h1. SDK Build
This explains how to build Replicant SDK.
h2. Prerequisites
Before building, you must make sure:
* You have installed the [[BuildDependencies]]
* You have downloaded Replicant sources for the SDK version you want: [[GettingReplicantSources]]
* Your sources are up to date: [[GettingReplicantSources#DownloadingUpdating-the-source-from-the-repos|Downloading/Updating the source from the repos]]
* You are 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 sdk-eng
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 sdk
</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@.
