Catalina编译android 10报错
环境
先声明一下环境：
系统： macOS Catalina 10.15.3
aosp分支版本：android-10.0.0_r21
编译目标版本：aosp_walleye-userdebug
当执行完编译相关命令后，最终执行make -j16的时候，出现了异常：
编译相关命令简介：
source build/envsetup.sh lunch 21 make -j16
异常一：系统不兼容
为了方便大家遇到的时候能搜到这里，我把整个异常的代码都贴出来：
Superli-2:aosp superli$ make -j16

解决方案
该问题是因为编译脚本中的内容和Catalina系统不兼容，google已经出了官方补丁，补丁地址。
要解决的同学，可以点进去看看，不过作为一个唯饭博客，我会直接告诉你怎么做。
用工具打开你的/system/sepolicy/Android.bp 这个文件，打开后长这样：
// libsepolwrap gets loaded from the system python, which does not have the
// ASAN runtime. So turn off sanitization for ourself, and use static
// libraries, since the shared libraries will use ASAN.
static_libs: [
"libbase",
"libsepol",
],
stl: "libc++_static",
sanitize: {
never: true,
},
}
将stl: "libc++_static",删除并保存即可。
然后再重新执行编译就行了。
保险起见，你可以把另一个补丁也加上，补丁地址。
用工具打开/build/soong/cc/config/x86_darwin_host.go，打开后长这样：
darwinSupportedSdkVersions = []string{
"10.10",
"10.11",
"10.12",
"10.13",
"10.14",
}
将它改为：
darwinSupportedSdkVersions = []string{
"10.10",
"10.11",
"10.12",
"10.13",
"10.14",
"10.15",
}
我用过这两个文件的修改后，编译一次成功。但愿你也是这样。
刷机fastboot 无法识别设备
执行 fastboot -w flashall或者fastboot devices的时候，出现如下异常：
ERROR: Couldn't create a device interface iterator: (e00002bd)
ERROR: Couldn't create a device interface iterator: (e00002bd)
ERROR: Couldn't create a device interface iterator: (e00002bd)
原因也是fastboot 版本不兼容。
解决 我将fastboot 版本替换为 26就可以了，如何更换？ 去这个地址：platform-tools_r26.0.1, 下载解压后，将一个名为fastboot的可执行文件替换到你当前的fastboot目录即可。
你可以通过
which fastboot看到你当前的fastboot地址。
找不到ROM位置
以上各种都解决完后，执行fastboot -w flashall刷机，出现找不到ROM位置的异常：
Superli-2:walleye superli$ fastboot -w flashall
error: neither -p product specified nor ANDROID_PRODUCT_OUT set
Superli-2:walleye superli$
或者说这种异常：
error: could not load android-info.txt
网上各种说法，都是让你去配置ANDROID_PRODUCT_OUT或者指定-p参数，但是并没有用。 如果你和我遇到的差不多，那可能是你当前的shell会话，没有执行环境初始化。
解决：我因为编译完后，中途退出了shell，重新打开准备刷系统，结果报了这个错。 只要重新初始化一下编译环境就可以解决：
source build/envsetup.sh
lunch 21
执行完后，再去对应目录刷系统，就可以成功了。``
差不多就这些了，Enjoy~
