This page explains how to build Replicant for the Galaxy S 3 (I9300).

h2. Prerequisites

7 2 Paul Kocialkowski
Before building, you must make sure that:
8 4 Paul Kocialkowski
* You have installed the build dependencies: [[BuildDependenciesInstallation]]
9 7 Wolfgang Wiedmeyer
* You have downloaded Replicant 6.0 sources: [[ReplicantSourceCode]]
10 6 Wolfgang Wiedmeyer
* Your sources are up to date: [[ReplicantSourceCode#DownloadingUpdating-the-source-code|Downloading/Updating the source from the repos]]
11 2 Paul Kocialkowski
* Your terminal is running in the directory where the sources were downloaded

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

First, the toolchain needs to be built for replicant 6:
24 1 Paul Kocialkowski
<pre>
25 6 Wolfgang Wiedmeyer
./vendor/replicant/build-toolchain
26
</pre>
27
28
*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.*
29
30
Then, prepare the shell environment for the Replicant build:
31
32
<pre>
33
. build/envsetup.sh
34 2 Paul Kocialkowski
lunch replicant_i9300-userdebug
35 1 Paul Kocialkowski
</pre>
36
37 9 Wolfgang Wiedmeyer
Now you can start the build:
38 6 Wolfgang Wiedmeyer
39 1 Paul Kocialkowski
<pre>
40 2 Paul Kocialkowski
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
41 1 Paul Kocialkowski
make -j$parallel_tasks bacon
42
</pre>
43
44 9 Wolfgang Wiedmeyer
The @-jn@ argument indicates the number of parallel tasks during the build. You can remove it from the command line to have only one task at a time.
45
@$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.
46 1 Paul Kocialkowski
47 6 Wolfgang Wiedmeyer
Finally, sign the resulting images:
48
49
<pre>
50
./vendor/replicant/sign-build i9300
51
</pre>
52
53 9 Wolfgang Wiedmeyer
The first time you run the script, it will ask you a few questions that are needed to generate the necessary signing keys.
