h1. Nexus S (I902x) Build
This explains how to build Replicant for the Nexus S (I902x).
h2. Prerequisites
Before building, you must make sure that:
* You have installed the [[BuildDependencies]]
* You have downloaded Replicant 2.3, 4.0 or 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_crespo-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/@
