This page explains how to build Replicant for the Galaxy S 3 4G (I9305).

h2. Prerequisites

7
Before building, you must make sure that:
8
* You have installed the build dependencies: [[BuildDependenciesInstallation]]
9 2 Wolfgang Wiedmeyer
* You have downloaded Replicant 6.0 sources: [[ReplicantSourceCode]]
10
* Your sources are up to date: [[ReplicantSourceCode#DownloadingUpdating-the-source-code|Downloading/Updating the source from the repos]]
11 1 Wolfgang Wiedmeyer
* Your terminal is running in the directory where the sources were downloaded

19 3 Wolfgang Wiedmeyer
All of the following build commands need to be run in the source tree root folder.
20 1 Wolfgang Wiedmeyer
21 3 Wolfgang Wiedmeyer
First, the toolchain needs to be built:
22 1 Wolfgang Wiedmeyer
<pre>
23 3 Wolfgang Wiedmeyer
./vendor/replicant/build-toolchain
24
</pre>
25
26
*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.*
27
28
Then, prepare the shell environment for the Replicant build:
29
30
<pre>
31 1 Wolfgang Wiedmeyer
. build/envsetup.sh
32
lunch replicant_i9305-userdebug
33
</pre>
34
35 3 Wolfgang Wiedmeyer
Now you can start the build:
36 1 Wolfgang Wiedmeyer
37
<pre>
38
parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc)
39
make -j$parallel_tasks bacon
40
</pre>
41
42 3 Wolfgang Wiedmeyer
The @-jn@ argument indicates the number of parallel tasks during the build. You can remove it from the command line to have only one task at a time.
43
@$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.
44 1 Wolfgang Wiedmeyer
45
Finally, sign the resulting images:
46
47
<pre>
48
./vendor/replicant/sign-build i9305
49
</pre>
50
51 3 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.
