For Sale / Wanted / Wanted: Clamshell Zaurus, At Least With Working Display

« on: April 12, 2012, 11:14:43 am »

Hello,

Since I dropped my C760 some days ago and now its display is broken, I'm looking for a replacement:

a. A clamshell Zaurus with the display in good condition, the rest is irrelevant,

and/or

b. A C760 or newer in good condition, preferrably a C3100. Should have a good battery, and possibly a USB host cable for a C1000+, other accessories are not that important.

I'm in Germany, so in/near that is probably perferrable regarding shipping costs.

The file is there, what do I do?

Keep the java stuff in its .jar file, and add that to the classpath.

Microemulator might be a better way of running J2ME apps.

... if you're using a new enough jvm, which that of the Zaurus isn't.

In my experiments, I used j2me-zaurus_1.1.8_arm.ipk, ran it like "cvm -Djava.class.path=me2se.jar:opera-mini.6.5.jar ...MIDletRunner Browser" which gave a window (presumably from me2se, but then still didn't like the java stuff available.

Perhaps zaurus is more picky,
have to try that, thanks.

Reportedly the Zaurus is very picky regarding its input voltage.

The driver homepage says "SDHC up to 32 GB", so it should work.

SDXC seems to be the same hardwarewise, but I guess the driver needs to be modified for the higher capacity, and the Zaurus doesn't know the default exFAT filesystem on those.

I'm also one of the "hit View New Posts daily" people, don't usually have anything to write about though.

Anonymous visitors are often search engine bots, not real people.

Edit: Looking at the active users over the last days, most of those are newly registered and "validating" and have names like spambots.

Qt/Qtopia / Building A Gcc 4.5 Cross-compiler For The Sharp Rom?

« on: July 10, 2010, 12:07:00 pm »

I'm sorry to be a sceptic still but how do you gain the benefit of link time optimisation if you are linking with the old 2.95 ?

Heh, good question actually. From what I read, it works for dynamic libraries. I thought to do the same for static libraries, but that seems not possible. Anyway, that's not the only thing I hope gcc 4.5 is better with, it also should have a generally better optimizer, and support for the Xscale architecture.

Are you really sure you linked gcc 4.1 object files to 2.95 programs ? GCC changed the ABI around ~3.0.

The C++ ABI, yes. But the C ABI has been the same for ages, afaik.

Maybe if you used a pure C interface and rentrant code, but C++ I'm very sceptical.

Well, I tried something like

Code: [Select]

file1.c:
int test(int i) {
        return i * i;
}

Code: [Select]

file2.cpp:
extern "C" {
  int test(int);
}

void main(void) {
        cout << " x " << test(3) << " y " << endl;
}

Code: [Select]

gcc-4.1 -c file1.c
g++-2.95 -c file2.cpp
g++-2.95 -o test file1.o file2.owhich works as expected.

Is that a Sharp specific IM or is it available through Opie ?

It's one of the Sharp ROM's default Japanese input methods, only available in binary form. It might work on OPIE if that's compiled with g++ 2.95 (for the old ABI), but afaik all OPIE systems use newer toolchains.

I'm no expert but you can't mix files that use a different ABI, you need a libc for each ABI.

On a Debian etch system (the last one with gcc-2.95), I can link gcc 4.1 object files into g++ 2.95 C++ programs, so basically it should work. The question is, does that work for the Zaurus as well, and if yes, how do I get a compiler for it?

You can run zbedic on zubuntu and use scim with the tomoe module http://scim-imengine.sourceforge.jp/hiki.cgi?SCIMTomoe

The engine used in Kanji Nirvana was a simple port from somewhere else, so you could even take that to write your own input method.

Last time I looked into alternatives (unfortunately, I only have one Zaurus that needs to work, so I'm not very inclined to experiment with reflashing it), those all were pretty basic, requiring kanji to be input one by one, with each stroke separately in the right order. While the Sharp ROM gives me a screen-wide area where I can write whole words, and as long as the stroke order is mostly correct, it recognizes almost everything.

I think the majority of people use the tool chains that are already available.

Sure, that's easier. I vaguely remember people playing with gcc 3.x for the Sharp ROM years ago though, but I couldn't find any docs about this now.

I think the main reason why people don't try to build a more up to date gcc is to do with setting up a two libc system.

Hm, does that mean if I get gcc 4.5 to work, I can't link g++ 2.95 and gcc 4.5 object files (either directly or as dynamic libraries)? That was really the main point of this, if I can use gcc 4.5 only for pure C programs (or maybe C++ programs that don't depend on anything already on the Sharp ROM), it's not worth the effort.

Another reason is that they are not interested in such old kernels when you can go for another distro, e.g. Debian or zubuntu and immediately switch to a 2.6 kernel.

Yeah, but my main use for the Zaurus is still as a dictionary with Kanji handwriting recognition, so I'm stuck with the Sharp ROM.

Since gcc 2.95 is getting a bit old, and 4.5 has interesting new things like whole program link time optimization, I've though about building a gcc 4.5 cross-compiler to complement g++ 2.95 (which can't be replaced because of the ABI). The problem is, there doesn't seem to be much documentation about how to actually build a cross-compiler for the Zaurus (maybe there was more five years ago). Has anyone every tried this (probably not with 4.5, but maybe some older version)? Are there any docs on how to build any cross-compiler for the Sharp ROM, or have people always just used the premade packages?

The original Sharp ROM obviously. As far as I know, there is no archive that contains all files, but maybe someone can upload the original module here (if the new driver is installed, there's a backup copy in /opt/QtPalmtop/share/sdhc-driver/). Otherwise you need to do the backup - reflash - grab module - restore cycle.

It looks like the SD module Cacko uses for the cxx0s is not the same as the original Sharp ROM. The needed module is /lib/modules/2.4.18-rmk7-pxa3-embedix/kernel/drivers/block/sharp_mmcsd_m.o with an md5sum of b6a026d0e0eaba101a3746bc0555cdf5.

No, that's the message when the installed SD module isn't the one the package needs.
