Android Training Course (85) upgraded to version 4.0

ICS has finally been released and upgraded from 2.3.7 to 4.0.3. The upgrade command is as follows:

$ mkdir ~/bin$ PATH=~/bin:$PATH

Create the bin directory to store the downloaded software repo.

• $ Mkdir working directory $ CD working directory

Create a working directory to save the download source code.

$ repo init -u https://android.googlesource.com/platform/manifest

This line gets the code in the main branch. If your system is Ubuntu 11.10, you need to use the main distribution code for compilation. If it is a previous Android version, it will not be compiled.

$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1

This line uses the branch method. For example, you can add a branch to download the code of a specific version.

$ repo sync

This line is actually downloaded from the code.

The download code is between 5 GB and 6 GB, so it takes a long time. I downloaded it for one night. To speed up, you can also use the repo sync-j10 parameter.

After compilation, the occupied space is about 2 GB.

Use the following command line for compilation:

rm -rf out/

source build/envsetup.sh

lunch full-eng

make

To speed up compilation, you can also use the make-J8 method. In this way, 8 threads are used for compilation, but sometimes errors may occur because the threads are not synchronized, you can enter it several more times.

During compilation, a bug is found as follows:

To solve this problem, modify the file as follows:

Add "# include <stddef. h>" to the header of the linker. cpp file.

This completes compilation.
