iLiad Text editor/WP on iLiad?

[Antartica]

Hi!

I've compiled AbiWord-2.4, but don't have my iliad at hand (no, it's not bricked, it's just that it's at home and when in home I literally don't have any time to mess with it), so I'll need cooperation:

Attached to this message is a tar.gz that contains the executable compiled for the iliad.

I need to know what are the needed dependencies.

1. copy the file to the iliad
2. uncompress the file with a
# tar -xvzf abiword24-iliad.tar.gz
3. do an ldd on the uncompressed file so that it lists the missing libraries:
# ldd ./AbiWord-2.4
4. Copy the result of that to a reply to this message :-)

Then, I'll pack another tar.gz with the missing libraries and someone will have to try again to see about what it complains (because I'm sure it will complain about missing files...).

P.S.: BTW, Scotty, this is going to be the test case of the modified libX11 with embedded calls to liberipc/liberdm... hopes up! If it works, there will be no need to port each new app we want in the iliad, just a recompilation will suffice.

[scotty1024]

Antartica, I know you think embedding the erdm in the X11 lib means the end of porting to the iLiad but ...

The Matchbox window manager needs special care in the code.
The popup keyboard needs to be enabled or auto popped up as needed.
The frenetic busy LED needs to be turned off if launched via [SHELL] hack.
The buttons need special handling in order to operate with them (pagebar, up button etc...)
And many of the apps I've worked with need a fair amount of rework to make them into unzip-n-go applications that don't need things installed to the root filesystem.
Plus if there is anything you can update on the iLiad with a higher brick factor than the X11 library... I don't want to meet it.

I'm testing your abiword.

By the way, you realize only you and I likely have ldd on our iLiad's right?

[scotty1024]

OK, forget ldd (turns out even I don't have it), here's the objdump -p output.

The frenetic busy LED needs to be turned off if launched via [SHELL] hack.

As I see it:
- For "full screen apps", there is no need to make the main window a popup. I want them to be as big as they can (hey, at home I'm using ratpoison window manager in the htpc because it does exactly that; it's nice for low resolution displays -- the TV definitely is a low resolution display, the iliad also qualifies not because the resolution but because the size...)

- The popup keyboard and the busy LED only need to be enabled once, at application startup, so this is done one at libX11 startup :-).

- I agree that this is a problem. I would like a more general aproach, so as to map them to sane keys (I've not resolved the problem of how -- yet; perhaps with a helper application...):

up-button: keypad-up
down-button: keypad-down
select-button: enter
flipbar-advance: space
flipbar-backwards: backspace
return-to-previous-menu: escape
main-menu: (I don't know-- I would like this key to open the contents in books, and to open the menus in applications, but I think that there isn't a standard binding for that)

sed is your friend here :-) (after compiling the app, you can change strings of paths to another strings, if you don't change the length of said strings -- coupled with the unix permissivity of double-slashes for directories, you can use shorter path strings, too).

I agree, but only if it's installed in root.

But I don't want to install the patched libX11 in the root filesystem, but in the local libs directory of each app (so the brick factor is null).

Thanks :-)

Ups! I forgot that...

In reality ldd for elf executables is just a helper script, that calls the binary with a special environment variable set (LD_TRACE_LOADED_OBJECTS=1).

So, if you can post the output of

# LD_TRACE_LOADED_OBJECTS=1 ./AbiWord-2.4

I would very grateful.

P.S.: I attach the ldd script. It's part of the generated tools when you build the crosscompiler using crosstool (search for ldd in the build directory). I hope that it works with the shell of the iliad, but I didn't tested it...

What do you think?

The author of TED is thrilled by the idea of bringing his baby to the iLiad.

[Matthijs]

About the keys: all iLiad hardkeys are mapped to normal keyboard keys.
The flipbar is PgUp and PgDn, the arrow up/down keys are Up and Down, the confirm key is Return, the UP key is Home. Long presses are different keys: F1 through F6.

You need to make sure the "xresname" in the registry is correct though, so in your program you would need to set that name to "sh" for use with the SHELL hack I guess. This is so contentLister can send the keys to your program.

Hope that helps. Please feel free to post questions like these on the iRex SW forum, they will be answered.

Thanks Matthijs. Nice to know. :-).

Ted is easy to compile. Here you have:
http://projects.mobileread.com/iliad...iad_0.1.tar.gz

Gotchas:
- The package doesn't have the manifest.xml nor the icon.
- I've not tested it yet. It uses the libX11 hack (untested, but it will not brick your iliad -- although having to reset it with the back-button is factible).
- The package is bigger than needed, some libs of the lib directory are redundant and could be deleted (but not libX11... or you 'll miss the autorefresh hack).By bigger than needed I mean: 9MB of package, 26MB of installed size.

Conclusion: if it works, great, if not... it's just a work in progress O:-).

P.S.: Anyone would like my current patch to libX11? Or is it better to wait to release it until it works?

Where is the patch in the tar ball...? I might be wrong, but the files all appear to be binary files...

[henkvdg]

I tried it, it does not work yet. I had to reset my iLiad.
It seems like it is starting up forever.

That was exactly my question, if someone wanted the patch in its current untested shape.

Here you have ;-)

Thank you very much.

I might have missed something . I'll review the code and hopefully generate a new version.

Stay tuned .

One of the things I'm trying to do is encourage people to publish diff scripts when they publish ported apps... It helps everyone if we can all see the tricks each of us use...!

[Riocaz]

may I suggest moving this to the Development area?

Antartica, another Xlib intercept for you... need to force the main window name. But of course that then changes the resource names.

Or perhaps you can change Xlib to report the name to iRex as "sh" and keep the original resource name for purposes of loading resources?
