Ubuntu搭建imx6 android4.4.3编译环境及源码下载总结

一.code download $ sudo apt-get install uuid uuid-dev $ sudo apt-get install zlib1g-dev liblz-dev $ sudo apt-get install liblzo2-2 liblzo2-dev $ sudo add-apt-repository ppa:git-core/ppa $ sudo apt-get install lzop $ sudo apt-get update $ sudo apt-get install git-core curl $ sudo apt-get install u-boot-tools $sudo apt-get install flex bison gperf libesd0-dev libwxgtk2.8-dev zlib1g-dev build-essential libx11-dev libncurses5-dev genext2fs u-boot-tools $sudo apt-get install git git-core $sudo apt-get install libswitch-perl sudo apt-get  install libxml2-utils sudo apt-get install gcc-multilib sudo apt-get install g++ sudo apt-get install xsltproc # cd /opt (or any other directory where you placed the android_KK4.4.3_2.0.0- ga_core_source.tar.gz file) $ tar xzvf android_KK4.4.3_2.0.0-ga_core_source.tar.gz $ cd android_KK4.4.3_2.0.0-ga_core_source/code/ $ tar xzvf KK4.4.3_2.0.0-ga.tar.gz mkdir ~/bin PATH=~/bin/repo:$PATH curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo/repo mkdir myandroid cd myandroid repo init -u git://mirrors.ustc.edu.cn/aosp/platform/manifest ## 如果提示无法连接到 gerrit.googlesource.com，可以编辑 ~/bin/repo，把 REPO_URL 一行替换成下面的： ## REPO_URL = 'https://gerrit-googlesource.proxy.ustclug.org/git-repo' repo init -u git://mirrors.ustc.edu.cn/aosp/platform/manifest -b android-4.4.3_r1 运行脚本： #!/bin/sh repo sync -f -j4 while [ $? -ne 0 ]  do repo sync -f -j4 done  uboot下载： $ cd myandroid/bootable/bootloader     $ git clone git://git.freescale.com/imx/uboot-imx.git uboot-imx -b kk4.4.3_2.0.0-ga     $ cd uboot-imx     $ git checkout kk4.4.3_2.0.0-ga kernel下载： $ cd myandroid $ git clone git://git.freescale.com/imx/linux-2.6-imx.git kernel_imx -b kk4.4.3_2.0.0-ga $ cd kernel_imx $ git checkout kk4.4.3_2.0.0-ga 二.Patch code for i.MX 1. Assume you have unzipped the i.MX Android release package to  /opt/android_KK4.4.3_2.0.0-ga_source . $ cd ~/myandroid $ source /opt/android_KK4.4.3_2.0.0-ga_core_source/code/KK4.4.3_2.0.0-ga/and_patch.sh $ help 2. You should see that the "c_patch" function is available. $ c_patch /opt/android_KK4.4.3_2.0.0-ga_core_source/code/KK4.4.3_2.0.0-ga imx_KK4.4.3_2.0.0-ga Here, "/opt/android_KK4.4.3_2.0.0-ga_source/code/KK4.4.3_2.0.0-ga" is the location of the patches, which is the directory created when you unzip the release package. "imx_KK4.4.3_2.0.0-ga" is the branch which will be created automatically for you to hold all patches (only in those existing Google gits). 3. If everything is OK, "c_patch" will generate the following output to indicate the successful patch: ************************************************************** Success: Now you can build the Android code for FSL i.MX platform

**************************************************************

三.编译环境

下载JDK1.6，链接http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase6-419409.html

脚本如下：

#!/bin/shexport JAVA_HOME=/opt/jdk1.6.0_45export JAVA_BIN=/opt/jdk1.6.0_45/binexport PATH=$PATH:$JAVA_HOME/binexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jarexport JAVA_HOME JAVA_BIN PATH CLASSPATHsource build/envsetup.sh

lunch sabresd_6dq-user

楼主在64位上安装32，把那两个x86的都装了一遍，都错了，哈哈，最后下载文件：jdk-6u45-linux-x64.bin

#uname -a

很明显楼主是：64位操作系统；那么应该下载jdk-6u45-linux-x64.bin

 Linux x86：32位操作系统；

 Linux x64：64位操作系统；

四.编译出现的疑难杂症

Android源码：科大镜像下载Android编译版本： PLATFORM_VERSION=4.4.3OS 操作系统平台：Linux wugn-Inspiron-3542 3.13.0-144-generic #193-Ubuntu SMP Thu Mar 15 17:03:53 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux（Ubuntu14.04  64bit）

1. 要用jdk1.6，不能用jdk1.7

2. /bin/bash: bison: command not found

方法：sudo apt-get install bison

3.  /bin/bash: xsltproc: command not found

方法：sudo apt-get install xsltproc

4./bin/bash: flex: command not foundmake: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] Error 127

方法：sudo apt-get install flex

5. sh: gperf: not foundcalling gperf failed: 32512 at ./makeprop.pl line 140.

方法：sudo apt-get install gperf

6. gcc: error trying to exec 'cc1plus': execvp: No such file or directory

方法：sudo apt-get install g++

7.collect2: error: ld terminated with signal 9

方法：增加ubuntu的虚拟内存。具体操作如下：

setp1：查看系统虚拟内存，命令：free -m

[html]  view plain  copy carson@carson-pc:~$ free -m               total       used       free     shared    buffers     cached  Mem:          1998       1528        469          0          6        423  -/+ buffers/cache:       1098        900  Swap:         2036        361       1675   我这是已经增加swap的，一般swap2G左右就足够编译android用的。在编译过程中，虽然增加了2G，但在编译时，若做一些操作比较占用swap的话，也会出现此问题。比如从移动硬盘copy android 源码。

setp2.创建一个 Swap 文件。

mkdir swapcd swap  sudo dd if=/dev/zero of=swapfile bs=1024 count=100000出现下列提示，上面命令中的 count 即代表swap文件大小，即增加的虚拟内存大小。此命令出现如下信息

[html]  view plain  copy 100000+0 records in  100000+0 records out  102400000 bytes (102 MB) copied, 0.377325 s, 271 MB/s   setp3：把生成的文件转换成 Swap 文件 sudo mkswap swapfile

此命令出现如下信息：

[html]  view plain  copy Setting up swapspace version 1, size = 99996 KiB  no label, UUID=b26fe88c-11c2-40ad-8139-6e69e96b6b68   setp4：激活 Swap 文件。 sudo swapon swapfile

此时free -m 查看Swap信息

[html]  view plain  copy total       used       free     shared    buffers     cached   1998     <span style="font-family:Arial, Helvetica, sans-serif;">  1189        809          0         34        624</span>   [html]  view plain  copy -/+ buffers/cache:        530       1468  Swap:         2134        986       1148   至此，swap已经增加成功了，如果想卸载刚增加的swap；

sudo swapoff swapfile

如果需要一直保持这个 swap ，可以sudo -s换到root然后把它写入 /etc/fstab 文件。 swapfilepath swap swap defaults 0 0

方法：sudo apt-get install libc6-dev:i386

     sudo apt-get install build-essential

     sudo apt-get install gcc-multilib

9./bin/sh: gcc: not found

方法：sudo apt-get install gcc，gcc是C的编译器

10.gccgcc: error trying to exec 'cc1plus': execvp: gcc: error trying to exec 'No such file or directory

方法：sudo apt-get install g++，g++是C++的编译器

11. /bin/bash: xmllint: command not found方法：sudo apt-get  install libxml2-utils

12.make[1]: lzma: Command not found

方法：sudo apt-get  install lzma未完待续
