1、文本解析错误
TOYBOX_VERSION awk: bailing out at source line 1
解决：使用gawk替换awk
brew install gawk
2、MacOS SDK版本问题
在较新版本的mac系统下编译aosp可能会出现MAC_SDK_VERSION ${版本号} isn't supported ...或者MAC_SDK_VERSION 10.13 is not installed.
aosp所使用的sdk版本一般都很低，这里为了编译通过我们需要下载旧版本的sdk。
旧版本下载地址：https://github.com/phracker/MacOSX-SDKs
下载旧版本的sdk解压到/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/
修改xcode的最低SDK支持版本
cp /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/info.plist ~/Downloads
编辑文件~/Downloads/info.plist，将MinimumSDKVersion的值改为10.11,编辑完成后，再复制回去
推荐使用
vscode进行编辑，需要安装扩展Binary Plist
sudo cp -f ~/Downloads/info.plist /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/info.plist
完成，最后编译时指定下sdk版本MAC_SDK_VERSION=10.13即可：
MAC_SDK_VERSION=10.13 make -j8
如果需要自定义sdk版本的可以修改build/soong/cc/config/x86_darwin_host.go文件，进行以下修改：
darwinSupportedSdkVersions = []string{
"10.10",
"10.11",
"10.12",
"10.13",
"10.14", // 新增
"10.15", // 新增
"11.0", // 新增
"11.1", // 新增
"11.3", // 新增
}
在最新版本的源代码中，官方已经开始支持11.0和11.1的版本：https://android.googlesource.com/platform/build/soong/+/refs/heads/master/cc/config/x86_darwin_host.go
3、SELinux问题
错误日志：
[ 0% 4/29298] build out/target/product/keyaki/obj/ETC/sepolicy_tests_intermediates/sepolicy_tests

类似
FAILED: build out/target/product/${设备名称}/obj/ETC/sepolicy_tests_intermediates/sepolicy_tests
这样开头的错误基本属于SELinux的异常
临时解决方案：
make SELINUX_IGNORE_NEVERALLOWS=true
但是只是临时方案，关闭了SELinux功能，但是发布aosp版本时是需要打开的
修改文件system/sepolicy/tests/Android.bp，注释掉第14行的stl:"libc++_static",
@@ -11,7 +11,6 @@
