taskwarrior (REQUIRES KTERM)

[theol0403]

Hello, I had the same problem. I forgot exactly what I did but what I have now has no problems. I will in a week add new parts to my tutorial but for now just google how to upgrade wheezy to jessie. Then you will have to recopy the versitile and intrid files, and then you will have the latest (stable) versions of things. Also I will put in my tutorial how to use qemu directly in windows to speed things up.

Here's the official Debian link for upgrading wheezy to jessie: https://www.debian.org/releases/jess...rading.en.html

Looks like as much work as building a jessie image from scratch!

I use qemu directly on ubuntu... no need for windows.

No, you only need to do this (change apt sources and upgrade):

https://www.howtoforge.com/tutorial/...table-release/

or

https://linuxconfig.org/how-to-upgra...stable-release

It just takes a bit of time.

theol0403,

I followed the steps given in the links and was able to upgrade my Debian-Wheezy-Armel VM to Jessie.
Took approx. 16 Hrs.
Thank you!

During login, either initially, or later by SSH, I get a series of ipv6 related error messages of the form:
ipv6: wrong symbol. Don't know how to fix this.
But am able to otherwise work on the VM.

Next, I was able build the latest version of taskwarrior on the jessie-armel image.
After the build was over, I found the required library file dependencies by using ldd.
Copied over the library files and the executable over to Kindle (PW1) and tried executing it.

But got a series of GLIBC version related error messages. Apparently, the version of GLIBC on the PW1 is not compatible with that on the Debian VM, which is what the build has used. Any help on this would be appreciated!

Maybe the latest version of taskwarrior is too complex for the Kindle porting. It seems to be using (as per the ldd report) some 20 library files, as compared to the 2 of the earlier ported version!

ldd IS NOT the answer to your problem.
I spent about 18 hours yesterday creating a write-up on how to deal with symbol errors.
If you can wait a few more days for me to finish the write-up, test it, and post it - then you will have an answer that works.

Of course, you are free to work it out on your own.
The lessons might stick with you better if you did it yourself.

I don't think so

[nasser]

Great!
Thanks, encol!
You're really filling the gap left by people like twobob and niluje!!
Will try it out..

[nasser]

encol,

I tested your build on my PW1...
Various missing library messages came up, which I eliminated progressively by copying the library files from my build on my Debian-armel-jessie VM.

However, I couldn't fix the last error: It's loading libc.so.6 from the PW1's /lib directory... instead of the libc.so.6 from your build's tasklib directory. Any way to force it to load from your directory??

<<?? Why is it still loading the Kindle(PW1)'s /lib/libc.so.6 instead of tasklib/libc.so.6??>>

Btw, your usage of "ld-linux" was very interesting for me! Didn't know that trick.
Live and learn!

Hi encol,

I tested again, this time on PW3 and it works!
Of course, I had to add some missing library files, but not as much as for PW1.
The error messages are also different in some cases or totally absent.

Test Output from PW3:

No matches.

Looks like it might work on KT3 too.. [EDIT 25-Jul-17: Tested on KT3. Works OK!]
But I would really like a solution for it to work on PW1!

The paperwhite has 2.12.1 installed on it.

That should not be the problem.

In addition to the notes above, I did not check for anything it might be dl opening.

PW-1, 5.6.1.1 has:
libstdc++.so.6.0.14
pre-installed
6 > 3 so that should be alright.

Strange behavior: on my PW3 i had to include in tasklib only those libraries in the package
What FW version fo you have on your PW3?

Try to grab needed libraries from your PW1 and copy them in tasklib folder, replacing existing ones

Sorry! I should've mentioned that my PW3 still has the "factory image" which is loaded by the jailbreaking procedure. I never updated it because it had some "goodies" not present in the "customer image"!

Will try. The issue seems like it's loading the libc.so.6 present in the /lib folder of the PW1, rather than the one in the tasklib directory. I'll copy the libc.so.6 of the PW1 into the tasklib directory and see what happens.

Use:
LD_DEBUG=libs task
to start the program and the loader will show you what the problem is.

There is a companion application to TaskWarrior called tasksh (Task Shell).
This is a front end wrapper to the main program. Now there is no need for prefixing every command with 'task'.

It also has a powerful "review" command which is not available in the main program. With this each individual task in the list can be reviewed with all details visible and also edited(vi is called).

I was able to build this on my debian-jessie-armel VM. I copied this over to my PW3 and it worked OK. I had to copy over 2 more libraries: libreadline and libtinfo. Also, this application expects the main program to be available in the same directory. For this, I added a export PATH command. I also dropped the 'ld-linux' method and used an export LD_LIBRARY_PATH command instead.

EDIT 25-Jul-17: Works OK on KT3 too! Needs the same libraries as in PW3.

The ports of both taskwarrior and this companion shell need some more work to make them a kindle user-ready package. There seems to be a differing set of library requirements depending on the kindle model and framework version.
