Galaxy S 3 4G (I9305) Build¶

This explains how to build Replicant for the Galaxy S 3 4G (I9305).

Prerequisites¶

• You have installed the build dependencies: BuildDependenciesInstallation
• You have downloaded Replicant 6.0 sources: Replicant60ReplicantSourceCode
• 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

Warning¶

Do not build as root, always build as user.

Building¶

Setup the build environment:

. build/envsetup.sh
lunch replicant_i9305-userdebug
export ANDROID_JAVA_HOME=$JAVA_HOME

Start the build:

parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
make -j$parallel_tasks bacon

The -jn argument is to indicate the number of parallel tasks during the build.
You can remove it from the command line to have only one task at a time. With fast hardware, best results will come with -j9, -j16 and -j32.

Finally, sign the resulting images:

./vendor/replicant/sign-build i9305

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¶

• built target images: out/dist/
• built host tools: out/host/linux-x86/bin/
