Building Firefox On macOS
|
|
=========================
|
|
|
|
This document will help you get set up to build Firefox on your own
|
|
computer. Getting set up can take a while - we need to download a
|
|
lot of bytes! Even on a fast connection, this can take ten to fifteen
|
|
minutes of work, spread out over an hour or two.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
- **Memory:** 4GB RAM minimum, 8GB+ recommended.
|
|
- **Disk Space:** At least 30GB of free disk space.
|
|
- **Operating System:** macOS - most recent or prior release. It is advisable
|
|
to upgrade to the latest “point” release. See :ref:`build_hosts` for more
|
|
information.
|
|
|
|
|
|
1. System preparation
|
|
---------------------
|
|
|
|
1.1. Install Brew
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
Mozilla's source tree requires a number of third-party tools.
|
|
You will need to install `Homebrew <https://brew.sh/>`__ so that we
|
|
can automatically fetch the tools we need.
|
|
|
|
1.2. Install Xcode
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
Install Xcode from the App Store.
|
|
Once done, finalize the installation in your terminal:
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo xcode-select --switch /Applications/Xcode.app
|
|
sudo xcodebuild -license
|
|
|
|
1.3 Install Mercurial
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Mozilla's source code is hosted in Mercurial repositories. You will
|
|
need Mercurial to download and update the code. Additionally, we'll
|
|
put user-wide python package installations on the ``$PATH``, so that
|
|
both ``hg`` and ``moz-phab`` will be easily accessible:
|
|
|
|
.. code-block:: shell
|
|
|
|
echo "export PATH=\"$(python3 -m site --user-base)/bin:$PATH\"" >> ~/.zshenv
|
|
python3 -m pip install --user mercurial
|
|
|
|
Now, restart your shell so that the ``PATH`` change took effect.
|
|
You can test that Mercurial is installed by running:
|
|
|
|
.. code-block:: shell
|
|
|
|
hg version
|
|
|
|
.. note::
|
|
|
|
If you're using a shell other than ``zsh``, you'll need to manually add Python's
|
|
``bin`` directory to your ``PATH``, as your shell probably won't pick up our
|
|
changes in ``~/.zshenv``.
|
|
|
|
2. Bootstrap a copy of the Firefox source code
|
|
----------------------------------------------
|
|
|
|
Now that your system is ready, we can download the source code and have Firefox
|
|
automatically download the other dependencies it needs. The below command
|
|
will download a lot of data (years of Firefox history!) then guide you through
|
|
the interactive setup process.
|
|
|
|
.. code-block:: shell
|
|
|
|
curl https://hg.mozilla.org/mozilla-central/raw-file/default/python/mozboot/bin/bootstrap.py -O
|
|
python3 bootstrap.py
|
|
|
|
.. note::
|
|
|
|
In general, the Firefox workflow works best with Mercurial. However,
|
|
if you'd prefer to use ``git``, you can grab the source code in
|
|
"git" form by running the bootstrap script with the ``vcs`` parameter:
|
|
|
|
.. code-block:: shell
|
|
|
|
python3 bootstrap.py --vcs=git
|
|
|
|
This uses `Git Cinnabar <https://github.com/glandium/git-cinnabar/>`_ under the hood.
|
|
|
|
Choosing a build type
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
If you aren't modifying the Firefox backend, then then select one of the
|
|
:ref:`Artifact Mode <Understanding Artifact Builds>` options. If you are
|
|
building Firefox for Android, you should also see the :ref:`GeckoView Contributor Guide`.
|
|
|
|
3. Build
|
|
--------
|
|
|
|
Now that your system is bootstrapped, you should be able to build!
|
|
|
|
.. code-block:: shell
|
|
|
|
rm bootstrap.py
|
|
cd mozilla-unified
|
|
./mach build
|
|
./mach run
|
|
|
|
🎉 Congratulations! You've built your own home-grown Firefox!
|
|
|
|
Now the fun starts
|
|
------------------
|
|
|
|
Time to start hacking! You should join us on `Matrix <https://chat.mozilla.org/>`_,
|
|
say hello in the `Introduction channel
|
|
<https://chat.mozilla.org/#/room/#introduction:mozilla.org>`_, and `find a bug to
|
|
start working on <https://codetribute.mozilla.org/>`_.
|
|
See the :ref:`Firefox Contributors' Quick Reference` to learn how to test your changes,
|
|
send patches to Mozilla, update your source code locally, and more.
|
|
|
|
Troubleshooting
|
|
---------------
|
|
|
|
macOS SDK is unsupported
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. only:: comment
|
|
|
|
If you are editing this section to bump the SDK and Xcode version, I'd recommend
|
|
following the steps to ensure that they're not obsolete. Apple doesn't guarantee
|
|
the structure of Xcode, so the SDK could be moved to a different location or
|
|
stored differently.
|
|
|
|
If the SDK included with your Xcode installation is not supported by Firefox,
|
|
you'll need to manually install one that is compatible.
|
|
We're currently using the 10.12 SDK on our build servers, so that's the one that you
|
|
should install:
|
|
|
|
1. Go to the `More Downloads for Apple Developers <https://developer.apple.com/download/more/>`_ page
|
|
and download Xcode 8.2.
|
|
2. Once downloaded, extract ``Xcode_8.2.xip``.
|
|
3. In your terminal, copy the SDK from the installer:
|
|
|
|
.. code-block:: shell
|
|
|
|
mkdir -p ~/.mozbuild/macos-sdk
|
|
# This assumes that Xcode is in your "Downloads" folder
|
|
cp -aH ~/Downloads/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk ~/.mozbuild/macos-sdk/
|
|
|
|
4. Finally, inform the Firefox build about this SDK by creating (or editing) a file called ``mozconfig`` file
|
|
in the Firefox source code directory. Add the following line:
|
|
|
|
.. code-block::
|
|
|
|
ac_add_options --with-macos-sdk=$HOME/.mozbuild/macos-sdk/MacOSX10.12.sdk
|
|
|
|
5. Now, you should be able to successfully run ``./mach build``.
