I am running FC4 and it has been running without problem until last night. I was messing around with Winetools and getting everything set up. I was also trying to install Gstreamer and having some problems with that installation and never got it completed. However now most applications that I try to run, usually games that are Linux based and downloaded and installed using yum, come up with an error message if I try to run them using a terminal, if I run them by clicking them I get nothing. Here is the message I receive:

[Will@localhost ~]$ neverball
Creating link /home/Will/.kde/socket-localhost.localdomain.
can't create mcop directory
[Will@localhost ~]$

Again, none of this started until last night, I tried to google it out and came up short on any solutions. I am still fairly new with Linux, I am running in Gnome, so I am not even sure why it shows a reference to KDE.

A reference to KDE means that the programs need some feature of kde in order to run. KDE has extensive libraries, for example - that is one of the reasons why a program can depend on KDE. Did you try removing ~/.mcop directory (with root privileges, with 'rm -rf /home/user/.mcop')? Sometimes attempts to install something from sudo/su mess up leading to overwriting user's settings with root-owned files with rw------- rights (no one can do anything, except root).

No, I just decided to re-install FC4, I didn't have it up and running long, but the programs where working before and I am not sure what I did to screw it up. Thanks.

I got exactly the same error, from exactly the same situation. After updating Fedora Core 4 with yum, I can't run games any more. I get the "can't create mcop directory" error.

I found some references which suggested to re-install the kdelibs package. I tried the latest version from download.fedora.redhat.com but no luck. Then I uninstalled it and tried the previous version and that didn't work either.

I don't want to completely re-install the OS, there has to be a solution.

Raskin is probably right. Check if the folder that could not be written to is already present and what its permissions are.

i have had the same problem (fc4). but a few minutes ago fedora released one update:


Update Information: Fedora Core 4 Update: arts-1.5.0-0.2.fc4

Programs using the arts library will crash, when the user
does not install kdelibs package.

Updated arts packages are now available that fix the problem.
