前言

上章下完了代碼, 這章來搞編譯
編譯坑是最多的, 坑 我統一放在后面了, 如果遇到問題雹锣，可以先看一下是否我這邊已經有解決方法了.

在這里插入圖片描述

開搞它改，開搞.

AOSP系列

• 下載源碼
• 編譯源碼
• 模擬器啟動

開搞

自己的配置

硬件

8G 1600 MHz DDR3
自己換了三星的500G固態(tài)硬盤

軟件

源碼
版本: android-6.0.1_r78

JDK 7

android-6.0.1_r78 用的是 JDK 7

MacPorts

安裝了 MacPorts (看官網要求的遣妥， 也不知道不安裝會出現什么錯誤不, 當時沒試, 個人覺得不安裝, 應該也沒事, 比較官方的東西有點老)
通過 MacPorts 獲取 Make品姓、Git 和 GPG 程序包：

POSIXLY_CORRECT=1 sudo port install gmake libsdl git gnupg

安裝 bison：

POSIXLY_CORRECT=1 sudo port install bison

磁盤映像

因為Mac上的文件系統不能區(qū)分大小寫疆拘，所以需要創(chuàng)建區(qū)分大小寫的鏡像蜕猫。
打開磁盤映像
然后點擊空白映像, 配置如下, blog教程說至少70G, 我為了預防版本不同, 可能會包比較大問題, 直接分配100G了.
分配完成, 把源碼移動到磁盤內

在這里插入圖片描述

在這里插入圖片描述

分配的時候真的挺卡的...
可能因為我電腦配置太垃圾問題, 20 ~ 30分鐘才完成

雖然 blog 里面說, 先建磁盤, 但我個人建議, 先下載代碼, 然后看代碼有多大, 再去分.
不然分了磁盤, 再去磁盤里面下載, 但是你們版本不同, 包的大小也會不同
分配的盤裝不下, 這種情況就很尷尬.
所以我就將這步放在了編譯階段.

編譯

導入腳本環(huán)境

執(zhí)行 envsetup.sh 腳本

. build/envsetup.sh 

如果你再次編譯, 需要清除已編譯的數據, 可以調用以下命令

make clobber 

權限問題

當時下載源碼下來之后, 發(fā)現自己并沒有操作權限
如果有童鞋也和我一樣, 直接執(zhí)行這個, 把Android源碼這個文件夾改為所有人都可以讀寫

sudo chmod -R 777 源碼文件夾路徑

選擇要編譯的目標

命令行輸入

lunch

然后控制臺出現

Lunch menu... pick a combo:
     1. aosp_arm-eng
     2. aosp_arm64-eng
     3. aosp_mips-eng
     4. aosp_mips64-eng
     5. aosp_x86-eng
     6. aosp_x86_64-eng
     7. aosp_deb-userdebug
     8. aosp_flo-userdebug
     9. full_fugu-userdebug
     10. aosp_fugu-userdebug
     11. mini_emulator_arm64-userdebug
     12. m_e_arm-userdebug
     13. mini_emulator_mips-userdebug
     14. mini_emulator_x86-userdebug
     15. mini_emulator_x86_64-userdebug
     16. aosp_flounder-userdebug
     17. aosp_angler-userdebug
     18. aosp_bullhead-userdebug
     19. aosp_hammerhead-userdebug
     20. aosp_hammerhead_fp-userdebug
     21. aosp_shamu-userdebug

然后問你選擇哪一個, 直接輸入編號或者名稱都可以.
當然, 如果你已經知道編譯什么了, 也可以直接lunch帶上參數, 如下:

lunch aosp_arm-eng

開始編譯

開始編譯

-j4 是線程的意思, 并不是越多越好, 根據你機器cup的核心來確定: core * 2, 即當前cpu的核心的2倍, 是最快的速度.

make -j4

查看自己電腦的core

sysctl machdep.cpu

# 獲取到的信息
machdep.cpu.core_count: 2

那么我們就直接用 core * 2, 就是 make -j4

*** missing separator

不要在 . build/envsetup.sh 的窗口執(zhí)行, 在新的 shell 窗口執(zhí)行 (個人估計是一些環(huán)境變量原因)

dalvik/CleanSpec.mk:47: *** missing separator.

后來編譯完成之后, 發(fā)現新窗口的話, 編譯，總是 generic 文件夾, 這個不應該的
想了一下, 肯定是用新窗口, 然后編譯配置是用默認的了, 所以還是要解決這個方法
但是又找了好久, 沒找到解決, 不過可以通過另一種思路去搞.
其實調用 lunch xxx 這個是配置加載數據的意思, 那么我們是否能把配置數據復制下來, 然后寫到腳本內, 直接加載腳本呢, 達到直接配置的意思呢???
經過測試, 確實可以的

1. 例如我把 aosp_x86_64 復制, 并創(chuàng)建一個 xq_config_aosp_x86_64.sh 文件, 然后寫入以下內容

#!/bin/bash

export PLATFORM_VERSION_CODENAME=REL
export PLATFORM_VERSION=6.0.1
export TARGET_PRODUCT=aosp_x86_64
export TARGET_BUILD_VARIANT=eng
export TARGET_BUILD_TYPE=release
export TARGET_BUILD_APPS=
export TARGET_ARCH=x86_64
export TARGET_ARCH_VARIANT=x86_64
export TARGET_CPU_VARIANT=
export TARGET_2ND_ARCH=x86
export TARGET_2ND_ARCH_VARIANT=x86
export TARGET_2ND_CPU_VARIANT=
export HOST_ARCH=x86_64
export HOST_OS=darwin
export HOST_OS_EXTRA=Darwin-18.5.0-x86_64-i386-64bit
export HOST_BUILD_TYPE=release
export BUILD_ID=MOB31S
export OUT_DIR=out

2. 調用 make -j4 前, 導入配置

. 路徑/xq_config_aosp_x86_64.sh

3. 調用 make -j4

這個時候調用 make -j4 就能看到正常運行了, 并且能看到并不是只有 out/target/product/generic 了, 還創(chuàng)建了 out/target/product/generic_x86_64 文件夾

make -j4

大約編譯了兩個小時, out 文件夾下 6.14 G (看電腦配置)

最后終于大功告成, 編譯完成!!! 以下是成功信息

-bash: lunch: command not found

先調用

再執(zhí)行

Can not find SDK

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

網上說法: 把 ==build/core/combo/mac_version.mk== 中的 ==mac_sdk_versions_supported== 版本問題, 只要修改一下, 對應你的 ==/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs== 下面 MacOSX 版本就行了.
但是我這邊試了并不行, 還是得屁顛屁顛跑去下載了低版本 SDKs.

然而下載 10.6 版本會出現下面這個問題

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

說最少得用 10.11 版本... 好吧, 下載 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 還是會提示一大堆東西 ( 是默認優(yōu)先去加載 10.6 了??? ), 這個時候, 只要把10.6 移除就行了.

JDK

Unable to find any JVMs

該問題是找不到java版本

Unable to find any JVMs matching version "1.7". 

可以先 open /Library/Java/JavaVirtualMachines/
看一下你本機是否有JDK了, 如果沒有或者版本比Android源碼要求的高, 都去下載, 然后把該 openjdk/Contents/Home 放到環(huán)境內 ~/.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, 因為一開始我用的是 12.0.1 版本, 在 JDK9 的時候, 官方就移除了 tools.jar
所以我們要下載 JDK8, 然后把相對應的 tools.jar 移過來就行 然而經自己測試了一下, 還是有問題, 所以不要搞啥花里胡哨的, 直接下載 JDK 7 (源碼對應JDK)

Error: could not find jdk tools.jar

The required version is: "1.7.x"

JDK 還是報錯說不要用 12.0.1 版本, 這個下載 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

下載之后, 設置 ~/.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, 設置還是不行
然后先查詢現在的版本

/usr/libexec/java_home -V

設置版本
其實就是直接在當前命令窗口導入環(huán)境變量, 這個指標不治本, 后來自己再測了一下, 源碼自己修改了 .bash_profile 文件, 但是沒去導入它 (或者重新打開窗口), 這樣環(huán)境變量就沒有改變 =_=

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

再次, 查詢, 很好, 當前環(huán)境變量已經調過來了, 然后繼續(xù)執(zhí)行 make -j4

java -version

bison

解決一

bison 有問題, 出現 Abort trap: 6
https://blog.csdn.net/camlot_/article/details/86540502
網站說的路徑不太對, 最終自己找到的路徑是 ==/opt/local/bin/bison== , 就是一開始配置環(huán)境 Macports 下載的時候, 會下到這個路徑下
然而如果自己用 brew install Bison 就是在這個路徑下 /usr/local/Cellar/bison/版本/bin/bison

網上說到這個目錄下, 然后更新指定 git 版本, 但是我這邊根本更不了... .git 文件夾就是壞的

cd external/bison
git cherry-pick c0c852bd6fe462b148475476d9124fd740eba160

上面說的copy一個bison到這個文件夾, 也是不行的....
后面找到了這個, 自己去編譯一個 bison 出來 (上面的 git cherry-pick 就是打補丁, 而這個是手動打補丁)
https://blog.csdn.net/h649305597/article/details/80322488

1. 到該文件夾下

cd external/bison

2. 創(chuàng)建 patch-high-sierra.patch

touch patch-high-sierra.patch

3. 并把下面代碼復制進去

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.

4. 在控制臺（保證當前目錄是external/bison）執(zhí)行 (這個是打補丁的意思??)

patch -p0 < patch-high-sierra.patch

5. 返回源碼根目錄

6. 編譯 bison

查了一下, 說需要換低版本XCode
下載 XCode 8.3.3, 好吧, 又是一陣等待
下載好之后, 選中 Xcode_8.3.3 為默認

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

再次 make -j4

然而....又報錯, 說不支持, 查了一下, 說 Mojave 不支持 10.0 以下的 XCode... oh my god! 很崩潰! 退版本這個是不存在的...
好吧, 有點絕望, 各種踩坑, 這個是弄了最久的, 網上各種資料, 都無法解決.

后來再自己仔細研究了一下, 其實這些報錯, 是指向 XcodeDefault.xctoolchain

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

那么是否能通過不替換XCode, 而是替換XCode下面的這個來作為一個中轉方法呢???
測試了一下, 是可以了!! _(≧▽≦)/

大致就是做兩步

1. 下載 8.3.3 XCode
2. 把 8.3.3 XCode 的 XcodeDefault.xctoolchain, 放到現在的 XCode 中, 記得, 不要刪除原有的, 以后還要繼續(xù)用XCode呢, 備份一下. 然后替換掉就行.

在這里插入圖片描述

目前使用下來, 是沒發(fā)現有什么問題
這段時間沒有打開XCode過, 不知道會影響 XCode 什么問題, 建議打開XCode 之前, 先把這個改回來.

You have tried to change the API from what has been previously approved.

To make these errors go away, you have two choices:
   1) You can add "@hide" javadoc comments to the methods, etc. listed in the
      errors above.

   2) You can update current.txt by executing the following command:
         make update-api

      To submit the revised current.txt to the main Android repository,
      you will need approval.
