==Installing KDE SC and its Prerequesites==
+
<!--T:1-->
There are several ways to install KDE SC so that you can use and develop KDE software. Below are complete instructions for installing KDE4 on a Linux system based on whether you want an Official Release, a Nightly Build, Stable 4.x Release, or Master (master is the git equivalent to what was called "trunk". It is the most recent snapshot.

There are many different ways to become involved in the KDE Community, ranging all the way from a simply using our software through to being a core platform developer.
  
==Build Notes for Special Users==

<!--T:5-->
 +
You can find more general information on getting involved in KDE at the following links:
 +
* [http://community.kde.org/Getinvolved Getting Involved in KDE]
 +
* [[Special:myLanguage/Contribute|Contribute to KDE]]
  
* '''Distribution managers''' may be interested in [[Getting_Started/Build/KDE4/on_virtual_machines|installing KDE SC using a virtual machine]].
+
<!--T:6-->
* '''Core developers''' may want to use a [[Developer_Setups|common KDE developer setup]] (this page is not complete).
+
This section of KDE TechBase is designed to help get you started in participating in the technical side of the KDE community. It will explain to you how KDE Software is structured and built, and how you can participate by building KDE for yourself.
  
==Qt==
+
<!--T:7-->
 +
{{Note|'''Quickstart:''' If you are impatient to get started without understanding what you are doing then you can skip straight to using a [[Special:myLanguage/Getting_Started/Build#Scripted_Builds|Build Script]], but it is strongly recommended you read this documentation first.}}
  
''In each installation scenario above, Qt is installed in the most appropriate way.'' For your reference, there are three ways to install it:
+
== Using KDE Software == <!--T:8-->
  
; KDE-Qt '''(Recommended)'''
+
<!--T:9-->
:Previously known as qt-copy -- This is the minimum version of Qt any of your users are expected to have. It is also the recommended one. Some bugs may be fixed in new Qt, so you may have to work-around bugs in lower versions, including this one. However, it's generally considered more stable, since we manually sync releases from Main Qt, as well as our own patches which also fix bugs not already fixed in Main Qt.
+
If you just want to use stable KDE software for your everyday computing needs, then you do not need to build KDE Software for yourself. You should instead use the software installer provided by your Linux distribution to install KDE package.
  
; System Qt
+
<!--T:10-->
: Often the easiest way to go, because most people have it already, you may have to install the QCA plugin as root though. However, depending on how up-to-date your distribution is (most aren't) and if you are running KDE from master, then your Qt will probably be far too old.
+
The best place to learn how to do this is through your distributions normal support channels, although you may find some useful information on the following pages:
 +
* [http://www.kde.org/download/distributions.php Distributions shipping KDE]
 +
* [[Special:myLanguage/Getting_Started/Build/Distributions|Install KDE Software on Linux and BSD Distributions]]
 +
* [[Special:myLanguage/Projects/KDE_on_Windows/Installation|Install KDE Software on Windows]]
 +
* Mac OS X does not currently have an installer available for KDE Software, but you can simplify building it by using [http://mac.kde.org/?id=build MacPorts or Fink]
  
; Main Qt
+
== Getting Help == <!--T:11-->
: Get it straight from Nokia, experience the latest cool features and bugfixes (and regressions!). Bear in mind though, that applications which reside in master can only depend on a certain "highest" Qt version. This is because distributions either lag behind, or it is at an awkward time in the KDE Release Schedule, which could end up granting us a loss in stability. Other applications, like KDevelop, Amarok, and applications in playground, etc. have their own rules.
+
  
==Source Repository==
+
<!--T:12-->
 +
If you are looking for help in using the KDE Workspace or KDE Applications then please visit the [http://userbase.kde.org/ KDE UserBase].
  
Currently, KDE SC source code is [[Getting_Started/Sources/Anonymous_SVN|accessed using svn]], but in the future, we are migrating to Git. [[Getting_Started/Sources/Amarok_Git_Tutorial|Amarok has already migrated to Git]], as well as a few other modules (phonon, parts of kdesupport). Until we are fully migrated at least, it is recommended to use kdesrc-build if you can, as it takes care of all of this for you.
+
<!--T:13-->
 +
If you have any questions or problems with building or developing KDE Software please feel free to [[Special:myLanguage/Development/Getting_Help|ask for help]].  However, be patient while waiting for a response, and try to work through the problem yourself, we aren't going to do it ''all'' for you.  Working your way through and understanding why something doesn't work is a good way to learn how to do things the right way.
  
== Troubleshooting the build ==
+
== Browsing the code == <!--T:28-->
See [[Getting_Started/Build/KDE4/Troubleshooting|Troubleshooting]]
+
The KDE project is all free and open source. You can view its source code and make changes.
  
Compile and Linking errors are frequent sources of discouragement. Make careful note of the first occurrence of an error in your build process. It could be as simple as a bad environment variable, an unexpected version of a library or missing prerequisite.
+
<!--T:29-->
 +
http://projects.kde.org hosts the source for many KDE-related initiatives, including [https://projects.kde.org/projects/kde KDE itself].  Choose a piece of KDE such as KDE Libraries, then click Repository to browse its source. [[Getting_Started/Sources]] explains the organization of KDE source code.
  
Please review your logs and do searches for fixes. If you cannot find a solution, try [[Build/KDE4/Errors]], the IRC channel, and the mailing lists. You can post your detailed issue from [[Build/Stories]].

There are several possible ways to build and install KDE software and the method you choose depends on what you want to do with the software.  In particular if you are only wanting to build and develop a single application you may not need to build the entire KDE Development Platform to do so.  You can read more about this on the [[Special:myLanguage/Getting_Started/Build/Methods|Build Methods page]].

You probably won't need the latest bleeding-edge version of KDE with which to develop. Much of the code will be similar between versions and your patch might work.

Using KDE Software

If you just want to use stable KDE software for your everyday computing needs, then you do not need to build KDE Software for yourself. You should instead use the software installer provided by your Linux distribution to install KDE package.

The best place to learn how to do this is through your distributions normal support channels, although you may find some useful information on the following pages:

If you are looking for help in using the KDE Workspace or KDE Applications then please visit the KDE UserBase.

If you have any questions or problems with building or developing KDE Software please feel free to ask for help. However, be patient while waiting for a response, and try to work through the problem yourself, we aren't going to do it all for you. Working your way through and understanding why something doesn't work is a good way to learn how to do things the right way.

Browsing the code

The KDE project is all free and open source. You can view its source code and make changes.

http://projects.kde.org hosts the source for many KDE-related initiatives, including KDE itself. Choose a piece of KDE such as KDE Libraries, then click Repository to browse its source. Getting_Started/Sources explains the organization of KDE source code.

There are other utilities to browse the source code:

Building and Running KDE Software From Source

There are several possible ways to build and install KDE software and the method you choose depends on what you want to do with the software. In particular if you are only wanting to build and develop a single application you may not need to build the entire KDE Development Platform to do so. You can read more about this on the Build Methods page.

If you simply want to build one application, the simple tutorial Building an Existing Application might be enough already.


The following sections explain the steps you need to understand and give the instructions you need to follow to successfully build KDE Software from source:

Development Model

TODO: General introduction to the dev model, release cycles, etc.

Development Tools

There are a number of Development Tools that are either required or helpful when building KDE Software. For these you will usually want to use the stable packages provided by your distribution.

You may want to use a graphical IDE for your development work:

Contributing To KDE

Once you have a copy of KDE built you can then start contributing back to KDE. The pages below will help you find out how you can help make KDE even better.
