Android AOSP构建在MacOS 10.14上失败

Question

不确定如何分类。我正在尝试在MacOS 10.14下从头开始构建AOSP。

我构建了区分大小写的文件系统，并执行了以下命令：

repo init -u https://android.googlesource.com/platform/manifest
repo init -b android-9.0.0_r34
repo sync
source build/envsetup.sh
lunch aosp_arm-eng
make -j4

并且还编辑了build / soong / cc / config / x86_darwin_host.go，以将10.14添加到darwinSupportedSdkVersions中。

构建因以下错误而失败：

为奥利奥（Oreo）建设也失败了，但方式不同。

知道我在做什么错吗？

尝试安装Xcode 9.4或更早版本，然后重新构建。希望这对您有帮助。

参考：https : //developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes

macOS 10.14 SDK不再包含对编译32位应用程序的支持。如果开发人员需要针对i386进行编译，则需要Xcode 9.4或更早版本。（39858111）
