Graham: thanks, I'll try that...I thought that SDKs are supposed 
to be released with each new R2 version?

For thumbnails I have Imagick binding.. But I must test it with Cheyenne 
yet.

CALL on a third party exe works, but that's not a solution able to 
scale high (not talking about the induced delay of creating and closing 
a process)

I've download latest REBOL in Xubuntu. Viewtop opened without problem 
but when I switched to console, nothing appeared. Because I deselected 
"show desktop on startup", now I cannot start REBOL at all. Any ideas?
At least I can run it from console. But I still wonder why it does 
not work from icon.

There is no console for linux...must use linux console.
if you want to see viewtop start rebol from console and type desktop
Once in viewtop try changing the settings back to "open vietwtop 
on startup"

I just wonder why clicking on the icon does not open rebol in linux 
console. but i have no problem running it directly from console
Henrik

it's probably simply piping to whatever console it was started from. 
since the linux desktop has no console, you won't see one.

Hm, when I select "Install now" option, I get "segmentation fault"

2.7.7?
I installed 2.76 on ubuntu no prob
Rebolek

[3508x2]
yes, 2.7.7
Maybe it's fine on Ubuntu, I'm using Xubuntu as the computer is really 
really old.

might be missing a library file...check the list of required libs...find 
it somewhere on rebol site???
Rebolek

It's just the installation, everything else seems to work fine

ldd lists dependencies in console, no?

Well, first I need to get Cheyenne running, so I'll check the dependecies 
later :)

I also installed it on a server version of ubuntu with xfce loaded 
on top...iirc had to add some libs

You mentioned older computer. Is Xubuntu less resource hungry than 
Ubuntu?
Rebolek
2-Feb-2010
[3516]
Yes, the XFCE desktop should take less memory and CPU than Gnome.
Pekr

And what about Kubuntu? (KDE)
amacleod

big and hungry
like gnome

heh, it's running in 856x600, I see such resolution for the first 
time

What is running?
Rebolek

sorry, the linux desktop
Pekr

linuxians try to be always different, hence such a resolution :-)

Hello. How can I create a REBOL service in Linux (i.e, something 
that can be run as a background process much like httpd via init.d)?
Henrik
2-Feb-2010
[3528x2]
I suppose you first try to create a script that is launchable via 
shell, and from then on, it should be the same as for any other service, 
depending on the distribution.
launchable = shebang line and all that stuff.
Barik

I have the #!/usr/local/bin/rebol line and such in there. The problem 
is that I'm not sure how to make the script then go into the background 
again like a daemon would do. It stays at the foreground when I call 
it from something like init.d.
Henrik

do you have the quiet option enabled?
Graham

[3532x2]
you can use screen or dtach

Okay, that may do what I need it to. REBOL does some interesting 
things which I haven't quite figured out when I do something like 
CTRL + Z, bg, etc.
Let me take a look at dtach.
Graham

I also use

./cheyenne &

in a shell script
Barik

[3537x2]
Might be an implementation issue for me then. Would the & trick work 
with a non-compiled REBOL script in the same way?
dtach seems to be working well for me. I might stick with it.

Barik: you may just need to redirect stdin and stdout, eg.  ./script.r 
>/dev/null </dev/null &
