Dynamic Linking Problems after Update 7.1 -> 8.0

[rfolkerts]

Hi,

yesterday I updated my Laptop (Thinkpad A30p) from PC-BSD 7.1 to 8.0. The Update went thru fine; on the first Reboot I choose the correct Resolution and the ati-Driver.

However, when I tried to Login to KDM the screen got black, I saw the "wait" cursor and then was at KDM again.

I switched to Text-Mode Console and checked my ~/.xession-errors - File.

I contains:

cat .xsession-errors
In order to search for a string in some files, use 'grep' like this:

grep "string" filename1 [filename2 filename3 ...]

This will print out the lines in the files that contain the string. grep can
also do a lot more advanced searches - type 'man grep' for details.
/libexec/ld-elf.so.1: Shared object "libxkbfile.so.1" not found, required by "setxkbmap"
/libexec/ld-elf.so.1: Shared object "libgthread-2.0.so.0" not found, required by "libQtCore.so.4"
/libexec/ld-elf.so.1: Shared object "libgthread-2.0.so.0" not found, required by "libQtCore.so.4"
/libexec/ld-elf.so.1: Shared object "libXaw7.so.7" not found, required by "xmessage"

However, the so-Files being complained do exist in /usr/local/lib.

ralf@pcbsd ~]$ ls -l /usr/local/lib/libxkbfile.so.1
-rwxr-xr-x 1 root wheel 153231 8 Feb 18:14 /usr/local/lib/libxkbfile.so.1
[ralf@pcbsd ~]$ ls -l /usr/local/lib/libgthread-2.0.so.0
-rwxr-xr-x 1 root wheel 19293 8 Feb 17:36 /usr/local/lib/libgthread-2.0.so.0
[ralf@pcbsd ~]$ ls -l /usr/local/lib/libXaw7.so.7
-rwxr-xr-x 1 root wheel 416731 8 Feb 18:09 /usr/local/lib/libXaw7.so.7

So, I checked if ldconfig was started during boot (on ttyv1) and the paths it shows:

Firewall rules loaded.
ELF ldconfig path: /lib /usr/lib /usr/lib/compat /usr/local/lib /usr/local/kde4/
lib /usr/local/lib/compat/pkg /usr/local/kde4/lib /usr/local/kde4/lib/kde4 /usr/
local/lib/compat /usr/local/lib/compat/pkg /usr/local/lib/mysql /usr/local/lib/p
th /usr/local/lib/qt4
a.out ldconfig path: /usr/lib/aout /usr/lib/compat/aout

So, /usr/local/lib is there - which looks OK.

Also, /var/run/ld-elf.so.hints looks OK (i.e. I do see /usr/local/lib in).

Then I disabled X11-Start by commenting out the ttyv8 in /etc/ttys, rebooted, and tried to run "startx". However, I didn't start but I got complaints re. missing Libs (similar to those from the KDM-Logon).

Finally, I set LD_LIBRARY_PATH to /usr/lib:/usr/local/lib -- and then startx went thru fine.

Does anyone have a hint where to look, what to check and how to "repair"?

I checked the Knowledge Base, FAQ and Wiki but didn't find anything that seemed helpful.

Would really be cool to get the Laptop back to work...

MTIA and Cheers,

I would think that it needs to be ld-pcbsd-elf.so.hints or ld-pcbsd-32.so.hints

Check that LD_ELF_HINTS_PATH in /etc/rc has the right path.

Should be

LD_ELF_HINTS_PATH=/var/run/ld-pcbsd-elf.so.hints or ld-pcbsd-32.so.hints

To be sure, invoke ldconfig -r /var/run/ld-elf.so.hints and check for the search directory. It should be

/lib:/usr/lib:/usr/lib/compat:/usr/local/lib

Hi,

thanks for the reply!

Well, I didn't find a LD_ELF_HINTS_PATH in /etc/rc.

Indeed, it does not seem to be defined/used anywhere in /etc as

root@pcbsd# find /etc -type f -exec grep -i ld_elf {} /dev/null \;

returns no matches :-(

Does this indicate that the /etc/rc is "bad" on my System? I does look OK; it's dated 01/01/2010 18:10 and has a size of 3664 Bytes.

The ldconfig -r looks ok; it even containts all those libs that upon starting X will not be founf any longer

/var/run/ld-elf.so.hints:
        search directories: /lib:/usr/lib:/usr/lib/compat:/usr/local/lib:/usr/local/kde4/lib:/usr/local/lib/compat/pkg:/usr/local/kde4/lib/kde4:/usr/local/lib/compat:/usr/local/lib/mysql:/usr/local/lib/pth:/usr/local/lib/qt4
[...]
145:-lgthread-2.0.0 => /usr/local/lib/libgthread-2.0.so.0
[...]
201:-lXaw7.7 => /usr/local/lib/libXaw7.so.7
[...]
207:-lxkbfile.1 => /usr/local/lib/libxkbfile.so.1
[...]

Oh... I just ran "startx" as root - and X started correctly.

So, it must be something wrong with my "ralf" User.

I checked my ~.profile and found

LD_ELF_HINTS_PATH="var/run/ld-pcbsd-elf.so.hints"
export LD_ELF_HINTS_PATH

Upon re-activating ttyv8 and reboot I am now able to Login to KDM :-)

Did the name of the hints-File change eventually in PC-BSD 8?

Thanks for the reply!

[Fatmice]

root@pcbsd# find /etc -type f -exec grep -i ld_elf {} /dev/null \;

That's too much to type. Try this instead!

grep -n "LD_ELF_HINTS_PATH" *

It will return line numbers of the file if anything matches.

LD_ELF_HINTS_PATH must be defined for stuff to work correctly.

Seems so.

Yeah but it's no good if the path to the hint file doesn't exist.

Seems so! I just found out from another user's reply that X11 moved from /PCBSD/local to /usr/local! So things spontaneously move around here...a lot it seems. So I found it's best to play it safe and never ever upgrade....because you get burn! :twisted:

Well, I prefer the find-way as it will also search in Subdirectories (i.e. in /etc/defaults and /etc/rc.d where such things might (also) be defined/used. As many things are in /etc/defaults/rc.conf (but might also be overridden in /etc/rc.conf) (at least on FreeBSD - but I think/hope it's not different in PC-BSD. I must admit I didn't check that yet as I only use the Laptop very seldom but normally use a FreeBSD Desktop) it's handy.

But that's just my personal taste, of course ;-)

There you go

grep -rn "LD_ELF_HINTS_PATH" *

For the most part things are the same.
