When I first wrote this article, it was lean and mean and simple to understand. And it was good for all distributions. Now I have the impression of a fat pig when I read this article. I pledge for removing the usual sources of error, e.g. the many subdirectories. Why do we need a directory KDE, for example ? If a tutorial is not simple, it is not done.

For example it *is* nessecary to install qt-copy, even if you keep it in the source directory (which leads to 394583069845 error messages on the console during the install). And kdelibs won't build unless something unknown is done with strigi - if it is installed into KDEDIR, it isn't just found.
the heading says pre-requirments are to read "Anonymous SVN Quickstart Guide" first. but the things it does are mostly done in this guide(but a little differently). for example the "Anonymous SVN Quickstart Guide" has you just svn a bunch of stuff.... but that all ended up in the wrong place cause in this guide the svn'd stuff needed to go to "kde-devl"-user's dir not the normal user dir..
when I wrote this article, it was lean and simple. It has been improved somewhere, but on most places worsened. An example is the directory structure (to get to qt-copy: cd && cd qt-copy; to get to kdelibs: cs && cd kdelibs; to get to kdepim: cs && cd KDE && cd kdepim - no one understands this!!!). Another example is cs and cb which is quite unnecessary as my initial article shows. But of course, with the complexity as the article has NOW, it IS necessary.
Why do you spoil a simple article so that even I no longer find my own subdirs ? --Tstaerk 10:25, 28 May 2007 (CEST)
svn co .../kdelibs mkdir build-kdelibs cd build-kdelibs cmake <options> ../kdelibs make install
This should be simplified, it should be made much easier to understand, with more technical on info later on. I find it hard to just follow it along. Remember, you guys are trying to help out would-be developers, so there can be more of them (good). With guides like this, and guides that don't exist, the new developers will be overly confused (like me) and will probably turn the other way (bad). I don't know, maybe it's just me that finds it too complex to understand....
A: This is not a typo. Read the article about setting up your .bashrc. Both cs and cb are bash functions, used to change to the KDE source directory and KDE build directory respectively.
A: No. The shell function cmakekde handles this, have a look at the file .bashrc.
When installing KDE4, I strongly recommend installing all tools (like dbus and cmake) and kde packages into the same place, e.g. ~/install. Qt is the only exception.
The reason for this is because if you install some packages to ~/kde and some to /usr/local and maybe one in /usr then cmake will generate errors like:
-- It is impossible to order the include directories.
This is not a fatal error, so you will still be able to compile, but you will possibly be using the wrong versions of libraries and this will product problems that are very hard to diagnose.
You may not experience any problems when installed like I advise not to, however I have and you might too in some typical situations.
The CMake modules should be installed local into ~/install/cmake/modules or similar. When following the current instructions 6.1: Install additional CMake modules, it's impossible to do a non-root installation, because "kdelibs/cmake/modules/cmake_install.cmake" wants to install the modules to "/cmake/modules". (I didn't install CMake local, because my system already provided CMake > 2.4.3).
I've already tried to do this, fiddling around with CMAKE_MODULE_PATH and DATA_INSTALL_DIR but couldn't get it working.
Does anybody know how to do this properly?

Since the patents expired, why not use giflib?
In Qt part I had problems with error like this: QtForum thread. I had GCC 3.3.X installed. Using -pch flag (as in recipe) get me errors. Someone friendly gave me tip on #kde-devel not to use this flag, although I didn't test it. Instead I've just updated gcc and g++ from debian repositories. Newer version works fine as "Precompiled headers are supported in GCC (3.4 and newer)" Wikipedia pch.

If there was a line at the top like:
sudo apt-get install libaaa-dev libbbb-dev ...-dev ...
This would be very useful and save hours. Is this something we should do?
after running 'su - kde4' and 'export' i saw that no variables in .bashrc were set, instead the old one (of the system) where set. I tried 'su kde4' and it worked fine. Why is that?
I'm running gentoo 2006.1 amd64
Are "-pch" and "-qdbus" really needed? The configure script shows that they're enabled by default. --McEnroe 16:49, 19 April 2007 (CEST)
It would be nice to know how much space (roughly, in GB) you need for a setup to build and run the basic things and packages. --Liquidat 03:08, 7 June 2007 (CEST)
With the kdesupport package I have an install error:
CMake Error: Error in cmake code at
FILE cannot create directory: /usr/lib/qt4/plugins/crypto. Maybe need administrative privileges.
Current CMake stack: /media/local/kde-devel/kde/build/kdesupport/cmake_install.c make;/media/local/kde-devel/kde/build/kdesupport/qca/cmake_install.cmake;/media/ local/kde-devel/kde/build/kdesupport/qca/plugins/cmake_install.cmake;/media/loca l/kde-devel/kde/build/kdesupport/qca/plugins/qca-logger/cmake_install.cmake
make: *** [install] Error 255
Why is it trying to install that system wide?
Once the patches have been applied, we then set up the build using the configure script (line 5-7). Finally, we build the minimal requirements for KDE (line 8)...
It should be 5-6 for configure and 7 for make.
Explanation is wrong because there is no make install command. And this directory will be used directly. But in the article: "...we build the minimal requirements for KDE (line 8) and install (line 9-10) Qt". But in lines 9-10:
Best regards, powerfox.
Why does the recipe for kdesupport only say "cs" before getting the source and building while the "cmakekdeall" function in the example .bashrc says "cs KDE/kdesupport && svn up && cmakekde"?
It should either use the KDE subfolder or it shouldn't but now I'm confused as to which of the two is right.
(sorry for grammar errors if they occur) So,
I,m using Kubuntu Gutsy Gibbon and I had problems with soprano library at installing kdelibs.
cmakekde requires to install kdelibs the version of soprano library, which does not exist in ubuntu repositories. The needed version you can find e.g. here: http://ubuntu2.cica.es/ubuntu/ubuntu/pool/universe/s/soprano/
From this website you have to download libsoprano-dev and libsoprano4 having the same suffix (e.g. ubuntu1~gutsy1_all.deb if you are using Kubuntu Gutsy Gibbon).
Go to directory where you downloaded packages and install each package using dpkg ( I have forgotten the order, so try and when something goes wrong, dpkg shows an information and proposes a solution).
After this remove ~/kde/build/KDE/kdelibs/CMakeCache.txt and try again to install kdelibs.
Good luck :)
Following the article I get to (in order):
-modify the .bashrc file with the one provided (which has a wrong "export QTDIR=$HOME/qt-copy") when everything else in the article uses "~/kde/src/qt-copy" or "~/kde/build/qt-copy" (I don't really understand which, but sure not "~/qt-copy"
-go to the console and do:
svn checkout svn://anonsvn.kde.org/home/kde/trunk/qt-copy
../../src/qt-copy/configure -largefile -phonon -qt-gif -openssl -opengl -glib -prefix $QTDIR
At this point the make says: "no objdir found. Tried /home/kde4/kde/build/qt-copy", which I have no idea what means, but anyway is not an usual message of the "make" command.
Try to follow the article to convince yourself. Also these smart command like cs, cb and the like don't work if they are called from inside a script, and too mysterious, so I would really like the thing a little more verbose and less high level smart shell tricks. Alex
