I don't think it's problem with sane - simple-scan and Samsung utility will do the same. I have similar bug, with

netdiscovery: relocation error: /lib/tls/i686/cmov/libnss_files.so.2: symbol strcmp, version GLIBC_2.0 not defined in file libc.so.6 with link time reference

I also mailed Samsung tech support, so if i'll get any answer, i'll post it here

[daniel venema (d-venema)]

I also get the exact same error output on Lucid with my CLX-3175FN connected via LAN.
When I connect with USB, Karmic installs another printer and after that XSANE recognizes the scanner and scanning works.
So USB connection works for me, but fails when connected via LAN.

Also mailed Samsung last week.

[daniel venema (d-venema)]

Sorry, but I use Lucid (see my previous comment).

[daniel venema (d-venema)]

I just did some extra testing.
1) I installed Ubuntu Karmic in a VirtualBox.
2) After that I installed the Samsung Drivers as mentioned in the initial bug description above.
3) I started the Samsung Unified Driver Configurator from the Graphics menu.
4) I made sure I disconnect the USB cable, so the Samsung is only connected to LAN
5) Next, added the LAN printer with the Samsung Configurator. This works fine. Printer is found, recognized and installed.
6) Then I choose the flatbed scanner icon in the Configurator. What do you know....... the scanner is found over LAN connection!
7) Test scan with Xsane works perfectly.

Conclusion: something was changed in Lucid compared to Karmic.....

In Karmic: when I run xsane from a terminal I see some, maybe, interesting output:

"(xsane:2191): Gtk-WARNING **: GtkSpinButton: setting an adjustment with non-zero page size is deprecated"

It could be that this deprecated code in Karmic, is actually no longer accepted in Lucid but the Xsane code still contains the use of this function? And this may prevent the scanner from being found in Lucid?

[Alex Thurgood (alex-thurgood)]

Sigh, this bug also affects me, below is the output when starting xscanimage or xsane from a terminal in Ubuntu Lucid Lynx :

"netdiscovery: relocation error: /lib/tls/i686/cmov/libnss_files.so.2: symbol strcmp, version GLIBC_2.0 not defined in file libc.so.6 with link time reference"

I might add that this worked flawlessy with Karmic over the local network. I have tried re-installing the official Samsung drivers, and network enabled printing configuration works fine, the printer is detected and configured correctly and printing works (as it did in any case before the driver re-installation). However, the scanner list that is called up via the Samsung utility shows no network scanner any longer).

I am in a professional office environment where I used to scan all incoming mail documents over the network, so the fact that this has ceased to function with the upgrade to Lucid Lynx is a major issue for me.

Forgot to mention the MFP is Samsung CLX-3175FN.

[Rutger Hendriks (rutgerhendriks)]

I found part of the solution for the error
netdiscovery: relocation error: /lib/libnss_files.so.2: symbol __rawmemchr, version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference

I renamed the file /lib/libnss_files.so.2 like so:
cd /lib
mv libnss_files.so.2 libnss_files.so.2-64bit

and created a link to the 32-bit version:
cd /lib
ln -s ../lib32/libnss_files.so.2 .

Now I don't have a problem running the Samsung scanner.

I'm guessing I will have problems now with other programs that do require the 64-bit version of libnss_files.so.2
So probably someone can come up with a solution to simply use the 32bit version for /lib32 without remove the 64-bit version.

Please let us know!

[Antonio Batovanja (toni-toni)]

I have a 32-bit Lucid installation here.
My solution was to rename
/lib/libnss_files.so.2 and
/lib/tls/i686/cmov/libnss_files.so.2

Now I can use the scanner, but I do get one more error:
netdiscovery: relocation error: /lib/tls/i686/cmov/libresolv.so.2: symbol strlen, version GLIBC_2.0 not defined in file libc.so.6 with link time reference

Details follow:

(now I can actually see and use the scanner!!!)

[sk (yahs)]

This bug also affects me, below is the output when starting xsane from a terminal.

"netdiscovery: relocation error: /lib/tls/i686/cmov/libnss_files.so.2: symbol strcmp, version GLIBC_2.0 not defined in file libc.so.6 with link time reference"

I am using a 32-bit Lucid installation Ubuntu 10.04.1

Using the solution posted by Rutger Hendriks

I can use the scanner but xsane still shows an error message as follows:

"netdiscovery: relocation error: /lib/libnss_mdns4_minimal.so.2: symbol strcmp, version GLIBC_2.0 not defined in file libc.so.6 with link time reference"

The scanner shows with the correct IP address in the Samsung Configurator, simple-scan works as does scanning through OpenOffice and Picassa.

[Fabien Toral (malibug)]

Maybe that bug is caused by a static linking with the libc.

I find this bug report on the debian list : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=589143#10
The error appears in a same manner and the explanation seems to be clear.
(i've found it by reading this bug report : https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/574726)

So, could the binaires provided by Samsung or by tweedledee (http://www.bchemnet.com/suldr/) provide the needed libc version ??

This bug seems to affect many persons. The thread in the ubuntuforums has more than 50 pages !

[Wolf Geldmacher (wolf-womaro)]

As a workaround to get the scanner working on lucid (until Samsung gets around to fixing this): I found that performing the renaming game for the libnss_* libraries above and then casting the result into a replacement netdiscovery shell procedure, followed by restoring the (no longer needed) libnss_* libraries to their original state works fine for my (static!) configuration (CLX-3185FW)

i.e. (as root, after having installed the MFP software)
cd /opt/Samsung/mfp/bin
mv netdiscovery netdiscovery.orig
cd /lib
mkdir backup
mv libnss_* backup
cd /opt/Samsung/mfp/bin
./netdiscovery --all --scanner >/tmp/output

(In my case this resulted in:
# Network printers discovery utility
# Legend: ip: address slp: detected,ipp,lpr,raw_tcp snmp: detected,devtype,description
ip: 192.168.192.3 slp: 0,0,0,0 snmp: 0,0,0 dsc: "Samsung CLX-3180"
a8 00 43 10 53 61 6d 73 75 6e 67 20 53 61 6d 73
75 6e 67 20 43 4c 58 2d 33 31 38 30 20 53 65 72

00 00 05 05 19 00
# Total 1 scanners found, 5s elapsed
)

Edit /tmp/output to contain (replacing the text between '' by the output of the command above!):
#!/bin/sh
echo '# Network printers discovery utility'
echo '# Legend: ip: address slp: detected,ipp,lpr,raw_tcp snmp: detected,devtype,description'
echo 'ip: 192.168.192.3 slp: 0,0,0,0 snmp: 0,0,0 dsc: "Samsung CLX-3180"'
echo 'a8 00 43 10 53 61 6d 73 75 6e 67 20 53 61 6d 73'
echo '75 6e 67 20 43 4c 58 2d 33 31 38 30 20 53 65 72'
echo '69 65 73 20 19 33 86 2b 00 00 27 d8 00 00 41 a0'
echo '00 01 51 00 00 01 00 00 00 00 41 a0 00 00 36 d8'
echo '00 00 05 05 19 00'
echo '# Total 1 scanners found, 5s elapsed'

mv /tmp/output netdiscovery
chmod 755 netdiscovery
cd /lib
mv backup/* .
rmdir backup

YMMV.

[Wolf Geldmacher (wolf-womaro)]

Small error above: Need to call
./netdiscovery.orig --all --scanner >/tmp/output
as renaming has happened before. Sorry.

[SCX-3205W (scx-3205w)]

Thanks, Wolf! This works for the Samsung SCX-3205W too.

For users of the 3200 series without the network features: Sane supports the scanner device with the xerox_mfp backend. This requires to add the usb id (get it with lsusb) to "/etc/sane.d/xerox_mfp.conf" and "/lib/udev/rules.d/40-libsane.rules".

[Fabien Toral (malibug)]

Yeah! cool! :) This works for my CLX-3175N.

Thank you for this workaround, Wolf!
I hope it will hold on to the next libs and links updates. i was bored to remove my libnss_files.so.2 after the ubuntu update...

i will try to write to Samsung about this issue (even if i know that they don't care)

[Uqbar (uqbar)]

That trick is not working with my SCX4623F, which is attached to a USB port.
The netdiscovery output is actually empty, apart of the three commented lines.
Any further idea?

[Uqbar (uqbar)]

Instead, the USB-ID trick mentioned above worked fine (with xsane and skanlite) but at a maximum of 600DPI.

[Nicola Masarone (n-masarone)]

Yesterday was trying to execute the Wolf Geldmacher's comment (#12), but for an accident the solution was stopped in the middle, before the step that recovers libs from the backup folder. The result was that the PC was not able to reboot anymore, neither in normal boot nor in recovery mode. The only way to fix the problem was to use a live CD, to mount the hard-disk containing the malfunctioning Ubuntu and to move the libs using last commands from comment #12 :
cd /lib
mv backup/* .
After that the PC was able to reboot again !

[Uqbar (uqbar)]

Well, more than reporting on how to fix the workaround I would like to make prossure on people here in order to recompile those libraries with the needed stuff inside: http://www.gnu.org/software/hello/manual/gnulib/rawmemchr.html.
Then any workaround (and workaround's workaround) will be unneeded.

[daniel venema (d-venema)]

Today's update of my Lucid installation also updated the Samsung driver package: this also repaired network scanning for my CLX-3175FN. I never tried the workarounds mentioned above.
