Late (from me) but good: Thank you Keef! Very Happy
There was an interesting comment in response to the link you posted on libtinfo:

The lack of libtinfo.so is not so much a specific Ubuntu oddity, some other distributions don’t provide it either. The default behaviour when building NCurses is not to produce a separate libtinfo.so. It is only done when adding the –with-termlib switch to the NCurses configure script when building NCurses.

I do agree that linking libtinfo.so explicitly is broken behaviour, as it will not exist with a default shared library build of NCurses.

The same issue can arise with libtic.so, which can also be built as a separate library from libncurses.so by use of the –with-ticlib switch.


musher0, it may be something to remember if ncurses is used in later versions of puppy, a recompile will solve the problem(s). I have run into the problem before, but I cannot recall which program that refused to open.

This is the important bit:
Code:
cd /usr/lib
ln -s libncurses.so.5 libtinfo.so.5
ln -s libtinfo.so.5 libtinfo.so

When browsing my /lib and /usr/lib in my LupuPlus 5.2.8_005-1., I discovered something very odd.

In my /lib:
libncurses.so.5 -> libncurses.so.5.7

In my /usr/lib:
libncurses.so -> /lib/libncurses.so.5
libncurses.so.5 -> libtermcap.so What the h...??
and then
libtermcap.so -> libncurses.so More what the h...??
So I made symlinks in /lib and /usr/lib:
Code:
cd /lib
ln -s libncurses.so.5.7 libtinfo.so.5
cd /usr/lib
ln -s /lib/libncurses.so.5.7 libtinfo.so.5

It works! Now I have to find out what the mysterious libtermcap.so link is intended for! I have installed lynx, xpdf and pdftk, and I suspect one of them needed that link.

Finally my old $LESS:
Code:
export LESS='-Ij20Wsz-5M'

You have to check out the option list for that one! Very Happy

EDIT: If you install the companion .pet, right-clicking on a bin-file let you choose view-with-less.sh, which open the text in a urxvt window. The problem is that you get the question: This file seem to be a bin file, open anyway? If yes, lots of unreadable code! If you open a terminal instead and write less /bin/somefile, it open as a normal readable file would do. Something is wrong here, musher0.

Hello, Tallboy.

I don't have the problem you mention viewing executables. For ex. I have attached a
picture of less "viewing" the wmx executable, with a search for the word "menu".

When less loaded it, there was a line at top saying "==append to filename" and some
other words, and then less picked up the ASCII characters (but not the machine code)
in the file and displayed them. I don't think there is anything wrong. I use that feature
sometimes to see if there are some undocumented commands in an executable.

The only other executable "viewer" I know in Linux is joe ("joe's own editor"), which has
a hex mode. (But I don't have lots of experience with hex editors.)

There is also a hook for less to see "odt" files, and there you will see "garbage" mixed in
with other information, such as word count or paragraph count. Yeah it's not pretty to
look at, but it does not bite ! Smile

Again, I find this helpful when I want to refresh my memory about word count and such.
Using less is instantaneous, no need to wait for OpenOffice to load. You type "/" and the
word "count", and you soon know !

As to the extra libraries, I had similar surprises as you had, but I'll have to back-track
what I did. Keef's short message was extremely helpful in this.

If I remember correctly, I cleaned up the libs. I believe I had ncurses-blabla-
so-version in /lib and /usr/lib, which is unnecessary. Only one copy is necessary, of
course.

Hi, Puppyists.

I believe this could be another interesting tool in the less toolbox:
http://murga-linux.com/puppy/viewtopic.php?p=815375&sort=lastpost#815375
It's for viewing pdf files in plain text format. It uses pdftotext and less. Might be useful
for taking a quick glance at what a pdf is about. I find it a little faster than epdfview, if
I may say so.

BFN.

The new less-470 has been out for a few months now, so here you go! Smile Enjoy! Smile
less-470.pet
Description  Should be a drop-in replacement for any of the earlier versions above. The "view-with-less"
script works fine with it, at least on this Slacko-6.0b Puppy.

Hello, people!

I've uploaded a new less script to follow errors while developing scripts or configuring at:
http://murga-linux.com/puppy/viewtopic.php?p=821855&sort=lastpost#821855

Enjoy!

I'm on Fatdog64 most of the time, so I can't use your pets, but - as a long-time less fan - I still want to thank you for your less posts!

Hi, step.

Can't you? Have you tried? Sixty-four-bit machines are advertised as being able to
run 32-bit programs without a sweat, are they not ? Shocked

And thanks for the thanks, of course! My pleasure! Smile

No I haven't tried yours. Fatdog64 already includes less, albeit an older version. The thing is that I've been nailed on Windows for a few days, and will continue to be so for awhile. I don't get enough play time on my fav linux desktop. Sad
