Many Linux distributions include KDevelop by default, and most have a package management system that enables you to easily install KDevelop. Generally, you should install from the package management system.
If for some reason you cannot or do not want to use your distribution's packaging system (outdated packages, no packages), for versions of KDevelop since 5.0, you can also find a cross-distribution binary (AppImage) here.
sudo apt-get install kdevelop
zypper install kdevelop5
KDevelop, KDevelop-php (with docs) and KDevelop-Python are in the [extra] repository. To install any just type:
pacman -S kdevelop kdevelop-php kdevelop-python
The latest version of KDevelop, KDevelop-php (with docs), and KDevelop-python packaged for Fedora is contained in the default repository and can be installed using:
dnf install kdevelop
dnf install kdevelop-php
dnf install kdevelop-python
or by installing the above packages through the Dnfdragora package manager.
KDevelop, KDevelop-php (with docs) and KDevelop-Python are in the kde overlay. To install any just type:
layman -a kde emerge -av kdevelop pacman -av kdevelop-python
You can download the KDevelop for Windows installer from the KDevelop download page.
KDevelop can also be compiled from source on Windows via KDE's Craft tool. This tool will set up a development environment (including a Qt + KF5 build), and then compiles & install KDevelop. To get started, visit the Windows build instructions.
To compile & install kdevelop just type this into your command window:
Run kdevelop by just typing
There's a homebrew repository for Kate and KDevelop. See installation instructions there.
You can compile it like any other KDE project: See the KDevelop-specific TechBase instructions instructions or the Getting_Started/Build general instructions general build instructions for KDE projects.
