辑：

将这些提交包含在 aosp 基础中的一种可能方法是遵循此 gist。基本上，您将执行以下操作：

• cd project_you_need_fixes，以便您转到正确的项目；
• git remote add 为项目添加远程（我个人喜欢这样使用它：git remote add git@github:someone/somerepo -tbranch_i_wish_to_clone 因为如果你愿意的话，你可以使用 - 来跟踪一个分支- t 标志）；
• git fetch --all 确保获取所有内容；
• gitbranch --track local_branch_name_of_the_one_you_want_to_track remote_you_just_added/branch_you_want_to_track 创建分支；
• git pull，以便合并提取的更改（如果有）。

然后您需要挑选解决问题所需的提交。如果是 pathforsourcerelaxed，则需要从 los 存储库中进行挑选：

• git status 或 gitbranch 以确保您位于自己的分行，而不是从 los 获取的分行；
• gitcherry-pick 191bf4e250d097995a2d55e5ca464ffd022b5baa（考虑到您提取了 lineage-18.1 分支。
