编译步骤
1）切换到下载你的sprdroid源代码目录
$cd xxxxx #xxxx源代码所在地方
2）添加必要的环境变量
$source bulid/envsetup.sh #注意每次切换都需执行此命令，否则，可能导致出现编译找#不到规则等问题
3）选择编译系统版本
$lunch
4）安装kernel header给android编译
$kheader
5）编译
make -j4全编，容易出错，一般会只编译某部分
make bootimage -j4编译镜像
make bootloader -j4编译bootloader
6）在out/target/product/****/目录下出现boot.img、system.img、userdata.img等镜像
编译问题1
编译出现：MODULE.TARGET.APPS.TvQuickSettings already defined by packages/apps/TvSettings/QuickSettings
下载的源码有问题，定位指定的位置发现由于存在重复文件导致的，删除相关文件，得到解决！
编译问题2
Try increasing heap size with java option '-Xmx
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4g"
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server
编译问题3
jack-server服务器无法启动
FAILED: setup-jack-server
Jack server installation not found
No Jack server running. Try ‘jack-admin start-server’
No Jack server running. Try ‘jack-admin start-server’
Jack server failed to (re)start, try ‘jack-diagnose’ or see Jack server log
解决方法：
$ cd
$ sudo mount -o username=ubuntu,password=12cdCD //10.0.1.120/UBTSWCenter /mnt
$ sh /mnt/Ubuntu/1404Ubuntu/jack-server.sh
然后可以进行正常编译
编译问题4
vendor/sprd/proprietories-source/autotest/Android.mk: error: autotest (EXECUTABLES android-arm) missing libwpa_client (SHARED_LIBRARIES android-arm)
You can set ALLOW_MISSING_DEPENDENCIES=true in your environment if this is intentional, but that may defer real problems until later in the build.
vendor/sprd/proprietories-source/factorytest/Android.mk: error: factorytest (EXECUTABLES android-arm) missing libwpa_client (SHARED_LIBRARIES android-arm)
You can set ALLOW_MISSING_DEPENDENCIES=true in your environment if this is intentional, but that may defer real problems until later in the build.
解决方法：
rm vendor/sprd/proprietories-source/autotest/Android.mk vendor/sprd/proprietories-source/factorytest/Android.mk
最后附上Java8的安装
使用ppa/源方式安装java8
1.添加ppa
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
2.安装Oracle-java-installer
jdk7
sudo apt-get install oracle-java7-installer
jdk8
sudo apt-get install oracle-java8-installer
安装器会提示你同意 oracle 的服务条款,选择 ok
然后选择yes 即可
如果你懒,不想自己手动点击.也可以加入下面的这条命令,默认同意条款:
JDK7 默认选择条款
echo oracle-java7-installer shared/accepted-oracle-license-v1-1
select true
|
sudo /usr/bin/debconf-set-selections
JDK8 默认选择条款
echo oracle-java8-installer shared/accepted-oracle-license-v1-1
select true | sudo /usr/bin/debconf-set-selections
接下会是等待(依个人网速定)
如果你因为防火墙或者其他原因,导致installer 下载速度很慢,可以中断操作.然后下载好相应jdk的tar.gz 包,放在:
/var/cache/oracle-jdk7-installer (jdk7)
/var/cache/oracle-jdk8-installer (jdk8)
下面,然后安装一次installer. installer 则会默认使用 你下载的tar.gz包
3.设置系统默认jdk
JDk7
sudo update-java-alternatives -s java-7-oracle
JDK8
sudo update-java-alternatives -s java-8-oracle
如果即安装了jdk7,又安装了jdk8,要实现两者的切换,可以:
jdk8 切换到jdk7
sudo update-java-alternatives -s java-7-oracle
jdk7 切换到jdk8
sudo
update-java-alternatives -s java-8-oracle
4.测试jdk 是是否安装成功:
java -version
javac -version
Try increasing heap size with java option '-Xmx
