~~Title: Installing EFL on Ubuntu ~~
---

# Installing EFL on Ubuntu #
[The *Enlightenment Foundation Libraries (EFL)*](/about-efl.md) power millions of systems from mobile phones to set-top boxes, desktops, laptops, game systems and more. You'll need EFL if you want to develop apps for Enlightenment and for any of the devices that use Enlightenment for its visual interface. 

This tutorial describes several ways to install EFL on your system. You will only need to use one of these. Select your chosen method using the index on the right.

Many distributions offer EFL as an installable package from their default repositories. In this case you only need to use your distribution's software management system to install. However most versions of EFL in default repositories are out of date and will not compile more recent Enlightenment applications. If this is not an issue for you, read through the ["From  Distribution Repositories"](#From_Distribution_Repositories) section below.

Distributions often provide a special repository maintained by users or a method of integrating a bleeding edge version of EFL with your software management system. This means that once installed you can keep EFL current just by running system updates. If your distribution offers this, take a look at the section ["Installing from a Special Repository"](#Installing_from_a_Special_Repository).

The Enlightenment developers provide a pre-packaged source of EFL. Although not bleeding edge it is up to date and considered stable for production environments. You can download, compile and install it yourself by following the instructions in ["Installing from Packaged Source"](#Installing_from_Packaged_Source).

You can also download the source code for the most recent version from the EFL git repositories. To get started, read the section ["Installing from Git"](#Installing_from_Git).

Whichever installation method you use, visit ["Compiling EFL Applications"](#Compiling_EFL_Applications) to discover how to compile your Enlightenment applications.

## From  Distribution repos ##

EFL is not available in Ubuntu's official repositories, but you can install all the items you need from a special PPA repository. [See below for instructions on how to do that](#Installing_from_a_Special_Repository).

## Installing from a Special Repository ##

To install the latest EFL available from a special Ubuntu PPA repository, add the new repository with:

```bash
sudo add-apt-repository ppa:niko2040/e19
```
Refresh your repositories:

```bash
sudo apt-get update
```

And then install EFL and its development libraries:

```bash
sudo apt-get install libefl-dev
```

Ubuntu does not install by default the *gcc* compiler or *meson* or *ninja*, so, before you can [compile any apps](#Compiling_EFL_Applications), you will need to install those too:

```bash
sudo apt-get install gcc meson ninja-build
```

Also note that, due to EFL's fast development rate, it is unlikely the PPA will provide by default the latest version of EFL. This means that many of the examples in this documentation will probably need tweaking to work. If you would like to install an up to date version of EFL, see the [Installing from Source](#Installing_from_Source) section below or the instructions for [Installing from Git](#Installing_from_Git), also available below.

## Installing from Packaged Source ##

There are two versions available from the Enlightenment website. One is a packaged and available from the [EFL's download site](https://download.enlightenment.org/rel/libs/efl/). The other is the nightly bleeding edge version which you can [download using git](#Installing_from_Git). This section deals with installing with the packaged version available from the [EFL's download site](https://download.enlightenment.org/rel/libs/efl/).

### Step 1: Downloading Stable Version ###

[Download the latest version of EFL](https://download.enlightenment.org/rel/libs/efl/) and check it against its SHA256 hash:

```bash
wget https://download.enlightenment.org/rel/libs/efl/efl-X.XX.X.tar.xz
wget https://download.enlightenment.org/rel/libs/efl/efl-X.XX.X.tar.xz.sha256
cat efl-X.XX.X.tar.xz.sha256; sha256sum efl-X.XX.X.tar.xz
```

Note that you will have to change ``X.XX.X`` for the actual version of EFL.

### Step 2: Unpacking ###

Once you have the archive file containing EFL in your hard disk, unpack it with:

```bash
tar xvf efl-X.XX.X.tar.xz
```

This will produce a folder called ``efl-X.XX.X``.

### Step 3: Installing Dependencies ###

Before you can compile and install EFL, you will have to install some software packages EFL needs:

```bash
sudo apt install  check libssl-dev libsystemd-dev libjpeg-dev libglib2.0-dev libgstreamer1.0-dev libluajit-5.1-dev libfreetype6-dev libfontconfig1-dev libfribidi-dev libavahi-client-dev libharfbuzz-dev libibus-1.0-dev libx11-dev libxext-dev libxrender-dev libgl1-mesa-dev libopenjp2-7-dev libwebp-dev libgif-dev libtiff5-dev libpoppler-dev libpoppler-cpp-dev libspectre-dev libraw-dev librsvg2-dev libudev-dev libmount-dev libdbus-1-dev libpulse-dev libsndfile1-dev libxcursor-dev libxcomposite-dev libxinerama-dev libxrandr-dev libxtst-dev libxss-dev libbullet-dev libgstreamer-plugins-base1.0-dev doxygen libscim-dev libcurl4-openssl-dev
```

### Step 4: Building and Installing ###

Once you have installed all the packages EFL needs, ``cd`` into the ``efl-X.XX.X`` folder and run 

```bash
meson build
ninja -C build
sudo ninja -C build install
```

This will configure the files needed for compiling, actually compile the software, and then install it.

### Step 5: Carrying out Post Installation Tasks ###

As you are not installing to ``/usr`` but to ``/usr/local``, you will have to ensure that some files are visible to *dbus*:

```bash
sudo ln -s /usr/local/share/dbus-1/services/org.enlightenment.Ethumb.service /usr/share/dbus-1/services/org.enlightenment.Ethumb.service
```

You may also need to refresh your library path to make sure your apps can find the EFL libraries:

```bash
sudo ldconfig
```

## Installing from Git ##

You can also get the bleeding edge version of EFL by cloning it from the git repository.

### Step 1: Installing git and Cloning ###

By default, *git* is not installed in Ubuntu, so the first step is to install it:

```bash
sudo apt install git 
```

Next clone EFL's source code:

```bash
git clone https://git.enlightenment.org/core/efl.git
```

This will create a directory called ``efl/``.

### Step 2: Installing Dependencies ###

You will need to install some tools to build EFL:

```bash
sudo apt install gcc meson ninja-build
```

As well as the dependencies specific for EFL:

```bash
sudo apt install  check libssl-dev libsystemd-dev libjpeg-dev libglib2.0-dev libgstreamer1.0-dev libluajit-5.1-dev libfreetype6-dev libfontconfig1-dev libfribidi-dev libavahi-client-dev libharfbuzz-dev libibus-1.0-dev libx11-dev libxext-dev libxrender-dev libgl1-mesa-dev libgif-dev libtiff5-dev libpoppler-dev libpoppler-cpp-dev libspectre-dev libraw-dev librsvg2-dev libudev-dev libmount-dev libdbus-1-dev libpulse-dev libsndfile1-dev libxcursor-dev libxcomposite-dev libxinerama-dev libxrandr-dev libxtst-dev libxss-dev libgstreamer-plugins-base1.0-dev doxygen
```

### Step 3: Configuring the Software ###

Now you can ``cd`` into the ``efl`` directory and run the ``meson build`` script to create and configure the software ready for compilation:

```bash
meson build
```

Once configured, you can compile the software with:

```bash
ninja -C build
sudo ninja -C build install
```

### Step 4: Carrying out Post Installation Tasks ###

As you are not installing to ``/usr`` but to ``/usr/local``, you will have to ensure that some files are visible to *dbus*:

```bash
sudo ln -s /usr/local/share/dbus-1/services/org.enlightenment.Ethumb.service /usr/share/dbus-1/services/org.enlightenment.Ethumb.service
```

You may also need to refresh your library path to make sure your apps can find the EFL libraries:

```bash
sudo ldconfig
```

## Troubleshooting ##

If you are having problems compiling and installing EFL, you can come and seek advice on [any of our IRC channels](https://www.enlightenment.org/contact) or [post a ticket to our Phabricator](https://phab.enlightenment.org).

## Installing on Other Operating Systems ##

If you would like to install EFL on a different operating system visit the [Installing EFL](start) page.
