Galaxy S Build¶

This explains how to build Replicant for the Galaxy S.

Prerequisites¶

Before building, you must make sure:

• You have installed the BuildDependencies
• You have downloaded Replicant 2.3 or 4.0 sources: GettingReplicantSources
• Your sources are up to date: Downloading/Updating the source from the repos
• You are in the directory where the sources were downloaded

Warning¶

Do not build as root, always build as user.

Building¶

Setup the build environment:

source build/envsetup.sh
lunch replicant_galaxysmtd-eng
export ANDROID_JAVA_HOME=$JAVA_HOME

Start the build:

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

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.

Output files¶

Find the produced files:

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