[gentoo-user] ncurses is gone

[gentoo-user] ncurses is gone

[Alan E. Davis]

Ncurses has disappeared, and the system is dead.  I think it is
unrecoverable.  I had hoped to use a binary package, but for now,
since I shut the machine down, it will not boot.

Is this hopeless?  It happened during an emerge -uDvNa world

What are the errors or other relevant output to the console?

It's never hopeless unless the hard disk is damaged, e.g. from a
head crash or similar catastrophe.  The important thing is to avoid
trying random things without knowing what you're doing. You can
turn a simple recovery into a hopeless mess that way.

I find that I can usually get myself out of a 'hopeless' mess just
by downloading a live gentoo boot CD and using that to install a
recent gentoo snapshot.  You need a second (working) computer to
do that, of course.  (Everyone should have as many computers as
possible for exactly that reason :o)

Meanwhile, more info would help, as the others have already said.

thank you.  And your comment was duly noted about trying random things.

When I boot the system, the following message follows (after one other
line) after INIT: version 2.86 booting

/sbin/rc: error while loading shared libraries: libncurses.so.5:
cannot open shared object file: No such file or directory.

Use a live-linux from usb-stick or CD, mount your root, chroot into it
and give revdep-rebuild a try. That should help.

I think you are telling me to use Gentoo Live CD specifically, and
mount my installed "/" (on /mnt/gentoo?), chroot into it (as described
in the install docs) and run revdeb-rebuild.

Is revdep-rebuild part of the live cd?

I'll try it.  Thank you VERY much.  I have installed Ubuntu, but these
steps will save my having to deal with that.

It doesn't matter. Once you have chrooted you are using software
installed in the chroot. 

However, it may not be possible to use revdep-rebuild without ncurses, in
which case you need some kind soul with a similar setup to provide you
with a binary package of ncurses, which you can unpack into your root
directory.

This is exactly what happened.  I used the systemrescuecd, chrooted,
and, lo and behold, the same error message was coming up.  What I
might be able to do is symlink to libncursesw ?  Don't know whether
it's even on the system.

On the other hand, with a binary ncurses, I could see that might work.
 Is there a binary repo?  (Back to sabayon?).  I suppose I need to
know the exact version.  Does it matter which use flags it was
compiled with?

Thank you!

Alan

I wonder if you say  -C and -P would it still use ncurses since you
are turning off color and progress indications?

As I type, the system is booting, after untarring a Sabayon package of
ncurses into the / partition, mounted in a parallel ubuntu setup.

The system has booted, and I am typing this message from it.

Thank you everyone.

Might you just be missing a symlink?  I have the following on my system:

lrwxrwxrwx ... /lib/libncurses.so -> libncurses.so.5  
lrwxrwxrwx ... /lib/libncurses.so.5 -> libncurses.so.5.6   
-rwxr-xr-x ... /lib/libncurses.so.5.6

HTH,

David

Now you need to emerge the proper Gentoo package to get your database
consistent with what is installed.

Yes.  It's working.  It emerged without complaint.

Thank you for the useful advice.  I am very pleased that this system
is working now.
