编译RiceDroid(Android13)针对Mi A1(tissot)时遇PATH_OVERRIDE_SOONG变量错误

问题重现 #

编译适配小米A1（tissot）的Android 13版RiceDroid时，触发Soong构建失败：

[100% 1/1] analyzing Android.bp files and generating ninja file at out/soong/build.ninja
FAILED: out/soong/build.ninja
cd "$(dirname "out/host/linux-x86/bin/soong_build")" && BUILDER="$PWD/$(basename "out/host/linux-x86/bin/soong_build")" && cd / && env -i  "$BUILDER"     --top "$TOP"     --soong_out "out/soong"     --out "out"     -o out/soong/build.ninja --globListDir build --globFile out/soong/globs-build.ninja -t -l out/.module_paths/Android.bp.list --available_env out/soong/soong.environment.available --used_env out/soong/soong.environment.used.build Android.bp

已尝试在config/BoardConfigSoong.mk添加以下代码，但无效：

PATH_OVERRIDE_SOONG := $(shell echo $(TOOLS_PATH_OVERRIDE))

可行修复方案 #

• 全局导出变量到Soong

  1. 打开build/make/core/config.mk，添加变量定义：

     PATH_OVERRIDE_SOONG := $(TOOLS_PATH_OVERRIDE)
     

  2. 打开build/make/core/soong_config.mk，添加变量导出规则：

     SOONG_CONFIG_VARS += PATH_OVERRIDE_SOONG
     

• 直接修正出错的Android.bp
  打开vendor/lineage/build/soong/Android.bp，定位到第24行的generated_kernel_includes模块，将$(PATH_OVERRIDE_SOONG)替换为$(TOOLS_PATH_OVERRIDE)；若编译环境无需路径覆盖，可直接删除该变量引用。

• 校验源码完整性
  执行以下命令重新同步完整源码，避免LineageOS相关补丁缺失：

  repo sync -c -j$(nproc --all) --force-sync --no-clone-bundle --no-tags
  

验证步骤 #

修改完成后，清理构建产物并重新编译：

make clean
source build/envsetup.sh
lunch ricetissot-userdebug
m -j$(nproc --all)
