User:Donnguyen/How to build KDE/Plasma 5 on Ubuntu 14.04 LTS
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.
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/ ./configure make sudo apt-get install checkinstall sudo checkinstall
Upgrade libwayland-dev and network-manager from PPA's
Upgrade libwayland-dev and related dependencies:
sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install libwayland-dev
Upgrade network-manager and related dependencies:
sudo add-apt-repository ppa:9v-shaun-42/networkmanager sudo apt-get update sudo apt-get install network-manager

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
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
Choose default options and include "Sources" option
Install some build dependencies
sudo apt-get build-dep kde-workspace qtbase5-dev
Build Qtwebkit
Install dependencies for building Qtwebkit:
sudo apt-get install flex bison gperf libicu-dev libxslt-dev ruby
Install git:
sudo apt-get install git
Clone and build qtwebkit:
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 make sudo make install
Setup kdesrc-build and .kdesrc-buildrc
kdesrc-build needs xml-parser-perl so install it with the following command:
sudo apt-get install libxml-parser-perl
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:
[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
export PATH=~/bin:$PATH
to
~/.bashrc
so kdesrc-build is available in PATH whenever you open a terminal.
Configure kdesrc-build
edit
~/.kdesrc-buildrc
Replace
/path/to/kdesrc-build/kf5-qt5-build-include
with
~/kdesrc/kdesrc-build/kf5-qt5-build-include
in ~/.kdesrc-buildrc file Add
ignore-kde-structure true
and
make-options -jN
to the global section in ~/.kdesrc-buildrc
global ... 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 qmake –v
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:
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:
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:
kdesrc-build --include-dependencies plasma-desktop
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
Set up environment to run plasma 5
Follow this guide to test your plasma 5 build: https://community.kde.org/Guidelines_and_HOWTOs/Build_from_source/Test_plasma
