Setting up Kubuntu Hardy for Development

[bigj2632]

I was wondering is there a way to set up kubuntu to develop kde 4 apps or do i need to follow kde's guide to setting it up which requires me to compile kde from source.

I don't use KDE, but I doubt it's that complicated. Probably it's just a matter of installing build-essential and the Qt development packages for whatever language you'll be using. All the basics should already be in the repos.

I installed all the dev versions of pretty much all the kde4 files i could find also cmake, automake, build essential and what not. i know that if i install all that stuff in gnome it pretty much is set up to develop but when i try the kde tutorial off the website i get an error that it cannot find the some of the functions i am calling out wich means i think that it cannot find the dev files. Is there something i need to edit to make my computer find those files and allow me to compile successfully.

If you post the specific errors, someone might be able to recognize the problem. I've never tried KDE development, so I probably can't help you, but if you post error messages, someone else probably can.

Here is the error message:

I used the code from this page which is a basic hello world for kde4.

Thanks msserver for the try.

Save this to a file: (like "kde4dev.sh" for example)


#!/bin/bash

#this is shamelessly stolen by hayer form http://techbase.kde.org/Getting_Started/Increased_Productivity_in_KDE4_with_Scripts/.bashrc

prepend() { [ -d "$2" ] && eval $1=\"$2\$\{$1:+':'\$$1\}\" && export $1 ; }

# Qt
# only set Qt related variables if you compiled Qt on your own
# (which is discouraged). if you use the distro provided Qt, skip
# this section. Comment it if necessary.
export QTDIR=/usr/share/qt4
prepend PATH $QTDIR/bin
prepend LD_LIBRARY_PATH $QTDIR/lib
prepend PKG_CONFIG_PATH $QTDIR/lib/pkgconfig


# KDE
export KDEDIR=/usr/lib/kde4
export KDEHOME=$HOME/.kde4
export KDETMP=/tmp/kde4-$USER
mkdir -p $KDETMP
export KDEDIRS=$KDEDIR
prepend PATH $KDEDIR/bin
prepend LD_LIBRARY_PATH $KDEDIR/lib
prepend PKG_CONFIG_PATH $KDEDIR/lib/pkgconfig
prepend QT_PLUGIN_PATH $KDEDIR/lib/kde4/plugins


then open a console and type:


source kde4dev.sh


in this console the build command should now work!
(if it don't work anyway, assert that you have "kde4-devel" installed)

Thanks alot for your help you guys, Hayrola i tried that script you gave me and after a few modifications i got it working. FIrst off I just commented out the qt stuff, then change some of the kde variables

export KDEDIR=/usr/
export KDEHOME=/.kde

I tested this and it worked on intrepid so im not entirely sure on Hardy although i dont see why it would not work.
