libstdc++.so.5 installed but not found

[patmalcolm91]

After upgrading from jaunty to karmic beta, libstdc++5 was removed and is no longer in the repos. This library is needed for my printer driver (lexmark z515: followed these instructions). The printer worked fine in jaunty.

The problem in the install process is when I go to verify it's working with the z600 script, which returns:

./z600: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory

I've found the jaunty .deb package for libstdc++5 and installed it manually, but I still get the same message.

I know it's installed because ls -l /usr/lib | grep -i libstdc++ shows:

lrwxrwxrwx  1 root root       18 2009-10-04 22:12 libstdc++.so.5 -> libstdc++.so.5.0.7
-rw-r--rwx  1 root root   855856 2009-10-04 23:15 libstdc++.so.5.0.7
lrwxrwxrwx  1 root root       19 2009-10-04 17:19 libstdc++.so.6 -> libstdc++.so.6.0.13
-rw-r--r--  1 root root  1027760 2009-10-03 17:33 libstdc++.so.6.0.13

But, ldd z600 (z600 is the script to test whether the printer is installed correctly) shows:

	linux-gate.so.1 =>  (0xf7f40000)
	liblexprinter.so.0 => /usr/lib/liblexprinter.so.0 (0xf7f0a000)
	libstdc++.so.5 => not found
	libm.so.6 => /lib32/libm.so.6 (0xf7ee1000)
	libgcc_s.so.1 => /usr/lib32/libgcc_s.so.1 (0xf7eb5000)
	libc.so.6 => /lib32/libc.so.6 (0xf7d5d000)
	/lib/ld-linux.so.2 (0xf7f41000)

By the way, if it makes a difference, i'm on the 64-bit architecture and the driver packages are x86. this didn't make a difference in jaunty, but i don't know if it will in karmic.

Thanks in advance for any help.

I figured it out.

Since the driver is for 32-bit, it was looking for a 32-bit libstdc++.so.5, so I went to packages.ubuntu.com/jaunty and downloaded and extracted the libstdc++5 deb file and manually placed the so files in /usr/lib32/

Now everything works great.

Same issue here with IBM Lotus Domino Server.

Downloaded this package: http://packages.ubuntu.com/jaunty/i3...dc++5/download

and dropped the files into /usr/lib32 worked a treat!

Thanks.

I've tracked this problem out down to a change in ia32-libs. The package ia32-libs_2.7ubuntu6.1_amd64.deb has the 32-bit libstdc++.so.5 and the newer package ia32-libs_2.7ubuntu17_amd64.deb does NOT have it. Sounds like it is time to file a bug report...

EDIT: Looks like someone has already filed a bug report:

Bug #431091

I just installed this package and its very quick and just works without messing with anything else. Its for 32 bit machines.

http://packages.debian.org/lenny/i38...dc++5/download

For me, this was used to get the Google Web Toolkit local browser to work on Karmic.

Brilliant thanks, this worked perfectly for me for getting checkpoint snx (ssl network extender) working for me.

Thanks.

Copernicus1234 I wouldn't be comfortable installing 32-bit libs on an amd64 install, and also where possible choose the Ubuntu ones rather than debian's versions - see the better link to Ubuntu's package above.

Note that deb packages can be extracted by by typing this command in a shell:

dpkg-deb --extract <deb> <directory>

This may help, http://www.digitalenigma.net/directo...gid=2009111000. It's a little tutorial I posted on my website.

Thats great, however i would recommend people dont get into the habit of installing 32-bit packages on 64-bit systems with "dpkg --force-architecture". You'll clobber something one day.

Given your instructions say to move the installed libs anyway, extract the files manually with "dpkg-deb --extract <deb> <temp directory>" and move them from there.

Here is something that was just posted into the bug listed above:

The nicest solution I found is adding this PPA: https://launchpad.net/~jason-scheunemann/+archive/ppa to your sources with these lines:
deb http://ppa.launchpad.net/jason-scheunemann/ppa/ubuntu karmic main
deb-src http://ppa.launchpad.net/jason-scheunemann/ppa/ubuntu karmic main

Accepting the key, and installing "lib32stdc++5" package. This is for amd64 systems.

Also, the following should serve as a quick way to add his ppa key to your local keyring:

wget -q 'http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x932062C9CD30EE56' -O - | sudo apt-key add -
