The version I have is 3.3.2 which I took from a Fedora 3 CD. In Fedora 2
Skype opens with this version which I copied to slackware.

I tried both the dynamic and static version and I am getting the same error.

Re: Skype wont't open

[Peter]

Thanks,

so when using Skype I will just boot into Fedora 2 instead of Slackware 10.
In Fedora 2 Skype opened and run well as soon as I had a library from Fedora3 
installed. I can't install fedora 3 since the 2nd install disk I got is 
damaged and no replacement yet from the company I bought it.

Re: Skype wont't open

[Peter]

Is it possible that the kernel has something to do that skype will not open in 
slackware10 instead aborts with:

skype: relocation error: /usr/lib/qt/lib/libqt-mt.so.3: undefined symbol: 
XkbSetPerClientControls

My kernel in slackware10 is 2.4.26 whereas in Fedora2 where skype works 
flawlessly the kernel is 2.6....

What is that anyhow XkbSetPerClientControls ?

Besides having tried the static and dynamic version I tried as well the rpm 
version which I have in Fedora, made a tgz file with rpm2tgz and trying to run 
it I get the identical error message.

This result is somewhat puzzling, especially coming from the static version.

So I did a bit of checking, though, and apparently this message means that 
libqt-mt.so.3 is unable to find one of its symbols. In this case, the 
symbol should resolve to a call to libX11.so, so the problem is likely a 
version incompatibility between the libqt-mt.so.3 you are using and 
Slackware's libX11.so.

Probably the best workaround is to stop using the libqt-mt.so.3 you copied 
over from SuSE and find a version of libqt-mt.so.3 that is compiled for, 
and works with, Slackware 10. Then use the dynamic version of Skype with it.

In any case, it is all but surely not a kernel issue. It is some sort of X 
issue.

Thanks Ray!

I downloaded and installed the latest qt-3.3.3-i486-3.tgz from slackware.
There is no change, all installed skype won't open,  sames error message.
I checked the libX11 and the latest version is installed.

When i searched google for your error message some said it is a bug in qt, 
others say its because one has installed another version of qt and now has 
two versions installed.
I pointed you to an URL which menioned a spesific order of directory´s in the 
file /etc/ld.so.conf. here is what i used on my slack-10 system when i tryed 
skype.

/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib
/opt/kde/lib
/usr/lib/qt/lib
/usr/lib/xine
/usr/lib
/lib

I noticed in another message of your that what ls -al /usr/lib/qt retured, it 
was different to my origanal slack-10 install, i get;
/usr/lib/qt -> qt-3.3.2

I belive if you installed an rpm from fedora 2 then that could well be your 
problem.

Re: Skype wont't open

Thanks Adam!

My /etc/ld.so.conf is practically the same:

/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib
/opt/kde/lib
/usr/lib/qt/lib
/usr/local/tmake/lib
/usr/lib
/usr/local/ActiveTcl/lib
/usr/include
/usr/local/lib/sigc++-1.2
/lib

and ls -al /usr/lib/qt
/usr/lib/qt -> qt-3.3.3

After this installation of qt-3.3.3 I did ldconfig.

I have no other version qt installed.

ls /usr/lib/qt*
/usr/lib/qt:
README-QT.TXT  examples    lib      plugins
bin            extensions  mkspecs  tutorial

There should be no need to define qt at all as you define /usr/lib, futher 
more its the define order that matters according to others who have the same 
problem as you.

Ray mentioned dependancies that quite possably backs up the need to define 
libs in a spesific order to aviod such problems.

Re: Skype wont't open

[Peter]

Hi,

just wanted to report that I opened the dynamic version of Skype in knoppix 
3.7 by going into hard drive and directory where that skype is stored, then 
clicking on skype and it opened flowlessly.

That means to me that the problem is really in slackware.

Should one report it to them and where?

Not a trace left. Updated daily.

I put this now into ld.so.conf only with no change of the error message after 
doing ldconfig. This is anyhow the sequence put-in by slackware I think.

/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib
/opt/kde/lib
/usr/lib
/lib

and leaving /usr/lib/qt out I get:

file: No such file or directory


I have the strong suspicion the problem is in those libs in /usr/X11R6/libs.
Are they different from distro to distro?

This is the end of strace dynamic skype:

read(4, "&\0\0\0\1\1\22\t\0\0\0\0\0\0\0\0\0\0\0\0\0\0\1\0\0\0\0"..., 604) = 604

Re: Skype wont't open

[chuck gelm]

Hi, Peter:

  This 'skype' is rather new to me and I only have it working
well using Windows 2000 & Windows XP.  It 'works' with
Slackware v9.1, but the audio is not good.

I am suggesting that you try with a fresh install of
Slackware so that it will not be confused with a 'rpm'
install of libraries from another distribution.

  Skype 'works' for me when invoked from a Xwindow terminal.
My Xwindow environment is Gnome (Slackware v9.1 default).
I guess I installed (or it defaulted to) Skype binary into
/usr/local/bin.  I run Gnome in Xwindows, open a terminal
windows and enter 'skype'.  Viola! it runs.

OBTW, my brother has Skype running on at least one
desktop and one laptop under Slackware.  I'll BC:
him and maybe he can offer some help or hints.
John: This is 'linux-newbie'.
http://vger.kernel.org/majordomo-info.html

Are there archives of linux-newbie?

HTH, Chuck

I was seemingly missleading on saying that /usr/lib should have been enought, 
iḿ sorry to say but i seem to be wrong.

It is defined here as

/usr/lib/qt/lib
Once again i have qt-3.3.2.
I have tryed skype on another box with a clean slack-10 install and i do not 
get that message.

Anyway like i mentioned slackware-10 and skype do not really like each other, 
even if skype starts you need to tune things a lot to get it to even think of 
working.

I am quite sure someone on the skype site mailing list(s) would appricate that 
as a problem report Peter.
All it says to me is that an undefined symbol was discoverd-;)

I would advise you to use the Skype ¨echo123¨ test service to see if it works 
properly first before going any further.

I doubt its a slackware problem but an incompatablity problem with lib 
versions used by slackware, i would like to hunt down problems like this but 
i just dont have the time thesedays, i have to work for a living again -;) 

skype is reported to work under a default slackware-10 distro on the skype 
site and it does say what you need to do to get it going under slackware, if 
you reasd the mail on the skype site you will see that many people say that 
slackware is the most choosy when it comes to getting skype going.
Just why that is lord knows.

Hi,

Since it is assumed that the problem is in the /X11R6/lib libraries of 
slackware I replaced them with the ones from Fedora 3. It did not change the 
error message:

symbol lookup error: /usr/lib/qt/lib/libqt-mt.so.3: undefined symbol:

Since you seem to be the only slackware user with this particular problem one 
must presume its your system at fault and not slackware.
Installing incompatable system libs is not such a wise thing to do, you will 
break something or other in the process.

If one tryed to insmod a kernel module which depends on another module which 
has not yet been loaded one will get an undefined symbol error, that means 
modules need to be loaded in a certain oder to avoid that problem.
Now loading libs is eachtly the same, define them incorrectly and undefined 
symbols will appier.

I am certain you will get more help from the folks on the skype forums site.

I just moved that /X11R6/lib directory out of the way. Copied the one from 
Fedora over, tried skype, did not work, removed the Fedora lib and moved the 
original slack back. No harm done.
