{{Warning|Since this guide uses packages from Xenial and PPA's, this may cause instability to your system
{{Warning|2=Important|1=Building software is not a simple task.  If you simply wish to try out Plasma 5, I recommend you look at other methods
The aim of this guide is to help you build KDE Plasma 5 for development and/or use.  I decided to write a guide specifically for Ubuntu 14.04 because it can be tricky to resolve all of the build dependencies and problems specific to this system. 
Since you will be building out of the master branch, dependencies may change after this guide is written.  I will try to update this guide to cover any new dependencies.
Most of the instructions in this guide can be cut and pasted.  A few steps will require you to edit some files or interact with a GUI. 
{{Note|Following the instructions in this guide will install Qt to /opt/Qt5.7.0 and kde to /opt/kde-5
== Install a recent version of cmake ==
You will need to install a more recent version of cmake to build. 
sudo apt-get install build-essential
wget https://cmake.org/files/v3.6/cmake-3.6.1.tar.gz
tar -zxvf cmake-3.6.1.tar.gz
cd cmake-3.6.1/
sudo apt-get install checkinstall
sudo checkinstall
== Upgrade libwayland-dev and network-manager from PPA's ==
Upgrade libwayland-dev and related dependencies:
{{Input|1=<nowiki>sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update  
sudo apt-get install libwayland-dev
Upgrade network-manager and related dependencies:
{{Input|1=<nowiki>sudo add-apt-repository ppa:9v-shaun-42/networkmanager 
sudo apt-get update
sudo apt-get install network-manager
{{Tip|You may lose network connection after this step.  Reboot to fix.}}
== Install Qt 5.7.0 using Qt offline installer ==
Download and install Qt 5.7.0 to the default location /opt/Qt5.7.0
{{Input|1=<nowiki>wget http://download.qt.io/official_releases/qt/5.7/5.7.0/qt-opensource-linux-x64-5.7.0.run
sudo ./qt-opensource-linux-x64-5.7.0.run</nowiki>}}
Choose default options and include "Sources" option
{{Note|On my computer it appears to be stuck at 4%(dialog box doesn't respond), but it installs just fine if I wait.}}
== Install some build dependencies ==
{{Input|1=<nowiki>sudo apt-get build-dep kde-workspace qtbase5-dev</nowiki>}}
== Build Qtwebkit ==
Install dependencies for building Qtwebkit:
{{Input|1=<nowiki>sudo apt-get install flex bison gperf libicu-dev libxslt-dev ruby</nowiki>}}
Install git:
{{Input|1=<nowiki>sudo apt-get install git</nowiki>}}
Clone and build qtwebkit:
{{Input|1=<nowiki>git clone git://code.qt.io/qt/qtwebkit.git --branch 5.7.0
mkdir qtwebkit-build
cd qtwebkit-build
/opt/Qt5.7.0/5.7/gcc_64/bin/qmake ../qtwebkit
sudo make install
== Setup kdesrc-build and .kdesrc-buildrc ==
kdesrc-build needs xml-parser-perl so install it with the following command:
{{Input|1=<nowiki>sudo apt-get install libxml-parser-perl</nowiki>}}
Most of this section is taken from https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source and copied here for your convenience.  Be sure to set qtdir and kdedir as directed at the end of this section.
=== Git remote prefix ===
Let's setup a "kde:" prefix for git commands. Add the following text to your ~/.gitconfig:
<syntaxhighlight lang="ini">
[url "git://anongit.kde.org/"]
  insteadOf = kde:
[url "ssh://[email protected]/"]
  pushInsteadOf = kde:
=== Install kdesrc-build ===
''kdesrc-build'' is,  a user-space package manager, it is used to compile KDE-related projects from source and installs them into a designated directory.
Follow the given steps to set up kdesrc-build to install KDevelop into our $HOME directory:
mkdir ~/kdesrc 
cd ~/kdesrc 
git clone kde:kdesrc-build 
cd kdesrc-build 
cp kdesrc-buildrc-kf5-sample ~/.kdesrc-buildrc
# Install a symlink of kdesrc-build to a location in PATH
mkdir ~/bin 
ln -s $PWD/kdesrc-build ~/bin 
export PATH=~/bin:$PATH
You will need to append the line <pre>export PATH=~/bin:$PATH</pre> to <pre>~/.bashrc</pre> so kdesrc-build is available in PATH whenever you open a terminal.
'''Configure kdesrc-build
Replace <pre>/path/to/kdesrc-build/kf5-qt5-build-include</pre> with <pre>~/kdesrc/kdesrc-build/kf5-qt5-build-include</pre> in ~/.kdesrc-buildrc file
Add <pre>ignore-kde-structure true</pre> and <pre>make-options -jN</pre> to the global section in ~/.kdesrc-buildrc
  ignore-kde-structure true
  make-options -j5 # NOTE: 5 is the number of jobs, this should usually be (number-of-cpu-cores + 1)
  #stop-on-failure        true        # Stop kdesrc-build
end global 
Set qtdir to output of <code>qmake –v</code> minus the lib
    kdedir /opt/kde-5 # Where to install KF5-based software
    qtdir /opt/Qt5.7.0/5.7/gcc_64    # Where to find Qt5
{{Remember|Make sure you have write access to the directory specified by kdedir!}}
===Setup work around for baloo compilation error ===
Add the following to ~/.kdesrc-buildrc to work around the compilation error with baloo:
  options baloo
      cmake-options -DCMAKE_CXX_FLAGS="-lc"
  end options
== Build plasma-desktop ==
Install dependencies to build plasma-desktop:
{{Input|1=<nowiki>sudo apt-get build-dep polkit-qt-1
sudo apt-get install libgif-dev libnm-glib-dev "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev libxi-dev libattr1-dev liblmdb-dev libxapian-dev
Download and install some packages from Xenial:
{{Input|1=<nowiki>mkdir extra-deb
cd extra-deb
wget http://mirrors.kernel.org/ubuntu/pool/main/libx/libxkbcommon/libxkbcommon-dev_0.5.0-1ubuntu2_amd64.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/libx/libxkbcommon/libxkbcommon0_0.5.0-1ubuntu2_amd64.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/libe/libepoxy/libepoxy-dev_1.3.1-1_amd64.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/libe/libepoxy/libepoxy0_1.3.1-1_amd64.deb
dpkg -i *.deb
Finally, we can build plasma-desktop:
{{Input|1=<nowiki>kdesrc-build --include-dependencies plasma-desktop</nowiki>}}
== Build some extra applications ==
You may want to build some base applications and can do so with:
kdesrc-build applications
You can use kdesrc-build to build other applications.  For example, to build kdevelop:
kdesrc-build --include-dependencies kdevelop
