Hi i'm on Fedora 18 with gnome.
I'd like to use Amarok, i've installed it and when i run i get this message:

[root@localhost nico]# amarok
amarok: error while loading shared libraries: libQtWebKit.so.4: cannot open shared object file: No such file or directory

i check on-line the solution without any success.
How can i fix it?
Thanks

I would think you are missing the package containing it

this command will tell if it is on the system

Code: Select all

whereis libQtWebKit.so.4

on openSUSE the package is libQTWebKit4

here is the result:

[nico@localhost ~]$ whereis libQtWebKit.so.4
libQtWebKit.so: /lib/libQtWebKit.so.4 /usr/lib/libQtWebKit.so.4

so it seems to exist....any idea now?

the /lib/lib one sounds wrong, these are links and I think there should only be one

run

Code: Select all

ls -l /lib/libQtWebKit.so.4 /usr/lib/libQtWebKit.so.4
 ls -l /lib/libQtWebKit.so*
 ls -l /usr/libQtWebKit.so*


sorry i don't understand what i'm supposed to do.

run the 3 ls commands in Konsole and post the results here, like you did with the whereis command. I think the /lib/libQtWebKit.so.4 file will not exist or be a bad link and then I'll suggest you rename it and try running Amarok.

her you are:

Code: Select all

[nico@localhost ~]$ ls -l /lib/libQtWebKit.so.4 /usr/lib/libQtWebKit.so.4
lrwxrwxrwx. 1 root root 20 23 apr 00.11 /lib/libQtWebKit.so.4 -> libQtWebKit.so.4.9.2
lrwxrwxrwx. 1 root root 20 23 apr 00.11 /usr/lib/libQtWebKit.so.4 -> libQtWebKit.so.4.9.2
[nico@localhost ~]$
[nico@localhost ~]$  ls -l /lib/libQtWebKit.so*
lrwxrwxrwx. 1 root root       20 23 apr 00.11 /lib/libQtWebKit.so.4 -> libQtWebKit.so.4.9.2
lrwxrwxrwx. 1 root root       20 23 apr 00.11 /lib/libQtWebKit.so.4.9 -> libQtWebKit.so.4.9.2
-rwxr-xr-x. 1 root root 27704808 22 gen 20.43 /lib/libQtWebKit.so.4.9.2
[nico@localhost ~]$
[nico@localhost ~]$ ls -l /usr/libQtWebKit.so*
ls: impossibile accedere a /usr/libQtWebKit.so*: File o directory non esistente


what is result of command

Code: Select all

rpm -ql libQtWebKit4

Code: Select all

[nico@localhost ~]$ rpm -ql libQtWebKit4
il pacchetto libQtWebKit4 non è stato installato
[nico@localhost ~]$


it says it's not installed. Now i do not understand how is possible that is not installed while i see the library installed.

i've already downloaded the package from http://pkgs.org/download/libQtWebKit.so.4
and tryed to install but it says that is already installed:

Code: Select all

[root@localhost Scaricati]# rpm -Uvc qtwebkit-2.2.2-8.fc18.i686.rpm
Preparazione dei pacchetti...
   il pacchetto qtwebkit-2.2.2-8.fc18.i686 è già installato
[root@localhost Scaricati]# rpm -Uvc qtwebkit-2.2.2-2.fc18.i686.rpm
Preparazione dei pacchetti...
   il pacchetto qtwebkit-2.2.2-8.fc18.i686 (il quale risulta essere più recente di qtwebkit-2.2.2-2.fc18.i686) è già installato
[root@localhost Scaricati]#



different distros package thing differently, I gave you the package name openSUSE uses which is what I am familiar with

as root rename /usr/lib/libQtWebKit.so.4 (as the file it links to does not exist) then run Amarok

run the following 2 commands, they will show what package provides a particular file

Code: Select all

rpm -q --whatprovides /lib/libQtWebKit.so.4
 rpm -q --whatprovides /usr/lib/libQtWebKit.so.4

Code: Select all

[root@localhost lib]# rpm -q --whatprovides /lib/libQtWebKit.so.4
qtwebkit-2.2.2-8.fc18.i686
[root@localhost lib]#  rpm -q --whatprovides /usr/lib/libQtWebKit.so.4
qtwebkit-2.2.2-8.fc18.i686


this is fine.

Now i'm trying to rename the /usr/lib/libQtWebKit.so.4 as you said but i do not undestand if i have to change the name as the package which fedora says is not installed (libQtWebKit4) or to move out from /usr/lib directory into /usr because we find that

/usr/libQtWebKit.so* file or directory does not exist

He didn't tell you to rename anything, where did you read that? Just install the missing packages.

as root rename /usr/lib/libQtWebKit.so.4 (as the file it links to does not exist) then run Amarok

i've tryed to install again the missing packege downloading from the url i gave you but it says it's already installed

the best way to fix it would be to reinstall the package and hope this time it is correct
maybe even remove, then re-install

after reinstalling run

Code: Select all

ls -l /usr/lib/libQtWebKit.so.4

if it exists run Amarok

if not as root remove the bad file and then create a new file with a good link as root

Code: Select all

rm /usr/lib/libQtWebKit.so.4
ln -s /lib/libQtWebKit.so.4.9.2 /usr/lib/libQtWebKit.so.4
