Since the latest update of akonadi I was not able to run two akonadi instances with the same user anymore, so I switched to a setup using two users.
I have my main user (which I use for all daily tasks) and a devel user. My kde development happens with normal user, and the devel user is only used to run the trunk versions of the parts I'm working on. I.e. currently I'm working on an app using akonadi and nepomuk, so I run another instance of akonadi and nepomuk with the devel user (because I need the latest Akonadi Agents).
This setup is fairly flexible as you can run full sessions with of the trunk version, without touching your working environment. On the other hand you don't need to run a full session, you can also simply run the programs you want with the devel user, from you normal working session with you standard user.
Layout:
-Main User: chrigi
-Development User: devel
-trunk KDEDIR: /opt/devel/KDE
-trunk sourcecode: /home/chrigi/devel/kde
MainUser (development and compiling)
First the setup of the MainUser which is used for the coding and compiling:
This follows mainly [[1]] but here is my exact configuration:
The following three scripts are used that the .my-setup file is sourced as soon as the sourcecode directory is entered:
append to .bashrc so the findup script is called on cd:
function cd() {
if test -z "$1"; then
builtin cd
elif test -z "$2"; then
builtin cd "$1"
else
builtin cd "$1" "$2"
fi
_f=`findup .my-setup`
if test -n "$_f" -a "$_lastf" != "$_f"; then
echo "Loading $_f"
_lastf="$_f"
source "$_f"
fi
}
/usr/local/bin/findup:
#!/bin/sh
arg="$1"
if test -z "$arg"; then exit 1; fi
while ! test -f "$arg"; do
cd ..
if test "$PWD" = "/"; then
exit 1
fi
done
echo $PWD/$arg
/home/chrigi/devel/kde/.my-setup
prepend() { [ -d "$2" ] && eval $1=\"$2\$\{$1:+':'\$$1\}\" && export $1 ; }

Some notes on .my-setup:
I removed all functions which I do not need. With this setup, it would also be possible to run programs which are compiled from trunk, directly as main user (chrigi). The KDEHOME is set appropriately therefore. However, you will run into problems when you try to run programs which use akonadi or nepomuk. Therefore we have the devel user.
With this setup you can already build kde from source, and install it to /opt/devel/KDE
Devel User (Running programs)
To run programs we need to setup the devel user:
First, create a new user called devel.
append the following to .bashrc:
prepend() { [ -d "$2" ] && eval $1=\"$2\$\{$1:+':'\$$1\}\" && export $1 ; }
## A script to setup some needed variables and functions for KDE 4 development.
## This should normally go in the ~/.bashrc file of your kde-devel user, so
## that it is executed when a session for that user is started.

## If you don't use a separate user, the first section with the
## environment variables should go into a separate script.

This is mainly a copy of the .my-setup script, which exports all needed variables, there are some differences however:
-all functions for compiling were removed (since compiling is don using the main user)
- some XDG variables are set:
# XDG #unset XDG_DATA_DIRS # to avoid seeing kde3 files from /usr (don not unset this, we need the dir for global mimetypes) #unset XDG_CONFIG_DIRS prepend XDG_DATA_DIRS $KDEDIR/share export XDG_CONFIG_HOME=$HOME/.config export XDG_DATA_HOME=$HOME/.local/share
This makes sure that the correct XDG directories are found, they are used for things like mimetypes, icons and also the akonadi-database.
-at the very end, the devel users uses a separate dbus session (over which programs communicate to akonadi and nepomuk). The code simply creates a new dbus session when first loggin in with the devel user, for all subsequent logins the same session is used.
Notes
By setting the XDG variables and dbus sessions correctly, I believe it should be possible to achieve the same as single user, I never got it to work however. All in all, this way there aren't really any drawbacks in productivity by using a second user. The only difference to my previous setup is, that the akonadi database is not the same as the one of my main user, which is probably good.
Using the Setup
First you get the sourcecode. Download it into the /home/chrigi/devel/kde directory, and compile it with 'cmakekde'.
See [[2]] for further info on building kde.
After a first run of cmakekde you can also use Kdevelop to build and install things. If you select the existing build directory in /home/chrigi/devel/kde/build all neede cmake variables will be found (of course you could also set them manually).
To run the compiled program use a tool called 'sux' (see [[3]] for further info). This is basically su with x forwarding.
All you need to do is:
-login with 'sux devel'
-run the program you want
If you are developing with akonadi it makes sens to start akonadi in a separate shell, so the output is not mixed with the one of your program:
-first shell: login with devel, start akaondi "akonadictl start" (will start the trunk version of akonadi, with the database of the user devel. Further it will also automatically launch nepomuk)
-second shell: login with devel, start your program which uses akonadi (the right akonadi instance will be found via dbus
Solitary session
