kdiff3 under kde4 for cfg-update [solved]

Message

petlab · Post by **petlab** » Sat Apr 11, 2009 4:37 pm

I have kdiff3-0.9.95 installed, and it runs fine for users, but not for root. I use cfg-update, so I need to use it as root. I'm in X as my regular user, running cfg-update as root in a Konsole.

Code: Select all

# kdiff3 --version
Qt: 4.5.0
KDE: 4.2.1 (KDE 4.2.1)
kdiff3: 0.9.95

When I run it from konsole, nothing appears to happen. I tried using options, with no effect. Any ideas? TIA

Code: Select all

# kdiff3 --display :0.0

(still nothing)

have you tried to run it via kdesu?

Code: Select all

kdesu cfg-update

Yes, I did that from a konsole. No effect. The thing is, it used to work fine in 3.5.10. I simply used

Code: Select all

# cfg-update -u

from a konsole and it worked. I think I'll investigate the 3v5 / 4v2 issue some more.

But did you run it via kdesu as a non-root user?

No, I didn't. How would you do that?

Code: Select all

(run) kdesu konsole??
  (run) kdesu cfg-update??

running kdesu cfg-update produces no output. either from "run command" or from a user Konsole.
I tried a kdesu konsole from my regular user, and

Code: Select all

  # cfg-update -u -t /usr/kde/4.2/bin/kdiff3

and got an error:

Code: Select all

In kdiff3 you select the lines that you want to keep.
  When done, click the save button and exit kdiff3!
  When you exit kdiff3, cfg-update will finish the update...
* GUI not available, unable to run the mergetool set in /etc/cfg-update.conf!
  Run cfg-update from within an X-terminal if you want to use a GUI mergetool.
  If you are getting this from within an X-terminal, you should try running
  "xhost +localhost" as the user who started the X-server.
  If you use this script on a system without an X-server you should permanently
  set the MERGETOOL variable in /etc/cfg-update.conf to vimdiff or sdiff.
  I recommend the more advanced vimdiff on systems without an X-server.
  See http://people.zeelandnet.nl/xentric for vimdiff usage instructions.

try this

(use the -t option to see console output)

Edit: I just installed cfg-update and found out it got stuck while invoking kdiff3 (but "kdesu kdiff3" starts kdiff3 as super user, maybe a cfg-update issue?), maybe one should try to compile kdiff3 with the "debug" use flag to find out why (sorry I forgot, the last time I used cfg-update I used it under kde 3.5

, today I prefer "etc-proposals"), but

works as a normal user from my terminal.

Ahh, Thanks! Well, it must be my riced system then, because

Code: Select all

kdesu -t "cfg-update -u -t /usr/kde/4.2/bin/kdiff3"

does work, but kdiff3 still doesn't appear. I had investigated the kde4 'rewrite/port/version' of kdiff3, but it was 'too hard' for me to install. I'll have to look at that again.

stan666 · Post by **stan666** » Wed May 06, 2009 6:27 pm

Does

Code: Select all

sudo cfg-update -u

work for you?

Edit: This bug seems to be related to the issue http://bugs.gentoo.org/258384
Edit: have you tried to use the kdiff-0.9.92 from slot "0"(emerge kdiff3:0)?

petlab · Post by **petlab** » Wed May 06, 2009 7:24 pm

Yeah, that works nicely!

FYI I have set my /etc/cfg-update.conf to use

Code: Select all

MERGE_TOOL = /usr/kde/4.2/bin/kdiff3

during my investigation of this. However, finding the binary never was the problem.

EDIT: I have 0.9.92-r1 installed. I see from the bug that the 'new' version works with kde4 so I'll try that.

petlab · Post by **petlab** » Wed May 06, 2009 9:00 pm

Emerging the newer version (0.9.95) repaired my problem. Now I can use cfg-update from a Konsole, as root, and Kdiff3 starts up. That's just what I needed!

BTW I am using USE="kdeprefix" and I have kdelibs-3.5.10 pulled in along with my kde4.2 installation. My kde4.2 comes from the overlay called kde-testing. I'm on ~~~x86. Thanks for your help, marking as [solved].

petlab · Post by **petlab** » Sat Sep 12, 2009 8:33 pm

I am on a new system now, ~amd64. I am still using

Code: Select all

sudo cfg-update -u

from a konsole, with kde-4.3.1 and kde-misc/kdiff3-0.9.95-r1. Works great. This post came up because I originally used just

Code: Select all

cfg-update -u

because I am normally root in a console after emerging a package. Originally, it worked. Something must have changed in one of the programs to cause me to need to # sudo.
