android源码编译 坑

-bash: lunch: command not found

先调用

. build/envsetup.sh

再执行

Can not find SDK

Can not find SDK 10.6 at /Developer/SDKs/MacOSX10.6.sdk

网上说法: 把 ==build/core/combo/mac_version.mk== 中的 ==mac_sdk_versions_supported== 版本问题, 只要修改一下, 对应你的 ==/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs== 下面 MacOSX 版本就行了.
但是我这边试了并不行, 还是得屁颠屁颠跑去下载了低版本 SDKs.

然而下载 10.6 版本会出现下面这个问题

DVTSDK: Skipped SDK xxxx; its version (10.6) is below required minimum (10.11) for the macosx platform.

说最少得用 10.11 版本... 好吧, 下载 10.11 版本

DVTSDK: Skipped SDK /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk; its version (10.9) is below required minimum (10.11) for the macosx platform.

如果你 SDKs 里面有 10.6 还是会提示一大堆东西 ( 是默认优先去加载 10.6 了??? ), 这个时候, 只要把10.6 移除就行了.

JDK

Unable to find any JVMs

该问题是找不到java版本

Unable to find any JVMs matching version "1.7". 

可以先 open /Library/Java/JavaVirtualMachines/
看一下你本机是否有JDK了, 如果没有或者版本比Android源码要求的高, 都去下载, 然后把该 openjdk/Contents/Home 放到环境内 ~/.bash_profile

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
export ANDROID_JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home

tools.jar

找不到 tools.jar, 因为一开始我用的是 12.0.1 版本, 在 JDK9 的时候, 官方就移除了 tools.jar
所以我们要下载 JDK8, 然后把相对应的 tools.jar 移过来就行 然而经自己测试了一下, 还是有问题, 所以不要搞啥花里胡哨的, 直接下载 JDK 7 (源码对应JDK)

Error: could not find jdk tools.jar

The required version is: "1.7.x"

JDK 还是报错说不要用 12.0.1 版本, 这个下载 JDK 7 就行了

You are attempting to build with the incorrect version
of java.
 
Your version is: openjdk version "12.0.1" 2019-04-16 OpenJDK Runtime Environment (build 12.0.1+12) OpenJDK 64-Bit Server VM (build 12.0.1+12, mixed mode, sharing).
The required version is: "1.7.x"
 
Please follow the machine setup instructions at
    https://source.android.com/source/initializing.html

下载之后, 设置 ~/.bash_profile

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
export ANDROID_JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home

但是我碰到了, 设置还是不行
然后先查询现在的版本

/usr/libexec/java_home -V

设置版本
其实就是直接在当前命令窗口导入环境变量, 这个指标不治本, 后来自己再测了一下, 源码自己修改了 .bash_profile 文件, 但是没去导入它 (或者重新打开窗口), 这样环境变量就没有改变 =_=

export JAVA_HOME=`/usr/libexec/java_home -v 1.7.0_80`

再次, 查询, 很好, 当前环境变量已经调过来了, 然后继续执行 make -j4

java -version

bison

解决一

bison 有问题, 出现 Abort trap: 6
https://blog.csdn.net/camlot_/article/details/86540502
网站说的路径不太对, 最终自己找到的路径是 ==/opt/local/bin/bison== , 就是一开始配置环境 Macports 下载的时候, 会下到这个路径下
然而如果自己用 brew install Bison 就是在这个路径下 /usr/local/Cellar/bison/版本/bin/bison

prebuilts/misc/darwin-x86/bison/bison -d  -o out/host/darwin-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_y.cpp frameworks/base/tools/aidl/aidl_language_y.y

把 bison 创建一个快捷方式到某个路径下

ln -s 源文件路径 目标路径

解决二

编译 8.0 的时候查出来的

网上说到这个目录下, 然后更新指定 git 版本, 但是我这边根本更不了... .git 文件夹就是坏的

cd external/bison
git cherry-pick c0c852bd6fe462b148475476d9124fd740eba160

上面说的copy一个bison到这个文件夹, 也是不行的....
后面找到了这个, 自己去编译一个 bison 出来 (上面的 git cherry-pick 就是打补丁, 而这个是手动打补丁)
https://blog.csdn.net/h649305597/article/details/80322488

1. 到该文件夹下

cd external/bison

1. 创建 patch-high-sierra.patch

touch patch-high-sierra.patch

1. 并把下面代码复制进去

With format string strictness, High Sierra also enforces that %n isn't used
in dynamic format strings, but we should just disable its use on darwin in
general.

1. 在控制台（保证当前目录是external/bison）执行 (这个是打补丁的意思??)

patch -p0 < patch-high-sierra.patch

1. 返回源码根目录

cd ../..

1. 编译 bison

make bison

1. 复制编译好的 bison 到执行位置

cp ./out/host/darwin-x86/obj/EXECUTABLES/bison_intermediates/bison ./prebuilts/misc/darwin-x86/bison/bison

查了一下, 说需要换低版本XCode
下载 XCode 8.3.3, 好吧, 又是一阵等待
下载好之后, 选中 Xcode_8.3.3 为默认

sudo xcode-select -switch /Applications/Xcode_8.3.3.app/Contents/Developer

再次 make -j4

然而....又报错, 说不支持, 查了一下, 说 Mojave 不支持 10.0 以下的 XCode... oh my god! 很崩溃! 退版本这个是不存在的...
好吧, 有点绝望, 各种踩坑, 这个是弄了最久的, 网上各种资料, 都无法解决.

后来再自己仔细研究了一下, 其实这些报错, 是指向 XcodeDefault.xctoolchain

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/stdlib.h:118:42

那么是否能通过不替换XCode, 而是替换XCode下面的这个来作为一个中转方法呢???
测试了一下, 是可以了!! (≧▽≦)/

大致就是做两步

1. 下载 8.3.3 XCode
2. 把 8.3.3 XCode 的 XcodeDefault.xctoolchain, 放到现在的 XCode 中, 记得, 不要删除原有的, 以后还要继续用XCode呢, 备份一下. 然后替换掉就行.

在这里插入图片描述

目前使用下来, 是没发现有什么问题
这段时间没有打开XCode过, 不知道会影响 XCode 什么问题, 建议打开XCode 之前, 先把这个改回来.

• 解决方法：可以

  brew install curl --with-openssl
  

  来安装一个基于OpenSSL的curl，
• (如果上面的命令错误，使用brew install curl-openssl)。接着修改环境变量以使用新的curl:
• export PATH=$(brew --prefix curl)/bin:$PATH
• brew –prefix curl返回通过brew安装的curl的路径信息。
