Before building, you must make sure:
8
* You have installed the [[BuildDependencies]]
9
* You have downloaded Replicant sources for the SDK version you want: [[GettingReplicantSources]]
10
* Your sources are up to date: [[GettingReplicantSources#DownloadingUpdating-the-source-from-the-repos|Downloading/Updating the source from the repos]]
11
* You are in the directory where the sources were downloaded
12

Setup the build environment: 
20 1 Denis 'GNUtoo' Carikli
<pre>
21
source build/envsetup.sh
22 8 Paul Kocialkowski
lunch sdk-eng
23 1 Denis 'GNUtoo' Carikli
export ANDROID_JAVA_HOME=$JAVA_HOME
24
</pre>
25 7 Paul Kocialkowski
26
Start the build:
27
<pre>
28
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
29
make -j$parallel_tasks sdk
30
</pre>
31
32
The -jn argument is to indicate the number of parallel tasks during the build. 
33
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@.
