Build a distributed Android compiling environment

Because the android source code extracted by Google git is not configured for Distributed compilation, you need to use some tools to build a distributed compilation environment to speed up Android compilation. The following steps are performed on centos 5.2, for more information, see.

1) install the DistCC RPM package

Rpm-IVH distcc-2.18.3-2.el5.rf.i386.rpm

Rpm-IVH distcc-server-2.18.3-2.el5.rf.i386.rpm

2) enable the system to load the distccd service process by default at startup.

Shell-> setup-> System Service-> distccd select this option

Start the distccd Service

/Etc/rc. d/init. d/distccd start

3) copy the compiler to the specified system directory.

All machines involved in Distributed compilation must install the cross compiler under a specific directory,

Arm-linux-4.1.1->/usr/local # This compiler is required for Kernel Compilation

Prebuilt->/usr/local # This compiler is required for Android Compilation

4) modify the configuration file

VI/etc/sysconfig/distccd # Add the following lines

Options = "-nice10-jobs5-Allow 192.168.0.0/16"

User = "DistCC"

Mkdir/etc/DistCC/

VI/etc/DistCC/hosts # Add the host involved in Distributed compilation to the hosts list, such

Localhost/1 192.168.80.3/1 192.168.80.5/1...

5) Create the DistCC home directory

Mkdir-P/home/DistCC

Chown DistCC. DistCC/home/DistCC

6) start to compile the source code.

CD cupcake

. Build/envsetup. Sh

Tapas # configuration options will pop up for this command

Compile after configuration is complete.

Make-J20 #20 indicates that 20 threads are compiled simultaneously.
