Galaxy Nexus (I9250) Build¶
This page explains how to build Replicant for the Galaxy Nexus (I9250).
Prerequisites¶Before building, you must make sure that:
- You have installed the build dependencies: BuildDependenciesInstallation
- You have downloaded Replicant 6.0 sources: ReplicantSourceCode
- Your sources are up to date: Downloading/Updating the source from the repos
- Your terminal is running in the directory where the sources were downloaded
Do not build as root, always build as user.
See the build tips if you are facing issues.
All of the following build commands need to be run in the source tree root folder.
First, the toolchain needs to be built:
If you have executed any of the commands below and you want to run the toolchain build again, you will need to open a new shell.
Then, prepare the shell environment for the Replicant build:
. build/envsetup.sh lunch replicant_maguro-userdebug
Now you can start the build:
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) make -j$parallel_tasks bacon
-jn argument indicates the number of parallel tasks during the build. You can remove it from the command line to have only one task at a time.
$parallel_tasks holds an optimized number of parallel tasks for your hardware. You may want to reduce this number if e.g. the computer runs out of RAM during the build.
Finally, sign the resulting images:
The first time you run the script, it will ask you a few questions that are needed to generate the necessary signing keys.
Output files¶The produced files are located at:
- built target images:
- built host tools:
