With a fresh install of CentOS 7 I’m going to try and install KDE (Plasma) 5.
For fun, I’ll try and make it available to all users from the /opt/ directory.
According to KDE Developers the reason why Plasma is not available from repositories is due to missing support for cmake 2.8.12+.
UPDATED – CMAKE 3.5+ is now available in the epel-testing repo! QT5.6 is now available as well!
SO! Step1: Install dependencies:
yum-config-manager --enable epel-testing yum install cmake3*, qt5-* ln -s /usr/bin/cmake3 /usr/bin/cmake
*cmake for centos7 does not install as `cmake’ but cmake3. I do not know why.
Test with “qtdiag” (should return 5.5.1) and “cmake3 -version”(should return 3.5.0)
To build latest* we need wayland. New(er) Wayland. Without building yourself from source, you can get it from jmliger’s copr. Once you have that saved in /etc/yum.repos.d/ you can simply
yum install wayland*
Step 2: Build KDE*
I chose to use the KDE src-build script to make life easier.
Note: my kdesrc-builrc file was in /opt/kde/sources/kdesrc-build/ and the contents are as follows:
global source-dir /opt/kde/sources build-dir /opt/kde/build kdedir /opt/kde/install log-dir /opt/kde/logs git-repository-base kde-projects kde: cmake-options -DCMAKE_BUILD_TYPE:STRING=debug cxxflags -pipe -DQT_STRICT_ITERATORS -DQURL_NO_CAST_FROM_STRING -DQT_NO_HTTP -DQT_NO_FTP -Wformat -Werror=format-security -Werror=return-type -Wno-variadic-macros -Wlogical-op -Wmissing-include-dirs -std=c++11 make-options -j4 ignore-kde-structure true stop-on-failure true end global include /opt/kde/sources/kdesrc-build/kf5-frameworks-build-include include /opt/kde/sources/kdesrc-build/kf5-workspace-build-include
In addition to the above official instructions, I needed bzr, and some other additional *-devel libraries (build with –debug flag to see what you’re missing)
