AOSP 13编译失败：blueprint/pathtools测试报错求助

问题描述 #

使用16GB内存、12代酷睿i7的x64笔记本编译AOSP 13，已通过repo sync同步源码无报错，执行source build/envsetup.sh、lunch 47、m后，编译初期出现Blueprint Pathtools的TestGlobEscapes测试失败，多次执行repo sync和m clean无效。

解决办法 #

1. 调整字符集环境变量 #

字符集配置可能影响glob模式匹配行为，执行以下命令后重新编译：

export LC_ALL=C
m

2. 降低编译并行数 #

系统提示可用内存接近最低要求，减少并行编译任务数避免内存不足导致的异常：

m -j4

（可根据实际内存情况调整-j后的数字，比如-j2、-j4）

3. 删除Blueprint测试缓存 #

清理已生成的测试文件，重新触发测试编译：

rm -rf out/host/linux-x86/bin/go/blueprint-pathtools/test/
m

4. 临时跳过Blueprint测试（仅应急使用） #

修改build/blueprint/pathtools/Android.bp文件，注释掉测试相关的模块定义后重新编译。此方法可能影响后续依赖该工具的编译环节，仅建议在其他方法无效时尝试。
