Hi,

I finally build KDE-SC on a KVM GUEST. I was able to launch it.
Ok. (that was the previous thread i opened, now solved).

I repeated the steps on a baremetal F17, same steps.
I am able to build KDE (both master and 4. but i am not able to launch it.
Master and 4.8 use different users.


.xsession-errors shows:

And dmesg shows:

KDE is installed in: /home/admin/kde (for master) and /home/user2/kde (for 4.8.5)

To launch KDE (i first choose wich one i will launch, for example 4.8.5):

# ls -l /usr/share/xsessions/kde-bleding-edge.desktop
-rw-r--r--. 1 root root 3978 Aug 11 13:38 /usr/share/xsessions/kde-bleding-edge.desktop

# head -6 /usr/share/xsessions/kde-bleding-edge.desktop
[Desktop Entry]
Encoding=UTF-8
Type=XSession
Exec=/home/user2/kde/bin/startkde-wrapper
TryExec=/home/user2/kde/bin/startkde-wrapper
Name=KDE Bleding Edge

$ ls -l ~/kde/bin/startk*
-rwxr-xr-x. 1 user2 user2 13666 Aug 11 16:49 /home/user2/kde/bin/startkde
-rwxr-xr-x. 1 user2 user2 544 Aug 11 13:39 /home/user2/kde/bin/startkde-wrapper

$ cat /home/user2/kde/bin/startkde-wrapper
#!/bin/sh
export KDEDIR="$HOME/kde"

AddToPath() {
eval "export $1=$2\${$1+:\$$1}" # prepend to existing path, if there is one
}

AddToPath PATH "$KDEDIR/bin"
AddToPath LD_LIBRARY_PATH "$KDEDIR/lib"
AddToPath QT_PLUGIN_PATH "$KDEDIR/lib/kde4/plugins:$KDEDIR/lib/qt4/plugins"
AddToPath PKG_CONFIG_PATH "$KDEDIR/lib/pkgconfig"
AddToPath CMAKE_PREFIX_PATH "$KDEDIR"
export XDG_DATA_DIRS="$KDEDIR/share:/usr/share"
export XDG_CONFIG_DIRS="$KDEDIR/etc/xdg:/etc/xdg"
export KDEDIRS="$KDEDIR"
exec startkde "$@"

These are the steps i used to build kde-sc, and the dependencies i isntalled:

STEP 0:

* Installed a fresh install to a baremetal host (Phenom II X3 710 + 8 GB RAM + SSD + HDD)
* Installed F17 X86_64, used the DVD MEDIA, Selected "Software Developement", customized
package and added "KDE Software Developement".
* Requiered space 31GB, when compiling everything.

STEP 1:

* Updated the system '# yum update' and rebooted.

STEP 2:

* Setup the system to build KDE-SC
* Originaly based from: http://techbase.kde.org/Getting_Started ... ons/Fedora
* Please note that you must yum-buildep one package at a time. If you specify more than one package,
yum-buildep will only resolve dependencies for the first one.

# yum-builddep qt
# yum-builddep kdelibs
# yum-builddep kde-runtime
# yum-builddep kde-workspace
# yum-builddep akonadi
# yum-builddep soprano
# yum-builddep kdeaccessibility
# yum-builddep kdeedu
# yum-builddep kdegames
# yum-builddep kdegraphics
# yum-builddep kdemultimedia
# yum-builddep kdenetwork
# yum-builddep kdepim
# yum-builddep kdepimlibs
# yum-builddep kdeplasma-addons
# yum-builddep kdesdk
# yum-builddep kdetoys
# yum-builddep kdeutils
# yum-builddep polkit-qt
# yum-builddep strigi

# yum install libkdcraw-devel
# yum install libksane-devel sane-backends-devel

NOW, SET UP RPMFUSION REPOS:

RPMFUSION: '# yum install ffmpegthumbnailer-devel'

# yum-builddep libkdcraw

RPMFUSION: '# yum-builddep ffmpegthumbnailer'

# yum install libgphoto2-devel
# yum install upower-devel
# yum install qt-devel-private
# yum install kdenetwork-devel
# yum install kate-devel

# yum install vlc-devel
# yum install scim-devel
# yum install json-c-devel json-glib-devel
# yum install qjson-devel

# yum install calligra-devel
# yum install hspell-devel aspell-devel xine-lib-devel xmms-devel xmms2-devel libtidy-devel marble-devel
# yum install simspark-devel


STEP 3:

# mkdir -p ~/kde
# mkdir -p ~/kdesrc && cd ~/kdesrc

# git clone git://anongit.kde.org/kdesrc-build.git ~/kdesrc

* Configure the kdesrc-build script.
* In my case, i selected all cpu cores, since the host is dedicated to this task.
* I also selected to build all items.

# ./kdesrc-build-setup

STEP 4:

* Compile KDESRC

# cd ~/kdesrc
# ./kdesrc-build

* The build should complete without any error.



STEP 5:

* DISABLE SELINUX, otherwise it will impede the execution of the recently
compiled KDE-SC, since it will be located on non standar directories.
Set it to PERMISSIVE.

* Configure the recently compiled KDE-SC as an option in KDM.
* KDM should be already installed.

Edit (or create, because it does not exist by default on DVD Media) the file:
# vi /etc/sysconfig/desktop

And add:

DESKTOP="KDE"
DISPLAYMANAGER="KDE"

STEP 6:

EXAMPLE USER: admin
KDE BINARIES: /home/admin/KDE

* Adding an entry in KDM:

# ls -l /usr/share/xsessions/
total 20
-rw-r--r--. 1 root root 3944 Jun 6 09:45 kde-plasma.desktop
-rw-r--r--. 1 root root 5841 Jun 6 09:45 kde-plasma-safe.desktop

# cp /usr/share/xsessions/kde-plasma.desktop /usr/share/xsessions/kde-custom.desktop

# /usr/share/xsessions/kde-custom.desktop

Defaults:
Exec=/usr/bin/startkde
TryExec=/usr/bin/startkde
Name=KDE Plasma Workspace

Change To: (example):

Exec=/home/admin/kde/startkde-wrapper
TryExec=/home/admin/kde/startkde-wrapper
Name=KDE Plasma (Self Compiled)

SETP 7:

* Create startkde-wrapper script to make recently KDM entry work

$ vi /home/admin/kde/bin/startkde-wrapper

export KDEDIR="$HOME/kde"

AddToPath() {
eval "export $1=$2\${$1+:\$$1}" # prepend to existing path, if there is one
}

AddToPath PATH "$KDEDIR/bin"
AddToPath LD_LIBRARY_PATH "$KDEDIR/lib"
AddToPath QT_PLUGIN_PATH "$KDEDIR/lib/kde4/plugins:$KDEDIR/lib/qt4/plugins"
AddToPath PKG_CONFIG_PATH "$KDEDIR/lib/pkgconfig"
AddToPath CMAKE_PREFIX_PATH "$KDEDIR"
export XDG_DATA_DIRS="$KDEDIR/share:/usr/share"
export XDG_CONFIG_DIRS="$KDEDIR/etc/xdg:/etc/xdg"
export KDEDIRS="$KDEDIR"
exec startkde "$@"

STEP 8:

* Reboot the system and if you get to KDM, select "KDE Plasma (Self Compiled)" in
session type and then login with user 'admin' (in this example).


STEP 9:

* use kdesrc-build srcipt.

Ah, the infamous oxygen.so crash caused when system wide and self compiled installs conflict.
Have you tried removing ~/.config/Trolltech.conf?
Also, when do you set the QT_PLUGIN_PATH and LD_LIBRARY_PATH variables? Is it before startkde is invoked?

Have you tried removing ~/.config/Trolltech.conf?

No, i started from scratch and built a smaller subset (26 items). (no qt)
I have an issue with kdeplasma-addons, but i will open a new thread and
seems very specific.

Also, when do you set the QT_PLUGIN_PATH and LD_LIBRARY_PATH variables? Is it before startkde is invoked?

To start KDE, i first add a .desktop file /usr/share/xsessions/
I copy a normal kde-plasma and change it to start ~/kde4/bin/startkde-wrapper
(modify Exec, and TryExec, and Name)
I create startkde-wrapper (as kde doc says).
SELinux is in permissive, of couse.
KDE is launched from KDM and it resides in ~/kde4

Basically, what i need is to reproduce Bug 294795 in a self-compiled KDE.

Okay, as long as you set your environment variables up at the top of startkde-wrapper it should be fine.
Good to see you managed to get it to launch.
