h1. Galaxy S 2 (I9100) build

h2. Prerequisites

The following are required to build Replicant for the Galaxy S 2 (I9100):
* [[BuildDependenciesInstallation|Build dependencies installation]]
* [[Replicant60ReplicantSourceCode|Replicant 6.0 source code]]

h2. Build

*There is no need to build as root*, building as a regular user should be preferred.

All of the following build commands need to be run in the source tree root folder.

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_i9100-userdebug
</pre>

Now you can start the build:

<pre>
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
make -j$parallel_tasks bacon
</pre>

The @-jn@ argument indicates the number of parallel tasks during the build (you can remove it from the command line to have only one task at a time).
@$parallel_tasks@ holds an optimized number of parallel tasks for your hardware. You may want to reduce this number if e.g. the computer runs out of RAM during the build.

Finally, sign the resulting images:

<pre>
./vendor/replicant/sign-build i9100
</pre>

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

h2. Produced binaries

The produced binaries are located at:
* @out/dist/i9100/@ for the target
* @out/host/linux-x86/bin/@ for the host
