h1. Galaxy Note 2 (N7100) Build

This explains how to build Replicant for the Galaxy Note 2 (N7100).

h2. Prerequisites

Before building, you must make sure that:
* You have installed the build dependencies: [[BuildDependenciesInstallation]]
* You have downloaded Replicant 6.0 sources: [[Replicant60ReplicantSourceCode]]
* Your sources are up to date: [[Replicant60ReplicantSourceCode#DownloadingUpdating-the-source-code|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

First, the toolchain needs to be built:
<pre>
./vendor/replicant/build-toolchain
</pre>

*If you have executed any of the commands below and you want to run the toolchain build again, you will need to open a new shell.*

Then, prepare the shell environment for the Replicant build:

<pre>
. build/envsetup.sh
lunch replicant_n7100-userdebug
</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@.

Finally, sign the resulting images:

<pre>
./vendor/replicant/sign-build n7100
</pre>

The first time you run the script, it will ask you a few questions that are needed to generate the necessary signing keys.
