cp prebuilts/build-tools/linux-x86/bin/ninja out/host/linux-x86/bin/

ln -sf out/combined-***.ninja  build.ninja

 

ninja services // 单独编译services模块，参数一般是so库的名字(比如：libsurfaceflinger， which can find from android.bp in the SF module)

 

编译kernel：

ninja bootimage

 

编译services  生成目录为oat  

lunch后执行如下命令

export WITH_DEXPREOPT=false

make services

 

如果执行ninja进行快速编译时，遇到如下错误：

ninja: error while loading shared libraries: libjemalloc.so: cannot open shared object file: No such file or directory

使用如下解决方法：

sudo cp prebuilts/build-tools/linux-x86/lib64/libjemalloc.so /usr/lib
