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.shlunch 21make -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：

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 flashallerror: neither -p product specified nor ANDROID_PRODUCT_OUT setSuperli-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.shlunch 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~
