kvncviewer - next iteration of kindlevncviewer

[MoyoWa]

Greetings @langelgjm,

I am having the same problem (GLIBC_2.7 not found) as I am trying to load this code on a Kindle DX. I do not have access to an environment where I can recompile according to the changes to the Makefile that you posted. Would it be possible for you to post the recompiled version that I can just copy onto the Kindle, please?

Thank you so much!

Same issue here. Has anyone got it confirmed working of the DX/DXG?

[hawhill]

OK, since I know how to work around it, I think I might be able to do a version compiled for the older devices soon (TM). Meaning in 7-10 days, I think. Up to then, I won't have much time at hand.

@Hawhill, great! If u need some testing I will happily support.

[hawhill]

Sorry I didn't get back earlier. Might take up to 10 more days. Not enough spare time at hands currently, I'm afraid.

@hawhill. Thanks for doing this work during your busy schedule. It's much appreciated and I look forward to the results. This is just what my wife needs to be able to keep up with email while recovering from a concussion. She can use an e-ink screen fine, but not a standard computer screen. Unfortunately, with the older Kindle DX I have, I wasn't able to get things working. Interesting to think of the medical benefit to be had from a cost-effective way to make e-ink monitors accessible. Thanks again.

[hawhill]

You could give this a try. Unfortunately, I can't really test it right now.

[Bobco]

I went through the process of making my older Kindle DX function as second monitor, and everything seemed to proceed smoothly till the very last step when I enter the command:

[root@kindle root]# /mnt/us/kindlevncviewer/kvncviewer.sh 192.168.2.1:1 &

Instead of the Kindle DX displaying the computer screen, I receive the response:

-sh: /mnt/us/kindlevncviewer/kvncviewer.sh: not found

I'm not very technically sophisticated on this process. Does anyone know what I may have done incorrectly?

[hawhill]

So you put all the files into the folder "kindlevncviewer" on the volume that presents when plugging in the Kindle via USB, right?

[Bobco]

I unzipped the file, and dragged the folder it contained "kvncviewer" into the root directory of the Kindle

[hawhill]

The path you use to call it would be /mnt/us/kvncviewer/kvncviewer.sh then.

[Bobco]

ah yes, that makes sense. I tried that but still got the error, then realized that the zip file you sent must only include the updated files and not all the files (since kvncviewer.sh does not appear to be in there, along with some other files and folders that are in the older version). So I merged those into the older version of kvncviewer (replacing files with same names) and tried again, but now get this error:

[root@kindle root]# Failed to set value <0x3>
./luajit: cannot open vncviewer: No such file or directory
Failed to set value <0x3>

If it's helpful to know, there is a file in the root directory called "luajit", but no folder with that name. There is a folder with the name "luajit-2.0" though.

Thanks again, I do appreciate your patience with me being a command line neophyte trying to get this working.

[hawhill]

Oh, I think I made an error when packaging the software. Wait a second, I'll upload another updated version to this post soon.

Edit: No, it was "right". The wrapper script is an old one. This software isn't quite polished. On the command line, try to do as follows:

cd /mnt/us/kvncviewer
./luajit vncviewer.lua 192.168.2.1:1

By the way - did you try to simply use the old variant linked in the first post?

[Bobco]

Thanks again, but still no luck. I did try the old variant, but still got the same error I described in the first post. Then I went back again and merged the old variant with the new one you posted (putting it all in the folder "kindlevncviewer"). I tried the commands (first trying the original commands I used, then trying the new one you posted). This time I got a series of messages, but nothing on the kindle dx. Here is a copy of how my telnet session went, in case that helps explain anything ...

OK, that output looks good. Sort of. It shows a bug in the code - so I will have to get back to the editor and fix it. Sorry for the small steps, but I simply don't have a device to actually test. Will get back as soon as I had a chance to fix it.
