Terminal emulator for Touch (and Paperwhite?)

libpng16 **should** support all of the symbols of libpng12

The easiest way is to try it.

Go to the directory that has libpng12 -
Enter the command:

ln -s libpng16 libpng12

Then try Kterm again.

The symbols in ELF libraries are versioned, the dynamic loader can figure out the correct entry points.

- - - -

Otherwise, you'll have to download the earlier firmware version from Amazon -
Then use KindleTool to unpack the update, find libpng12, and move it to the same place on the Kindle that holds libpng16.

Note:
You shouldn't have to diddle LD_LIBRARY_PATH any more than it already gets diddled in either case.

Unless you simply want to keep the "mntroot rw && add_random_stuff && mntoroot ro" to a minimum.
But it could be safely assumed a symlink is not going to fill up the empty space on the system partition.

Thought I'd mention it anyway.

Thanks, knc1 and eachwartz. I appreciate your help. Unfortunately I haven't been able to find the directory containing libpng12. I found libpng.so and libpng16.so in /usr/lib but not libpng12. Thoughts?

[eschwartz]

There is no libpng12.so -- create it, as a link to libpng16.so

cd /usr/lib
mntroot rw && ln -s libpng.16.so libpng.12.so && mntroot ro

As user 'root' -

mntroot rw
cd /usr/lib
ln -s libpng16.so libpng12.so
mntroot ro

Then restart the machine

I tried this but it kterm still won't run so I probably did something wrong.

Thank you, knc1 and eschwartz, for trying to help. Kterm is not something I used very often so I'll wait to see if someone else is able to get it to work.

hmm...
libpng16.so might not be the file,
So just do:

cd /usr/lib
ls -l libpng*

(that is dash-ell, not dash-one)

then post the result here.
it will be small enough to in-line here, inside of a code - /code pair of tags.
You will see an example of the tags when quote this message.

PW2 with 5.6.5:

lrwxrwxrwx 1 root root 11 Aug 1 00:53 /usr/lib/libpng.so -> libpng16.so
lrwxrwxrwx 1 root root 19 Aug 1 00:53 /usr/lib/libpng16.so -> libpng16.so.16.15.0
lrwxrwxrwx 1 root root 19 Aug 1 00:53 /usr/lib/libpng16.so.16 -> libpng16.so.16.15.0
-rwxr-xr-x 1 root root 158032 Aug 1 00:50 /usr/lib/libpng16.so.16.15.0

I tried binary patching matchbox keyboard to use libpng16.so, and got the following instead:

/mnt/us/extensions/kterm/bin/matchbox-keyboard: /usr/lib/libpng16.so: version `PNG12_0' not found (required by /mnt/us/extensions/kterm/bin/matchbox-keyboard)

More binary patching just produces:

/mnt/us/extensions/kterm/bin/matchbox-keyboard: /usr/lib/libpng16.so: version `PNG16_0' not found (required by /mnt/us/extensions/kterm/bin/matchbox-keyboard)

My process:

mv matchbox-keyboard matchbox-keyboard.libpng12
cat matchbox-keyboard.libpng12 | sed -e 's/png12/png16/' -e 's/PNG12/PNG16/' > matchbox-keyboard
dd if=/dev/zero of=matchbox-keyboard bs=1 count=2 seek=4496 conv=notrunc
diff <(hd matchbox-keyboard.libpng12) <(hd matchbox-keyboard)

I've worked out a solution here: https://www.mobileread.com/forums/sho...=1#post3159397

I accidentally stumbled upon this thread. It seems I stopped receiving mobileread notifications. You could have attracted my attention through issues on kterm github page.
From the thread I gather that the problem is related to matchbox-keyboard, because it links to libpng. Kterm itself should not be affected.

I rebuilt matchbox-keyboard with libpng16. I hope it will solve the problem (unless I spoilt something else). Maybe someone could test the new binary. If it is ok, I could make new package for kterm.

Greetings to all!

UPDATE: New tested package for firmware 5.6.5 and above is on the kterm page.

The most actively maintained matchbox-keyboard seems to be here:
https://github.com/xlab/matchbox-keyboard
Which had the libpng related updates done about 2 months ago.

I doubt any of the newer versions of matchbox-keyboard would work on Kindle out of a box. Last time I played with it all newer versions were crashing, so I ended up patching some ancient release. Maybe more chances with the new firmware (?) but I don't have a supported device to test it.

Did you try the recompiled version from the previous post?

[knc1]

I just didn't see any reference to matchbox-keyboard your using at the github repo you posted.
Other than the matchbox-keyboard patch in your tree.

Since there are a lot of matchbox-keyboard forks lose, maybe mentioning which one you are using would be helpful.
Even better, a link to the actual repo you are using for mbk.

Keyboard used in kterm is matchbox-keyboard_0.1+svn20080916.
