h1. Replicant source code

h2. Browsing the source code

The Replicant source code is currently hosted by the "FSF":https://www.fsf.org/ at: "git.replicant.us":https://git.replicant.us/replicant

There is one branch per Replicant version, such as @replicant-2.2@.

h2. Disk space

Before downloading the Replicant source code, make sure there is a considerable amount of disk space left on the drive you intent to build Replicant on.
It is advised to have 40-50GiB available for the Replicant source code and the produced files.

h2. Source tree root folder

The path to the source tree root folder *must not contain spaces*.

h2. Installing the repo tool

To be able download the complete source code, the "@repo@ tool":https://android.googlesource.com/tools/repo needs to be installed. The distribution you are using may already have the tool packaged and it may already been installed as part of the [[BuildDependenciesInstallation|Build dependencies installation]].

If the @repo@ tool is not available on your system, you can download and install it locally:

<pre>
mkdir tools
cd tools
wget https://commondatastorage.googleapis.com/git-repo-downloads/repo
chmod a+x repo
cd ../
</pre>

In the following, the local installation in @../tools/repo@ is assumed. If you have installed @repo@ from your system's package manager, replace

<pre>
../tools/repo
</pre>

with just

<pre>
repo
</pre>

at the beginning of the following commands.

h2. Initializing the repository

The source manifest is the list of all the git repositories that are present in the Replicant tree.
Each Replicant version has a dedicated branch with the proper source manifest.

In case errors such as *server certificate verification failed* happen, installing the CACert certificate may help:
<pre>
mkdir /usr/local/share/ca-certificates/cacert.org
wget -P /usr/local/share/ca-certificates/cacert.org http://www.cacert.org/certs/root.crt http://www.cacert.org/certs/class3.crt
update-ca-certificates
</pre>

h3. Replicant 6.0 release version

<pre>
mkdir replicant-6.0
cd replicant-6.0
../tools/repo init -u https://git.replicant.us/replicant/manifest.git -b replicant-6.0
</pre>

h3. Replicant 6.0 development version

<pre>
mkdir replicant-6.0-dev
cd replicant-6.0-dev
../tools/repo init -u https://git.replicant.us/replicant/manifest.git -b replicant-6.0-dev
</pre>

h3. Replicant 4.2

<pre>
mkdir replicant-4.2
cd replicant-4.2
../tools/repo init -u https://git.replicant.us/replicant/manifest.git -b replicant-4.2
</pre>

h3. Replicant 4.0

<pre>
mkdir replicant-4.0
cd replicant-4.0
../tools/repo init -u https://git.replicant.us/replicant/manifest.git -b replicant-4.0
</pre>

h3. Replicant 2.3

<pre>
mkdir replicant-2.3
cd replicant-2.3
../tools/repo init -u https://git.replicant.us/replicant/manifest.git -b replicant-2.3
</pre>

h3. Replicant 2.2

<pre>
mkdir replicant-2.2
cd replicant-2.2
../tools/repo init -u https://git.replicant.us/replicant/manifest.git -b replicant-2.2
</pre>

h2. Downloading/Updating the source code

Now that you have configured @repo@, you can start downloading Replicant sources for the desired version.

*This step is very long and can take hours to complete!*

<pre>
../tools/repo sync
</pre>

Once the source code is ready, you need to get the prebuilt applications (they are downloaded from F-Droid). The prebuilt applications are checked if they were signed with the "F-Droid signing key":https://f-droid.org/wiki/page/Release_Channels_and_Signing_Keys. The signing key can be retrieved and added to your GPG keyring using:

<pre>
gpg --recv-key 7A029E54DD5DCE7A
</pre>

Then you can download the prebuilts:

<pre>
vendor/replicant/get-prebuilts
</pre>

You must redo these steps each time you want to sync your tree, in order to keep it up to date. Future syncs are faster than the first one.
