Android: Build Environment

Android > Build Environment

This article will guide you through setting up a Debian 7 64 bit box for building the Android 2.3 thorugh 4.4 OS sources. This was done on a basic headless fresh Debian install, your mileage may very with your particular setup.

Prerequisites

• Official Android how to set up a Build Environment
• 64 Bit Debian 7 (in a Virtual Machine works fine)
  • This was written for a fresh basic install, you may find some of this unnecessary, or incomplete with your system.
• How to download Android sources

Dependencies

Debian Packages

First step is to add multi-arch support, for the required i386 packages.

   # sudo dpkg --add-architecture i386
   # sudo apt-get update

Now to install the necessary packages (Due to system install variations, this may not be an exhaustive list).

   # sudo apt-get install git gnupg flex bison gperf build-essential \
   zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
   libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 \
   libgl1-mesa-dev g++-multilib mingw32 tofrodos \
   python-markdown libxml2-utils xsltproc zlib1g-dev:i386 gcc-4.4-multilib \
   g++-4.4-multilib

Java

For the FriendlyARM versions of Android, Java JDK 6 is required for the build. Go to Java Downloads and download make-jpkg jdk-6u45-linux-x64.bin you will need to log in, (bugmenot.com works well in these situations.) After downloading, you need to create a Debian package to install.

   # fakeroot make-jpkg jdk-6u45-linux-x64.bin
   # sudo dpkg -i oracle-j2sdk1.6\_1.6.0+update45\_amd64.deb

System Configuration

Java alternative set up

   # sudo ln -s /usr/lib/jvm/j2sdk1.6-oracle/  /usr/lib/jvm/java-6-sun
   # sudo update-java-alternatives -s java-6-oracle

libGL.so symlink

Check first if this is necessary, one box this was done on it was, the other it was not.

   # sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so

GCC alternative set up

   # sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.4

Now you'll need to extract your sources if you got a tarball, and or cd into the repo if you downloaded that way. You are now ready for compiling.
