Replicant

h1. Galaxy S (I9000) Build

This explains how to build Replicant for the Galaxy S (I9000).

h2. Prerequisites

Before building, you must make sure that:

* You have installed the [[BuildDependencies]]

* You have downloaded Replicant 4.2 sources: [[ReplicantSources]]

* Your sources are up to date: [[ReplicantSources#DownloadingUpdating-the-source-from-the-repos|Downloading/Updating the source from the repos]]

* Your terminal is running in the directory where the sources were downloaded

h2. Warning

*Do not build as root, always build as user.*

h2. Building

Setup the build environment: 

<pre>

source build/envsetup.sh

lunch replicant_galaxysmtd-userdebug

export ANDROID_JAVA_HOME=$JAVA_HOME

</pre>

Start the build:

<pre>

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

make -j$parallel_tasks bacon

</pre>

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@.

h2. Output files

The produced files are located at:

* built target images: @out/target/product/crespo/@

* built host tools: @out/host/linux-x86/bin/@
