Configuration

I don't like to use the whole desktop, only single
kde applications. How do I do that ?
Running kde applications
without the desktop requires running some basic application like shown
below:
ipc-daemon2 &
Xwin -multiwindow &
kdeeinit --no-kded --nofork &

After that you can run any kde application

starting kwrite
kwrite

starting kate
kwrite

starting kdevelop
kdevelop

You may save some starting time by using the following
sequence:
kwrite --nofork &

This prevents that kwrite forks itself into the background and release
the shell, which is very time consuming. Instead it instructs the shell to
run the application independing from the shell, which goes much faster. (I
have measured 50% lower startup times for kicker) Please note, that the
--nofork isn't supported by all applications, konqueroer for example does
not switch itself into the background by default, so you have to start it
with:
konqueror &

How do I move/copy a cygwin-kde installation to
another computer ?
The regular procedure is splited into two
parts. Please note that this will only work between WinNT,Win2K and WinXp,
not between one of this and Wi n 9x.

Copy the whole directory tree containing the cygwin (by default
c:\cygwin) to the other computer.

Export the cygwin related registry settings in a file say
cygwin.reg, change the required path in the export file to the new
locations and apply the registry settings on the new computer by double
clicking on the file.

The relating registry key is located below
HKEY_LOCAL_MACHINE\Software\Cygnus Solutions.

How do I configure Printing in kde ?

Printing support in kde-cygwin is currently performed with the
ghostscript package.

Install the ghostscript-x11 and cygutils package, if not already
installed.

Edit the file /opt/kde3/bin/cygprint and change the related
variables for your settings. The possible values could be extracted from
the ghostscript
documentation.
# for network shares use "\\\\server\\share"
PRINTER="lpt1:"
PRINTER_TYPE=deskjet
PAPER_SIZE=a4

In the printing dialog, select "Print with external application" in
the printing dialog and enter cygprint and click "Print" to
perform the printing.
In case of errors you may inspect the file
/var/log/cygprint.log, which contains all output from the cygprint tool.

An example of the used printing script is listed below:
$ cat >/opt/kde3/bin/cygprint
#!/bin/sh
PRINTER="\\\\server\\share"
#PRINTER="lpt1:"
PRINTER_TYPE=deskjet
PAPER_SIZE=a4

LOG_FILE=/var/log/cygprint.log
echo $0 $* >>$LOG_FILE
if test -z "$1"; then
echo "usage $0 "
exit 1
fi
#$TMPFILE=$1
if test -n `echo $1 | grep "^/tmp"`; then
TMPFILE=$1.$$
else
TMPFILE=/tmp/$1.$$
fi
GS_PARAMS="-q -sPAPERSIZE=$PAPER_SIZE -sDEVICE=$PRINTER_TYPE -sOutputFile=$TMPFILE -dNOPAUSE -dBATCH $1"
echo "gs $GS_PARAMS" >>$LOG_FILE
gs $GS_PARAMS >>$LOG_FILE 2>&1

# in case of errors
if test "$?" != "0"; then
exit $?
fi

if test -f $TMPFILE; then
echo "/usr/bin/lpr -l -d $PRINTER $TMPFILE" >>$LOG_FILE
/usr/bin/lpr -l -d $PRINTER $TMPFILE >>$LOG_FILE 2>&1
echo "rm $TMPFILE" >>$LOG_FILE
rm $TMPFILE >>$LOG_FILE 2>&1
fi
exit $?

The default kde fonts looks very ugly - How could I
use Windows True Type fonts ?
Install the Windows True Type fonts
with the KControl font installer module.

You should change your current cygwin user to root
(old) Habacker:unused_by_nt/2000/xp:11002:10545:....:/home/Habacker:/bin/bash

(new) Habacker:unused_by_nt/2000/xp:0:0:....:/home/Habacker:/bin/bash

Create a new directory /usr/X11R6/lib/X11/fonts/truetype if
not existant from the bash shell:
mkdir /usr/X11R6/lib/X11/fonts/truetype

Run from kicker: System Administration->Font Installer or start
kcmshell system/kcmfontinst

Switch the view to the "extended mode", select the folder "truetype"
and click "Add".

Then go to the font directory of your windows installation, which
may depend on your os type and cygwin mount path settings e.g.
/cygdrive/c/Windows/fonts or
/cygdrive/c/WINNT/fonts or
/c/Windows/fonts or
/c/WINNT/fonts

select the desired fonts and select 'OK'.

Then press "Apply" to add the selected fonts to you KDE
installation. This step may need some time. Error messages while
performing this step could be ignored.

At last you can change KDE font settings with
kcmshell LookNFeel/fonts

If you are using kdebase release 3.1.4-1 or lower the newly
created font path isn't available for X in further X session, which
could be fixed by a little shell script inserted into
/opt/kde3/bin/startkde. How to apply:

Search for the following code lines in /opt/kde3/bin/startkde
#
# Check first for current resolution/depth
#
export X=`xdpyinfo |grep dimensions:|cut -d " " -f 7|cut -d "x" -f 1`
export Y=`xdpyinfo |grep dimensions:|cut -d " " -f 7|cut -d "x" -f 2`
export D=`xdpyinfo |awk '/depths/ {print $NF}'`
[ -e "$HOME/.skel/kdebase" ] || INITIAL="--force"

and append the following lines:
#
# add truetype font dir to font list exists (kcminit does not do this)
#
if test -d "/usr/X11R6/lib/X11/fonts/truetype"; then
xset +fp /usr/X11R6/lib/X11/fonts/truetype
fi

Now you are ready to use the Windows true type fonts. We have good
very experiences on Windows XP with the Verdana or Tohama fonts.

Does font anti-aliasing works ?

Currently no, but a good workaround is to use the Windows true
type fonts. See topic  The default
kde fonts looks very ugly - How could I use Windows True Type fonts
? .

How do I run a minimal KDE 3 ?
After you
have installed the latest qt and KDE release you can start a minimal KDE 3
with the following commands (for KDE >= 3.1.4):
export SHELL=/bin/bash
ipc-daemon2 &
XWin -multiwindow -clipboard &
kdeinit +kcminit &
kicker & (optional)
... &

No you can start any kde application from the bash shell by using
the following command:
&

where is the name of the requested kde application.

Troubleshooting

I get an error message "*** unable to remap ... to same
address as parent" What could I do ?
This error indicates an dll
loading problem while forking a cygwin process. This problem could be
solved by using the rebaseall utility of the rebase package which
is written by Jashon Tishler (application) and Ralf Habacker (rebasing
related win32 imagehelp libary replacement for all cygwin supported
platforms).

To fix this problem please install the rebase utility through the
cygwin installer (if not already present), stop all cygwin processes but
bash and run the following command (add -v if you like to get a detailed
list of the performed actions):
$ rebaseall [-v]

This command searches all installed dll's and take care, that dll's
does have uniq base addresses.

Windows XP note:
It may be required to restart your
computer due to a problem with the windows dll cache. If some of your
cygwin applications does not work as before rebasing, please restart.

Why must I run rebaseall after a clean install ?

This rebaseall command gives each cygwin related dll a uniq base
address to ensure an ordered dll loading in a process memory area.

By default the linker gives all dll's the same base address
(0x10000000), which could result in a "unable to remap" problem, when a
cygwin process tries to fork a child process.

BTW: I have heard, that this rebasing task is also done by other
windows installer, but they don't tell about this.

The cygwin window I used to kick off KDE is
outputting that it can't load a library, is that normal?
kdeinit,
kde's application launcher process starts application by forking itself
and loading the required application located in a shared library to reduce
memory consumption and startup time.

If kdeinit does not find such a dll, it prints out the informational
message "Could not load library! Trying exec....", then it tries to
fork and exec the required application directly.

Why do I get the message "It looks like
dcopserver is already running.." ?

Sometime users experienced the following message:
---------------------------------

It looks like dcopserver is already running.
If you are sure that it is not already running,
remove /home/de067018/.DCOPserver_minniti_127.0.0.1_0
and start dcopserver again.

---------------------------------

This error indicates that the dcopserver is still running probably from
a previous KDE session.

This could happen if one have started KDE before and the session is
broken by unusually user intervention lilke killing the xserver or an
internal failure (remember KDE is of beta quality).

In mostly cases you can fix this by starting KDE again. If this does
not help open the task manager and kill the dcopserver process.

Why do I get the message
"DCOPClient::attachInternal. Attach failed Authentication Rejected" ?

This may be file access problem in your home directory. See the
relating thread in the kde-cygwin mailing list AW:
DCOPClient errors in WinXP for further informations.

Why do I get the message "Error reading from
/home/.../.DCOPserver_..._127.0.0.1_0, didn't read the expected .. bytes"
?

This error message is caused by a text mounted entry in the cygwin
mount table. Make sure, that the root dir is mounted in bin mode.See the
following example, which shows a text mounted root path:
$ mount
c:\cygwin\usr\X11R6\lib\X11\fonts on /usr/X11R6/lib/X11/fonts type system (binmode)
c:\cygwin\opt\kde3 on /opt/kde3 type system (binmode)
c:\cygwin\bin on /usr/bin type system (binmode)
c:\cygwin\lib on /usr/lib type system (binmode)
c:\cygwin on / type system (textmode)
^^^^^^^^

Change the mount mode to binary with the following commands:
$ cd c:/cygwin/bin (or wathever your cygwin root dir is)
$ umount -s /
$ mount -s -b c:/cygwin /

Why do I get the message "cygheap_fixup_in_child:
Couldn't reserve ... bytes of space for cygwin's heap ..." ?
If
you got an error message similar to:
... cygheap_fixup_in_child: Couldn't reserve 9891792 bytes of space for cygwin's heap (0x61810000 < 0x6C0000 >) in child, Win32 error 487
c:\cygwin\....exe (3684): *** m.AllocationBase 0x0, m.BaseAddress 0x61810000, m.RegionSize 0x1B0000, m.State 0x10000

this indicates mostly a rebase problem. Cygwin tries to reserve an
amount of memory on top of the address area of the cygwin1.dll. If this
area is already allocated by another dll or shared memory segment, the
allocation fails and the above mentioned error is raised.
You can fix
this problem by rebasing all cygwin related dll's with a base address
below the cygwin1.dll itself.
rebaseall -b 0x61000000

Why do I get the error message "The application
failed to initialize properly (0xc0000005)..." when running applications I
have self compiled ?

This error indicates a problem of the ld auto-import support and newer
gcc releases using readonly variables. To avoid this problem you should
uses a recent qt/cygwin releases (>3.3.3), which contains all required
support or add the required stuff by hand:

download the specific
ld linker script and either

add the following switches to your link line:
... -Wl,--enable-runtime-pseudo-reloc -Wl,--script,< YOUR_PATH >/i386pe.x-no-rdata

or use the following configure line
LDFLAGS="-Wl,--enable-runtime-pseudo-reloc -Wl,--script,< YOUR_PATH >/i386pe.x-no-rdata" .. configure ...

With cygwin 1.5.5-1 starting the small KDE desktop
works, but starting full KDE hangs - What could I do ?

Is seems that cygwin 1.5.5-1 contains a bug, which lets kcminit hangs.
Currently three workarounds are known:

Remove the term '+kcminit' from /opt/kde3/startkde.bat or
/opt/kde3/bin/startkde if you are starting kde from a bash shell. Please
note that this disables special keyboard layout settings, which is no
problem is you are using the standard keyboard.

downgrade to cygwin 1.5.4-1, which does not contain this error.

install a cygwin snapshot from http://www.cygwin.com/

wait for the next cygwin upgrade

After running startkde.bat under windows 9x I got
the following messages: Out of environment space - What can I do ?

The W9x dos shell default environment space is to small for kde.
To extend see Microsoft
Knowledge Base Article - 230205.

I have installed the KDE3 devel setup package, but I
cannot find any *.dll.a files in the kde's lib dir. What's going wrong ?

The *.dll.a files are so-called "import libraries" for the linker and
are symbolic links to the related dll. It seems that the inno setup
compiler is not able to deal with symbolic links. I will see how this
could be fixed in further releases.

A workaround is to use the following sh script, which recreates the
necessary links. Enter /opt/kde3/bin before running it.
for i in `ls *.dll`; do cd ../lib; j=`echo $i | sed \
"s,-[0-9.-]*dll,.dll,g;s,cyg,lib,g"`; ln -fs ../bin/$i $j.a; cd ../bin ; \
done

How do I debug the KDE3 start procedure in case of
problems ?
Requirements:

Please make sure, you have a full working cygwin and xfree
installation

Don't use rebased or rebinded kde dll's or applications, because
this could result in segfault problems. If you not know anything about
this terms, you can skip the next sentence. If you have rebased or
rebinded reinstall the KDE packages.

Lets start:

enter a bash shell and set kde related environment
export KDEDIR=/opt/kde3.4
export QTDIR=/opt/qt/3.3
export KDEHOME=/opt/kde3.4/home
export PATH=$KDEDIR/bin:$KDEDIR/lib:$QTDIR/bin:/usr/X11R6/bin:$PATH
export LTDL_LIBRARY_PATH=$KDEDIR/lib:$KDEDIR/bin:/usr/X11R6/bin
export LD_LIBRARY_PATH=$KDEDIR/lib:$KDEDIR/bin:/usr/X11R6/bin
export DISPLAY=127.0.0.1:0

start xserver
$ XWin -nowinkill -noreset &

try to start dcopserver
$ dcopserver

afterwards the following lines should be printed (note that the
printed pid numbers anonymous-xxxx are samples and may be
different for you):

_KDE_IceTransmkdir: Owner of /tmp/.ICE-unix should be set to root
DCOP: register 'anonymous-xxxx' -> number of clients is now 1
DCOPServer up and running.
DCOP: unregister 'anonymous-xxx'

additional the following files should be available (part of the names
may be different)

$ ls /tmp/.ICE-unix/ -l
total 0
srwxrwxrwx 1 1002 Kein 51 Jun 14 11:15 dcop2256-1024046152

$ ls al ~/.DCOP*
lrwxrwxrwx 1 1002 Kein 191 Jun 14 11:33 .DCOPserver_BRAMSCHE -> /home/habacker/.DCOPserver_BRAMSCHE_BRAMSCHE-0
-rwxrwxrwx 1 1002 Kein 55 Jun 14 11:33 .DCOPserver_BRAMSCHE_BRAMSCHE-0

Additional possible errors could be:

Why
do I get the message "It looks like dcopserver is already running.."
?

Why do
I get the message "DCOPClient::attachInternal. Attach failed
Authentication Rejected" ?

try to start kdeinit
$ kdeinit --no-dcop --no-kded

then the following lines should be printed (note that xxxx and
are placeholders):

kdeinit: launch -> klauncher (null)
kdeinit: Launched KLauncher, pid = xxxx result = 0

kio (KLauncher): kconf_update (pid 2736) up and running.
kdeinit: PID 2736 terminated.
DCOP: new daemon kded

start kwin
$ kwin &

then the following lines should be printed (note that the printed pid

DCOP: register 'anonymous-1380' -> number of clients is now 3
DCOP: unregister 'anonymous-1380'
DCOP: register 'kwin' -> number of clients is now 3
DCOP: new daemon knotify
DCOP: unregister 'anonymous-2056'
kdeinit: PID 2056 terminated.

If any of this messages are not printed or looks
different, than you have a problem with this step, for which you should
search the mailing lists or the foren.

I've got a message about a missing file 'cygpng12.dll' -
What could I do ?

That means you haven't installed one of the needed cygwin base
packages. You should start again the cygwin installer and install the
libpng12 packages.

General hint: If you are missing a file and don't know to which package
it belongs, enter it's name on http://cygwin.com/packages/. Then
it prints out the package(s) where this file belongs.

KDevelop

I can't create a new project - what's going
wrong ?
This could be a packaging issue. Try the following
command (requires an installed perl package) after installation of
kdevelop:
cd /opt/kde3/share/apps/kdevappwizard/
for i in ` grep -sHr kdevelop-3.0.0-r8 * | sed 's,:#!.*,,g'` ; do echo $i; \
perl -pi -e "s,/var/tmp/portage/kdevelop-3.0.0-r8/image/,,g" $i; done
