http://extcalc-linux.sourceforge.net/

Extcalc is a scientfic graphic calculator for Linux.
Extcalc is designed to use the full performance of a modern Computer for mathematical calculations.

Here are the main qualities:

* Calculating all standard mathematical operations on a Qt-based interface
* Usage of special functions like integration and differentiation
* Drawing different types of 2D- and 3D-graphs with OpenGL-Acceleration
* Function-analysis features for all supported graph types
* Integrated C-like script programming language, script editor, programming examples
* Text-based version to use on a console

I've uploaded a .pet here extcalc-0.9.2.pet (980kbytes)

This needs QT AND openGL libs to run. Start by either typing extcalc, or use Menu->Calculate->Extcalc.

N.B For pup4, you need to install qt-3.3.8.pet and then reboot.

Hi. I'm trying to get it to work in Lighthouse Pup 2.15 but so far have had no success despite having installed both the files you mention - extcalc-0.92.pet and qt-3.3.8.pet. Does it only work in Puppy 3 and 4?

Apparently I'm missing a file called libqt-mt.so.3.

Thanks in advance,

Colonel Panic .

I recall someone had problems with some other program, and libqt-mt.so.3 and qt-3.3.8.pet. It might be just a missing symlink. If creating a symlink doesn't resolve it, try removing qt-3.3.8.pet, and instead install the pup2 package, qt-3.3.6.pet.

'Fraid I cheated - I upgraded to 3.01 (vanilla) and the qt and extcalc packages work fine in that.

Thanks anyway.

I'm not having much luck with this program. Here's what I'm getting after I've loaded both pets that are recommended for Puppy 4.

# extcalc
extcalc: error while loading shared libraries: libGLU.so.1: cannot open shared object file: No such file or directory
#

I'm using qt-3.3.8.pet, but I've also tried qt4-4.3.2 with no success.

I'm running Puppy 4.0 on an old Dell Latitude laptop and using XORG for video.

Any ideas what I'm not doing right?

It also needs openGL libs installed.

I know my eyes aren't what they used to be, but they must really be going bad. I didn't notice that in the original post. It works like a champ now. Thank you.

A quick update; what worked in Puppy 2.14 and with qt-3.3.6 was copying the libqt files (all of 'em) over from the /qt subdirectory to the main lib directory. Opera 9.23 shared works now as well.

Thanks for the tip.

@IsntThatAmusing,

I don't understand why you're needing to build qt? Is this for extcalc, or for some other reason? If you need the developer sources for xorg, try this:

xorg_xorg_full_dri_DEV-7.3.pet

I tried to install this to ttuuxxx's 214X the latest version 15.

Initially installed just extcalc-0.9.2.pet which wouldn't run when I entered

Code: Select all

extcalc

at a terminal.

Then added qt-3.3.8.pet, rebooted but got again

Bus error

Also tried using qt-3.3.6.pet as suggested above. Same result. Nada.

Any ideas, anyone, what's missing?

Thanks
Dave

I had trouble with this in Puppy 4 too, but what cured it was getting the gzipped LibGLU tarfile from ttuuxxx's library site;

http://www.puppylinux.ca/tpp/ttuuxxx/Libs/

and then extracting the files to the /lib directory.

Extcalc works fine now.

I think this pet is missing some files. I'm trying to install Avahi-0.6.32 on Wary 5.5 and ./config is looking for something in the bin directory. All I see in this pet is libraries.
