Before building, you must make sure:
8
* You have installed the [[BuildDependencies]]
9
* You have downloaded Replicant 4.0 sources: [[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

Setup the build environment: 
20
<pre>
21
source build/envsetup.sh
22
lunch replicant_i9300-eng
23
export ANDROID_JAVA_HOME=$JAVA_HOME
24
</pre>
25
26
Start the build:
27
<pre>
28
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
29
make -j$parallel_tasks bootimage
30
make -j$parallel_tasks systemimage
31
make -j$parallel_tasks userdataimage
32
</pre>
33
34
The -jn argument is to indicate the number of parallel tasks during the build. 
35
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@.
