Building
|
|
########
|
|
|
|
The following instructions will help you build Looking Glass from source code.
|
|
Before attempting this, you should have a basic understanding of
|
|
how to use the shell.
|
|
|
|
.. _download_source:
|
|
|
|
Downloading
|
|
-----------
|
|
|
|
Visit the Looking Glass `Download Page <https://looking-glass.io/downloads>`__,
|
|
and download the stable version (**recommended**).
|
|
You can also download a *bleeding-edge version*, or the latest RC version
|
|
during a Release Candidate cycle.
|
|
|
|
Developers can clone the source code repo with ``git``.
|
|
|
|
.. code:: bash
|
|
|
|
git clone --recursive https://github.com/gnif/LookingGlass.git
|
|
|
|
.. warning::
|
|
|
|
Please only clone from Git if you're a developer, and know what you're
|
|
doing. Looking Glass requires git submodules that must be setup and updated
|
|
when building. Source code downloads from the website come bundled with the
|
|
necessary submodules.
|
|
|
|
.. note::
|
|
|
|
When using the latest bleeding-edge client version,
|
|
you *MUST* download and install the corresponding host application.

|
|
|
|
These required libraries and tools should be installed first.
|

|
|
The below list of dependencies is for Debian. A community maintained list of
|
|
dependencies for other distributions for the current **stable** version of
|
|
Looking Glass is maintained on the wiki at:

Required dependencies
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|

Editor note: Listed dependencies are Debian packages containing the
|
|
required resources. All dependencies must be explicitly defined.
|
|
Omitting required dependencies that happen to be pulled in via
|
|
Depends: or Recommends: from another listed package is not allowed.
|
|
All required packages must be listed.

|
|
feature is disabled when running :ref:`cmake <client_building>`.

|
|
|
Fetching with APT
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
You can fetch these dependencies with the following command:
|
|
|
|
.. code:: bash
|
|
|
|
apt-get install binutils-dev cmake fonts-dejavu-core libfontconfig-dev \
|
|
gcc g++ pkg-config libegl-dev libgl-dev libgles-dev libspice-protocol-dev \

|
|
libpipewire-0.3-dev libpulse-dev libsamplerate0-dev
|
|
|
|
You may omit some dependencies if you disable the feature which requires them
|
|
when running :ref:`cmake <client_building>`.
|
|
(See :ref:`client_deps_may_be_disabled`)
|
|
|
|
.. _client_building:
|
|
|
|
Building
|
|
~~~~~~~~
|
|
|
|
If you've downloaded the source code as a zip file, simply unzip and ``cd``
|
|
into the new directory. If you've cloned the repo with ``git``, then ``cd``
|
|
into the *LookingGlass* directory.
|
|
|
|
.. code:: bash
|
|
|
|
mkdir client/build
|
|
cd client/build
|
|
cmake ../
|
|
make
|
|
|
|
This will build the ``looking-glass-client`` binary, which is used to display
|
|
frames from the guest.
|
|
|
|
You can then :ref:`continue installing Looking Glass <client_install>`, or run
|
|
it directly from the build directory:
|
|
|
|
.. code:: bash
|
|
|
|
./looking-glass-client
|
|
|
|
.. seealso::
|
|
|
|
- :ref:`Client installation <client_install>`
|
|
- :ref:`Client usage <client_usage>`
|
|
|
|
.. note::
|
|
|
|
For users running GNOME on Wayland, you may want to enable ``libdecor`` when
|
|
building.
|
|
|
|
.. code:: bash
|
|
|
|
cmake -DENABLE_LIBDECOR=ON ../
|
|
|
|
For details, see :ref:`the FAQ <gnome_wayland_decorations>`.
|
|
|
|
.. note::
|
|
|
|
The most common compile error is related to backtrace support. Try disabling
|
|
this when building:
|
|
|
|
.. code:: bash
|
|
|
|
cmake -DENABLE_BACKTRACE=0 ../
|
|
|
|
If you disable this and need support for a crash, use ``gdb`` to obtain a
|
|
backtrace manually.
|
|
|
|
.. _host_building:
|
|
|
|
Host
|
|
----
|
|
|
|
These instructions help you build the host yourself from the
|
|
:ref:`downloaded source code <download_source>`.
|
|
|
|
.. warning::
|
|
:name: dont-build-the-host
|
|
|
|
Building the host from source code is not recommended for most purposes,
|
|
and should only be attempted by users who are prepared to handle issues
|
|
on their own. Please download the pre-built binary installers from
|
|
https://looking-glass.io/downloads for stability, and increased support.
|
|
|
|
.. note::
|
|
|
|
The pre-built binaries also include NvFBC support built in, which is
|
|
only available to current Nvidia SDK license holders, and cannot
|
|
be enabled when building the host without also having a license.
|
|
|
|
