I have just installed POV-Ray 3.6 for Linux. When I try to do the KDE
integration, I get the message:
______________________________________________________
POV-Ray 3.6 installation
==========================
------------------------------------------------------
installing KDE integration for user 'ricky'...
could not determine user KDEHOME directory.
make sure KDE is correctly installed
______________________________________________________
As far as I can tell, KDE is working fine. The POV-Ray test run ran fine,
although the output window was strangely transparent.
OS: openSUSE Linux 12.1
Hardware: HP Pavilion dv5030us Notebook PC (32 bits, as far as I'm aware)

In a terminal window, what do you get if you execute:
echo $KDEHOME
?
Just a guess, but it looks like POVRay may be trying to use that to
determine the user's home directory. (Not a KDE user myself so I don't
know that that's what KDEHOME is supposed to be, but it seems a
reasonable guess).

It's blank. I did find a directory .kde4 in my home directory, and I wonder if
it's supposed to be set to that.
As far as learning the innards of KDE, I'm not sure where to start. There's so
much documentation and so little direction.

I'm not sure, but a quick google search found a result that showed KDEHOME
pointed to a .kde2 directory in someone's home directory - I'd try
pointing it at that .kde4 directory and see if that works. Seems a
reasonable thing to try.

That didn't work. I edited the install file to set KDEHOME directly, and it ran
without errors.
Now, I'll need someone to tell me what I should be seeing differently.

In Linux, remember that just setting the variable in a terminal doesn't
get the setting to propagate to the parent environment. You need to put
it in eg. the .bashrc file and then log out and back in - or set it in a
shell window, export it (if you're using bash), and then run the command
in the window.
Environment variables in Linux (and Unix, for that matter) can be a bit
tricky. But if you don't do that, then when you run the program it isn't
going to see the variable and it'll behave as if it isn't set (because it
isn't in that particular terminal/shell).
But modifying the install file works. :) I worked with a guy who said
when he was in the Army, his CO frequently said "if it's stupid but it
works, it ain't stupid." - while I don't think that's *always* the case,
it's certainly true a lot of the time. :)

Hi,
I have been using Povray under KDE/Linux since many years and never had any
problems with it. Since you're using opensuse you should preferably let
zypper do the install for you. That way you'll get all files where they need
to be. It will also give you a .conf file under /etc/povray which is root-
only. As root you can edit that file to set/reset read/write options.
KDEHOME, as far as I know, is a relicq of "olden days". Povray can use a
folder with conf file under the user home folder
/home/<user>/.povray/3.6/povray.conf, but honestly, I have never seen the
use for it.
You also mentioned a transparent render window when povray is running. That
is a direct effect of the Povray display code being ancient compared to the
KDE display code. A simple workaround is to start a render with the -D
option, no display, and then open the image being rendered with gwenview.
Gwenview is a standard in KDE and can handle images that are incomplete.

Question, How did you install povray? and logged in as who?

On opensuse 10.x and up (I have been using it since 7.2 or .3) you can let
zypper do the job for you.
Oh and as a side note, Povray for Linux doesn't know or use any graphics
desktops. It just blurts out some graphics info in the general direction of
the screen and hopes it works out. My main render machine runs text-only.
If you have any more questions, just holler.

IIRC, the solution for that was to use the "-visual DirectColor" switch.

Could be. I haven't heard of it and obviously never used it.
