Best of the Newsgroups: broken shared libraries

Main Index

Shared libraries save space, give predictability to applications and all that, but when important libraries break or go missing, a lot of stuff instantly stops working.

First off, what version of bzuip2 are you using? there are several binaries 
floating around by now.
One of them comes in gwxlibs or gnutools from SCO now so I like to try to 
always use that.
find out like this:
# which bzip2
/usr/bin/bzip2

Then find out details of it's pedigree and what libs it needs:
# ls -l /usr/bin/bzip2
lrwxrwxrwx   1 root     sys           40 Nov 20 19:04 /usr/bin/bzip2 -> 
/opt/K/SCO/gwxlibs/2.1.0Ba/usr/bin/bzip2

So on my box, the bzip2 that will run when I just type "bzip2" comes from 
gwxlibs-2.1.0Ba (part of osr507mp4 but seperately installable on 5.0.6)
(Being able to do this has to be one of the very few desireable aspects of 
the whole symlink-the-world scheme sco uses)

Now see what libraries it wants to load at run-time:
# ldd /usr/bin/bzip2
/usr/bin/bzip2 needs:
        /usr/lib/libbz2.so.1
        /usr/lib/libc.so.1

Now look at those libraries on a working box:
# ls -l /usr/lib/libbz2.so.1
lrwxrwxrwx   1 root     sys           46 Nov 20 19:04 
/usr/lib/libbz2.so.1 -> /opt/K/SCO/gwxlibs/2.1.0Ba/usr/lib/libbz2.so.1
(well that only makes sense that lib bz2 came from the same package that 
supplied the bzip2 executable)

# ls -l /usr/lib/libc.so.1
lrwxrwxrwx   1 root     root          41 Mar  1  2005 /usr/lib/libc.so.1 -> 
/opt/K/SCO/Unix/5.0.6Ga/usr/lib/libc.so.1

Not so helpful. I don't know offhand how you'd detect that your libc was 
wrong without another working box to look at in this case.
I do know that it's safe and reasonable to simply see that your non-working 
binary comes from "gwxlibs-x.x.x" and go re-read the cover letter for that, 
and install anything it says are prerequisites even if you think they're 
already in.
Just reinstall oss646c. Or maybe uninstall-reinstall, but the uninstall will 
surely balk about breaking a slew of dependancies. As long as you know you 
are only re-installing immediately after, and as long as you already have 
the oss646c vols in hand and unzipped/untarred etc in case your 
wget/curl/gzip/bzip2/ssh etc don't work between the uninstall & reinstall, 
it's probably fine. I've done it before.

You say you have oss646c on 5.0.6
But you have:
-rw-r--r--   3 bin      bin       810208 Nov 23 14:14 /usr/lib/libc.a -> 
/opt/K/SCO/unixds/5.1.2A/usr/lib/libc.a
-rw-r--r--   6 bin      bin       593700 Nov 23 14:14 /usr/lib/libc.so -> 
/opt/K/SCO/unixds/5.1.2A/usr/lib/libc.so
-r-xr-xr-x   1 bin      bin       372160 Nov 23 14:13 /usr/lib/libc.so.1 -> 
/opt/K/SCO/Unix/5.0.6Ga/usr/lib/libc.so.1

While my 5.0.6 with oss646c has: (using the same "l -Wv" comand it's 
important to note)
-rw-r--r--   3 bin      bin       927924 Nov 21  2004 /usr/lib/libc.a -> 
/opt/K/SCO/unixds/5.1.2A/usr/lib/libc.a
-rw-r--r--   6 bin      bin       594532 Nov 21  2004 /usr/lib/libc.so -> 
/opt/K/SCO/unixds/5.1.2A/usr/lib/libc.so
-r-xr-xr-x   1 bin      bin       562076 Nov 21  2004 /usr/lib/libc.so.1 -> 
/opt/K/SCO/Unix/5.0.6Ga/usr/lib/libc.so.1


I'd just install oss646c and then any of the at least 3 newer gwxlibs since 
the 1.3.2Ag you have installed currently.

You can install the gwxlibs as a sub-component of osr507mp4 even on 506 (I 
did it) but it's kind of messy and I don't recommend it. I did it because 
the osr507mp4 tar file was available before the suppcd iso image.
But now, a 5.0.6-friendly copy of gwxlibs-2.1.0 is on the osr507suppcd4.
You don't need to burn it to a cd either. You can download and mount as a 
ramdisk and install packages from it without burning a cd like this:
There are actually two different sets of packages on the suppcd and it takes 
different mothods to get at them.

To install from the main body of the cd, like when you pop a cd in and run 
custom and select install,  "from cd drive" you can do this:
cd /
wget 
ftp://ftp.sco.com/pub/openserver5/507/iso/osr507suppcd4/osr507suppcd4.iso
marry -a osr507suppcd4.iso
mv /dev/cd0 /dev/cd0.orig
mv /dev/rcd0 /dev/rcd0.orig
ln -s /dev/marry/osr507suppcd4.iso /dev/cd0
ln -s /dev/marry/osr507suppcd4.iso /dev/rcd0
custom
marry -d /dev/marry/osr507suppcd4.iso
mv -f /dev/cd0.orig /dev/cd0
mv -f /dev/rcd0.orig /dev/rcd0

That works for any custom install cd, like the main os install cd etc...


Then there are some additional simple directories with VOL files in them 
that are just like the various downloadable vol packages and they are 
simpler to get at and use.
Until SCO makes the new gwxlibs available conveniently as a seperate 
download, this is what you want to do:
cd /
wget 
ftp://ftp.sco.com/pub/openserver5/507/iso/osr507suppcd4/osr507suppcd4.iso
marry -a osr507suppcd4.iso
mount /dev/marry/osr507suppcd4.iso /mnt
custom
umount /mnt
marry -d /dev/marry/osr507suppcd4.iso

In this case, while in custom, you select install, from localhost, media 
images and type in one of these paths:
/mnt/506dev/apache
/mnt/506dev/gwxlibs
/mnt/506dev/openssh
/mnt/506dev/oss646c
/mnt/506dev/perl

lookitthat :) oss646c all nice and ready right there. I'd do oss646c, then 
gwxlibs, then everything else in no particular order except perl might need 
to come before apache.

Also, since your libc/gwxlibs is kind of messed up apparently, your wget may 
not be working either, or curl, so you may have to replace the nice one-line 
wget command with using plain ftp to manually get the iso file into your 
root directory.
