android4.1.1系統編譯全過程

一、編譯環境：首先介紹編譯中使用的工具：虛擬機器：    vmare 9 ：http://blog.csdn.net/hudan2714/article/details/7902654linux平台：ubuntu 12.04 64位jdk:              sun-java6-jdk （64位）交叉編譯工具鏈：gcc 使用的版本是：4.6.3 想要完成最終的編譯，當然首要的就是檢查環境：1、安裝的ubuntu設定空間大小：至少需要30G     目前下載的包就有10G：有圖有真相：              包括解壓編譯後大小有30G了：           所以空間一定要夠了才行。2、gcc和g++不能使用使用4.4版本了（編譯android4.0系統使用的是4.4），                       現在只要使用系統內建的4.6.3（ubuntu12.04） 就可以了。      3、jdk版本：sun-java6-jdk         二、編譯：        編譯過程不知道，可以查看官方文檔了。這裡做簡單說明：        1.source build/envsetup.sh   這是向系統匯入不同的廠商版本，並添加m命令。        2.lunch 選擇編譯廠商版本。        3.mm    編譯版本         還是看圖說話吧：                       當然這裡的lunch full-eng是編譯所有，如果嫌慢，就單獨編譯某一個也可。                           再mm就可以編譯了（必須要source了，才有mm命令，而且只在此terminal有效）                三、編譯中遇到的錯誤：       錯誤太多，做了一些總結，有點亂，如果編譯過程中遇到錯誤，可以來查看：/bin/bash: bison: command not foundmake: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_y.cpp] Error 127解決方案：sudo apt-get install bisonmake: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] Error 127解決方案： sudo apt-get install flexmake: *** [out/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/Source/WebCore/css/CSSPropertyNames.h] Error 25解決方案：sudo apt-get install gperf/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directoryIn file included from /home/hudan/android/source/android4.1.1/prebuilts/gcc/linux-x86/host/i686-linux-glibc2.7-4.6/bin/../sysroot/usr/include/sys/types.h:27:0,                 from frameworks/native/include/utils/Errors.h:20,                 from frameworks/native/include/utils/String8.h:20,                 from cts/suite/audio_quality/lib/include/Settings.h:21,                 from cts/suite/audio_quality/lib/src/Settings.cpp:17:/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directoryIn file included from /usr/include/stdlib.h:25:0,                 from cts/suite/audio_quality/lib/src/Adb.cpp:16:/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directorycompilation terminated.compilation terminated.compilation terminated.make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libcts_audio_quality_intermediates/src/SimpleScriptExec.o] Error 1make: *** Waiting for unfinished jobs....make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libcts_audio_quality_intermediates/src/Adb.o] Error 1make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libcts_audio_quality_intermediates/src/Settings.o] Error 1In file included from /usr/include/semaphore.h:22:0,                 from cts/suite/audio_quality/lib/include/Semaphore.h:21,                 from cts/suite/audio_quality/lib/src/Semaphore.cpp:17:/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directorycompilation terminated.make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libcts_audio_quality_intermediates/src/Semaphore.o] Error 解決方案：sudo apt-get install gcc-multilib 

error libGL.so: cannot open shared object file: No such file or directory

OSError: libGL.so: cannot open shared object file: No such file or directory

may appear on Linux systems when you try to launch VNL for the first time. To solve it, create (as administrator) a new link in /usr/lib:

sudo ln -s /usr/lib/libGL.so.1.2 /usr/lib/libGL.so

If you have a 64-bit Linux, use /usr/lib64 instead.

First check that you actually have "libGL.so.1.2" in /usr/lib or /usr/lib64; it might be called "libGL.so.1" or something else instead, or located in another directory, depending on the video drivers. You can use

locate libGL

to find the correct file to link to.

而我使用的是ubuntu 12.04 bit-64位，在/usr/lib/並沒有libGL.so檔案。

可以使用locate libGL尋找此檔案。結果：

找出了這麼多，當然是選擇64位平台下的libGL了。

但是針對這幾個，不知道要選擇哪一個好，還請高手指點。

Failed to load libGL.so

error libGL.so: wrong ELF class: ELFCLASS64

linux系統是64位的，這個命令不支援64位

最佳解決方案，把oralce-lib環境變數設定為lib32即可

最後選擇ln還36位

代碼：hudan@ubuntu:~/android/source/android4.1.1/out$ sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1.2 /usr/lib/libGL.so

再運行編譯好的system.img，出現如下的錯誤：

直接參數-ramdisk ramdisk.img去掉，結果模擬器跑起來了，但不能把核心啟動起來。

no ABI error , when creating an Android virtual device

E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

解決：sudo rm /var/lib/apt/lists/lock

上次make或或者mmm的時候產生一些錯誤的東西

可以使用：make clean 再重新make

解決：rm out/target/common/obj/APPS/ -r （如果還是有這樣的錯誤，就只能clean了）

四、運行編譯好的系統vi /etc/profile增加以下三句最終回合組態，給大家截個圖：只需要這三句就OK配置完，source /etc/profile 要是出現黑屏，建議重啟一下。接下：運行時只要：emulator完美運行：

下面是遇到的問題，可以看看：編譯完系統後，用模擬器運行系統，在2.3之前只需要配置：export ANDROID_PRODUCT_OUT=/home/hudan/android/source/android4.1.1/out/target/product/generic_x86export PATH=$PATH:/home/hudan/android/source/android4.1.1/out/host/linux-x86/bin但這樣配置就一直出現如下的錯誤：emulator: ERROR: You did not specify a virtual device name, and the systemdirectory could not be found.If you are an Android SDK user, please use '@<name>' or '-avd <name>'to start a given virtual device (see -help-avd for details).Otherwise, follow the instructions in -help-disk-images to start the emulator這就是adnroid4.1.1下emulator不能直接啟動並執行問題 參考：http://blog.csdn.net/dongminghao888/article/details/7860884最後配置export ANDROID_BUILD_TOP=/home/hudan/android/source/android4.1.1一切就都OK了。如果是研究android源碼的歡迎加群交流：android系統進階交流群：247039470轉載請附原文地址：http://blog.csdn.net/hudan2714/article/details/7926924
