Description Rex Dieter 2008-10-28 13:03:35 EDT
We can reproduce this on F-9 too:
$ yum install kdebase-workspace
$ kcmshell4 kdm
(click Cancel)
kcmshell4: symbol lookup error: /usr/lib64/libldap-2.4.so.2: undefined symbol: ldap_int_tls-destroy

Wierd, any ideas what's going wrong here?
Comment 1 Rex Dieter 2008-10-28 14:06:09 EDT
oops, make that: ldap_int_tls_destroy
Comment 2 Jan Safranek 2008-10-31 09:08:23 EDT
I installed fresh yesterday's rawhide and I can't reporoduce the bug. kcmshell4 kdm shows lot of output, but in the end I can't see any symbol lookup error. I even tried to set up the authentication to take users and credentials from ldap, still without aforementioned error.

I have:

Do you have anything done with LDAP, e.g. user authentication?

If I understand it correctly, kcmshell4 just loads the configuration tool from /usr/lib64/kde4/kcm_kdm.so, right? Could you please post result of:
ldd -r /usr/lib*/kde4/kcm_kdm.so
ldd -r /usr/bin/kcmshell4
cat /etc/nsswitch.conf
rpm -qa | grep ldap

Really?  hitting the "Cancel" button doesn't produce the error?
We have 2 devs that *can*, interesting...

strace log

I finally reproduced the bug, but I still do not have any idea why someone wants ldap_int_tls_destroy and why the linker does not resolve it...

ldap_int_tls_destroy is internal ldap function, it's not in public include files in openldap-devel package and nobody outside openldap should ever use it.
Comment 6 Kevin Kofler 2008-11-04 11:33:34 EST
Looks like libldap isn't finding its own symbols for some reason I don't understand.
Comment 7 Ngo Than 2008-11-04 11:34:54 EST
Jan, ldap_int_tls_destroy is not used in KDE. It seems a issue in linker

stderr with LD_DEBUG=all

LD_DEBUG=all stderr output of 'kcmshell4 kdm'
Comment 9 Jan Safranek 2008-11-05 06:54:44 EST
This is fixed in kdebase-workspace-4.1.2-11.fc10, together with bug #457638.
Comment 10 Rex Dieter 2008-11-05 08:57:38 EST
Not exactly fixed, we only put in a crude workaround (by manually linking kcm_kdm against openldap), I'd prefer a proper fix... reopening for posterity.

(I'm ok with leaving this closed too, if that's what others would prefer)
Comment 11 Jan Safranek 2008-11-06 10:19:14 EST
Can't say what is wong. If I set LD_DEBUG=all, I can see that e.g. symbol ldap_int_inet4or6, required by libldap-2.4.so.2, is found in the same library:

symbol=ldap_int_inet4or6;  lookup in file=/usr/lib64/libldap-2.4.so.2 [0]
binding file /usr/lib64/libldap-2.4.so.2 [0] to /usr/lib64/libldap-2.4.so.2 [0]: normal symbol `ldap_int_inet4or6'

But with ldap_int_tls_destroy the linker does not even try to look into libldap-2.4.so:

symbol=ldap_int_tls_destroy;  lookup in file=/usr/lib64/libkdeinit4_kcmshell4.so
symbol=ldap_int_tls_destroy;  lookup in file=/usr/lib64/libkparts.so.4
(lot of libraries, libldap-2.4.so is not there)

If I try another binary, which links to that symbol (e.g. ldapsearch from openldap-clients.rpm), I can see no problem when resolving ldap_int_tls_destroy:

symbol=ldap_int_tls_destroy;  lookup in file=/usr/lib64/libldap-2.4.so.2 [0]
binding file /usr/lib64/libldap-2.4.so.2 [0] to /usr/lib64/libldap-2.4.so.2 [0]: normal symbol `ldap_int_tls_destroy'
Comment 12 Bug Zapper 2008-11-25 23:22:38 EST
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.

Comment 13 Rex Dieter 2009-03-17 16:05:06 EDT
Looks like kde-4.2's reduced linkage made this go away.  I'll take the liberty of closing this.  (Feel free to reopen if anyone disagrees)
