Zaurus - pdaXrom / Dosbox On Zaurus :)

« on: October 07, 2005, 09:59:48 pm »

Ok. I can't get 0.63 to work (libasound.so.2 missing. )

and pressing Fn still generates '1s' .. so how do you compile it yourself? anyone have the alignment patch for .63 ?

This is what needs to be done for the '1s' fix
replace the following lines in src/gui/sdlmain.cpp
/* Special Keys */
default:
code=KBD_1;
LOG(LOG_KEYBOARD,LOG_ERROR)("Unhandled SDL keysym %d"...
break;
/* change KBD_1 to something like KBD_leftshift */
/* or change 313 to just skip and go on? */

I will try to compile dosbox myself, I guess, but I have no idea what to do about the alignment patch and I haven't had great success doing that in the past.

Sharp ROMs / Cacko Gcc / Cramfs Development Image

« on: February 20, 2005, 11:54:41 pm »

Ah, well.. I'll look forward to that.

In the mean time I noticed -Dmain=SDL_main in the compile options. It occured to me the particular error I was getting was probably due to C++ style function encoding.

I edited src/gui/sdlmain.cpp and changed int main( ...   to extern "C" int main( ...  and got it to compile. Still doesn't work though

Something about not being able to find pthread in libSDL .. oh well.. I'll shelf it for now.. I'll be patient.

I might try to get GCC 3.3 working, in the mean time.

If I get SDL working, I will have dosbox compiled for Cacko/Z. I got it working on pdaXrom.  Any interest in adding that to the feed?

Sharp ROMs / Cacko Gcc / Cramfs Development Image

« on: February 20, 2005, 12:22:42 pm »

Hello! I have been using GCC 2.95 to compile stuff on Cacko 1.22a. So far so good. However, I need the static versions of, for example, libSDL 1.2.0 included with Cacko, and I was wondering if anyone packaged the development stuff (headers, libraries, etc) into a cramfs image (or something similar) .. and if so, where to download?

I have searched the forums and found stuff for GCC 3.3.x, but I think that development image is packaged for pdaXrom and doesn't really work for Cacko. Something like this for Cacko would make developers' and porters' jobs a lot easier.

I'm not talking about just the compiler-- that part is easy. I mean the static versions of libraries like libSDL, include files, etc. that are included in the distribution.

If cross-compiling on another machine is the prefered choice for development instead of native-- I haven't done that with the Z before. Anyone have a quickstart guide? Are there images to download for this purpose? Thanks.


P.s. For example, I've moved onto a program that requires libSDL. I was able to download the libSDL 1.2.7 image, but it seems the 1.2.0 included with Cacko has had a lot of changes for the C860 (changes that make it actually work right all of the time). Compiling generates a couple of errors.. undefined reference to `SDL_main'  /   relocation truncated to fit: R_ARM_PC24 SDL_main

Thanks

Software / HowTo: QEMU

« on: October 27, 2004, 08:27:12 am »

I'm successfully use QEMU to run Linux native console applications on Z. There are a lot of nice programs not ported for arm still ...

Just yesterday I have used sfdisk to re-partitioning SD card.

I'm not shure QEMU could work in other, than "user mode" on arm.

suruaZ

Did you compile it natively? What version of the compiler did you use / what version of QEMU?

I would like to document that, even if it is just usermode i386 binaries. It is a start.

Software / HowTo: QEMU

« on: October 26, 2004, 06:22:41 pm »

I'm on the qemu dev list... but I haven't been following it closely.
Last time I was paying attention, it was said that no one was working on
arm support (ie: run on arm, not x86 emulating arm, which seems to work fine).

If there is enough interest, I will work on it. The last time I had to do something similar, I developed a linux kernel driver for the 2.0 / 2.2 series of kernels.

There were a hand full of people on this forum that seemed to get it to work, and work well, but the links in those messages aren't there anymore. No documentation!!! ARG. heh.

So, let me know.

Software / HowTo: QEMU

« on: October 25, 2004, 11:17:32 pm »

Hello! I am working on getting QEMU (to run DOS apps) to actually work well on my C860. Is anyone out there actually doing this with success? I want to get VGA640x480 working with Cacko, and I don't mind putting together an unofficial how-to for others., as this seems to come up a lot.

I have bochs working, except there seems to be a slight libSDL problem... I haven't worked it out yet. it is just painfully slow.

The few folks that seem to have been able to do this, and post their information here seem to have fallen off the edge of the internet. The few binaries I can find of qemu are horribly out of date or broken.

Attempting to compile myself (simply changing the arcitecture in the ./configure file failed sort of badly).

I am also interesting in putting together a -nice- how-to for cross-compiling apps with a Debian host system and/or distcc for those builds that have to be done 'locally' on the zaurus. (Of particular interest to me is XMaxima, which I haven't got to work yet at all!)

Does anyone have any setups they'd care to share that I can put in the how-to for others?? Hopefully, this would get posted on ZUG permanently in some sane way so we stop two things: we stop getting people that ask the same questions every couple months and we stop the binaries from disappearing due to bitrot or disorganization.

Pari/GP is just a text interface

Try a search for Xcas, which is an X11 front-end. There are binaries (for the iPAQ) which work fine on my 5500 and C750.

Maxima is almost great. I'd like to have an easy-to-use front-end for it though. Is there any chance the X version of maxima will work with Cacko?

Texmacs? I couldn't get it to compile though.

Both of the above will/would require the use of XQt as you're using Cacko.


Simon

Thanks. I got Xcas working with Xqt. Is it supposed to take 20-30 seconds to start up, though???  I wish pdaXrom were farther along...  it seems so fast. I wouldn't think X could possibly be that light and fast.

I will play with it and post the results. This is more toward what I have been looking for.  (Eventually, I want a tricorder instead of a PDA. heh).

Someone here had maple or mathematica working on their Z. I can't seem to get to the sites mentioned in those threads anymore.

In the Zaurus Software Index you will find various options, such as Maxima, Pari/GP and YACAS.

Felipe

Maxima is almost great. I'd like to have an easy-to-use front-end for it though.  Is there any chance the X version of maxima will work with Cacko? I tried pdaXrom and wow, its fast, but it kind of put me off because all the applications I got used to were gone.

I also liked the application keys.. actually launching applications. (I know I know xmod map, but sheesh).

YACAS isn't far enough along, and Pari/GP is just a text interface.

On the old HP200LX, I could put in an equation and then solve it several different times (even with derive you can do that, but not as easily). E.g. I could type in x^3 + y^2 + z = q ... save it and then type in a number and hit an F-key that corresponded with one of the unknowns. For physics equations, I could put in different numbers for each run of an experiment and record that on a spreadsheet.

I have been using Hancom sheet to calculate some stuff like this, but it is a bit more painful than on the 200lx because I have to really simplify the equation to get it to work on the spreadsheet. (yuck).

Maxima with X's front end would cover the Derive end of the world, but I'm still looking for a good solver. QPlot seems like it is kinda getting there, but nothing fancy so far.

Oh, and setting bochs and qemu have been a real bust. The sites mentioned in other threads here are completely down and have been down for the past few days.

I carried for a long time an HP 200LX palmtop (runs DOS). I used and loved two apps on it: Derive, a math program, and the equation solver built-in to the 200LX calculator app. Derive wasn't really easy to use as an equation solver / general purpose calculator, but otherwise it rocks.

I am exploring the possiblity of using a dos emulator on a C860 with derive. Seems clunky though.

I want something like the equation solver that was built into the 200LX, and it would be fantastic if it were also about as functional as Derive (think of Derive as a sort of precursor to Mathematica).

Basically, I'm thinking there HAS to be a killer math app out there for this. I'd rather not use the TI or HP48 emulator that is floating around.  

I have been using the spread sheet app for some physics experiments.. I actually record the data and do the calculations right there (and boy that is every grad student's dream!).

What is out there? What do people want? Is there an X/QT app anyone would like ported to the Arm? I used the 200lx for the better part of 10 years with derive.. so this is an important project for me!!
