ubuntu16.04下firefly rk3288的编译安卓4.4

一.背景

OS: ubuntu 16.04

二.配置交叉编译环境

2.1 安装openjdk

sudo apt-get install openjdk-7-jdk

2.2 使在同一台机器上可以编译android 5.1及以下的版本

sudo /var/lib/dpkg/info/openjdk-7-jdk:amd64.prerm remove

2.3 安装toolslib

sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev 
 libesd0-dev libwxgtk3.0-dev squashfs-tools build-essential zip curl 
 libncurses5-dev zlib1g-dev pngcrush schedtool libxml2 libxml2-utils 
 xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev 
 lib32readline-gplv2-dev gcc-multilib libswitch-perl 
 libssl1.0.0 libssl-dev

2.4 源码

git clone https://TeeFirefly@bitbucket.org/T-Firefly/firefly-rk3288.git

2.5 编译内核

cd firefly-rk3288

cd kernel

make firefly-rk3288_defconfig
make -j8 firefly-rk3288.img

2.6 编译 Android

make -j8 (默认编译出来的是userdebug版本)

2.6.1 此时出现以下错误:

build/core/main.mk:46: *  You are using version 4.1 of make.
build/core/main.mk:47: *  Android can only be built by versions 3.81 and 3.82.

2.6.2 解决方案:安装低版本make

wget ftp://ftp.gnu.org/gnu/make/make-3.82.tar.bz2

tar xvf make-3.82.tar.bz2

cd make-3.82

./configure

make

sudo make install

cd /usr/bin

sudo cp make make_back

sudo cp /usr/local/bin/make ./

继续make -j8

2.6.3出现以下错误:

You are attempting to build with an unsupported JDK.
 
You use OpenJDK but only Sun/Oracle JDK is supported.

2.6.4 解决方案:使用sun/oracle jdk

sudo apt-get update

sudo apt-get remove openjdk* (卸载openjdk)

sudo apt-get install oracle-java6-installer (无法安装)

那么直接下载http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-419409.html#jdk-6u21-oth-JPR

 chmod u+x jdk-6u45-linux-x64.bin

sudo ./jdk-6u45-linux-x64.bin (执行完就出现一目录,将其路径设置到PATH中,如/home/jellojdk/jdk1.6.0_45/bin,那么PATH=/home/jellojdk/jdk1.6.0_45/bin:$PATH)

update-alternatives --display java (当前sdk)

java - 手动模式
  link best version is /usr/lib/jvm/java-9-oracle/bin/java
 链接目前指向 /usr/lib/jvm/java-9-oracle/bin/java
  link java is /usr/bin/java
/usr/lib/jvm/java-9-oracle/bin/java - 优先级 1091

update-alternatives  --install  /usr/bin/java java /home/jello/jdk/jdk1.6.0_45/bin/java 1092(设置优先级为1092,比1091高)

重新打开一终端,输入java -version 输出如下信息:

jello@jello-Inspiron-N4050:~$ java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

source build/envsetup.sh

lunch rk3288-eng

继续make -j8

./mkimage.sh
