OSX Android Compilation Environment

1 Installing Xcode

Macport

Note: To determine/opt/local/bin before/usr/bin, if not, execute the following command, or modify the. bash_profile

Export Path=/opt/local/bin: $PATH

2 Install MAKE,GIT,GPG via Macport, if installed locally, or the version is newer, no installation required

sudo port install gmake libsdl git-core GnuPG

3 About make 3.82 version

Make 3.82 version has a bug, need to return 3.81, confirm the version with the following command

This program built for i386-apple-darwin11.0

Because my machine is already 3.81 version, so no operation this process, specifically can check the Android website

4 Modifying file descriptor limits

Add the following in ~/.bash_profile

# Set the number of open files to be 1024

Ulimit-s-N 1024

Two. Download the source code

1. Create a directory ~/bin

mkdir ~/bin

Add the following command to ~/.bash_profile

Export Path=~/bin: $PATH

2. Install repo, there is no use to install official website documentation, specific reasons you know

$ Curl https://git-repo.googlecode.com/files/repo-1.19 > ~/bin/repo

Then modify repo to execute permissions

chmod a+x ~/bin/repo

3. In order to facilitate the download, modify the repo file as follows

#REPO_URL = ' Http://gerrit.googlesource.com/git-repo '

Repo_url= ' http://code.google.com/p/git-repo/'

4. Create a source directory mkdir android-source ready to download

CD Android-source

5. Execute repo init, git library and official website is not the same, reason does not explain

Download source from Master

Repo Init-u Git://android.git.linaro.org/platform/manifest.git

or branch to download

Repo init-u git://android.git.linaro.org/platform/manifest.git-b "Branch Tag"

I chose a new android-4.4.2_r1.

Repo Init-u git://android.git.linaro.org/platform/manifest.git-b ANDROID-4.4.2_R1

You can view the source code corresponding to the tag that you want to download on the website.

After execution, there will be a directory locally. Repo

Then execute the repo sync download code in the Android-source directory

Download the code takes a long time, if you feel useless to continue to download, you can kill Ctrl + C, continue to perform repo sync until the download is complete.

Download completed, Android-source under a total of 27g,.repo 17G, source 10G about

Three. code can be compiled

Copy the code from the Android-source directory to the previously created partition/volumes/android, and under this partition you can delete the. Repo directory, which is useless and takes up a lot of space when compiling the code.

1. Initializing the compilation environment

SOURCE build/envsetup.sh

2. Select the compilation target, check the official website

Lunch Full-eng

3. Compiling the Code

Make

Or

Make-j4
