Building the System(lollipop x86)

Building the System

The following instructions to build the LOLLIPOP-X86 SOURCE CODE. The basic sequence of build commands is as follows:

Set up environment

nitialize the environment with the envsetup.sh script. Note that replacing source with . (a single dot) saves a few characters, and the short form is more commonly used in documentation.

source build/envsetup.sh

or

. build/envsetup.sh

Choose a Target

Choose which target to build with lunch. The exact configuration can be passed as an argument. First you should run the following command:

lunch

Then you will see many targets. In our project, we usually choose "android_x86_64-x" targets to build. There are three kinds of build type:

BuildType	Use
user	limited access; suited for production
userdebug	like "user" but with root access and debuggability; preferred for debugging
eng	development configuration with additional debugging tools

For more information about building for and running on actual hardware, see Running Builds.

Build the code

Build everything with make. GNU make can handle parallel tasks with a -jN argument, and it's common to use a number of tasks N that's between 1 and 2 times the number of hardware threads on the computer being used for the build. For example, on a dual-E5520 machine (2 CPUs, 4 cores per CPU, 2 threads per core), the fastest builds are made with commands between make -j16 and make -j32.

And for openthos, we want to run our system oe PC. So you should build it into an image . You can add a "iso_img" to build a .iso image and it can boot into lengacy BIOS-compatibility mode:

make -jX iso_img

To boot into UEFI mode, you should build a efi_img instead:

make -jX efi_img

Waiting for the build complete and run your own image!
