I compile on a linux box (debian 9)


Which SDK are you using? The official CASIO SDK runs on Windows, did you create your own gcc-toolchain with a gcc crosscompiler, linker script, libc, etc?

Is there any C/C++ source of KhiCAS that runs on linux?
I'd like to adapt it to a different platform (Linux/arm PDA).

Thanks
KhiCAS is a variant of xcas layered on top of giac.
What's your PDA model ?
the PDA is Linux/arm-v5, but I am going to move to arm-v6

I'm indeed cross-compiling using gcc for sh3 in a linux box (https://www-fourier.univ-grenoble-alpes.fr/~parisse/casio/sh3eb-elf.tar.gz). If you want to port giac to a PDA, it should be much easier than on the Casio, because you have no memory constraints and probably access to a gcc-toolchain with newlib.
Just got my Casio fx-CG50 and installed Khicas but I have a question:
Where can I find samples of the correct use of all commands? The version I have (1.5.0) only has this in the help
<command>(args)
But cant figure it out the type or number of arguments. After some trial and error I found (for example) that logb has two arguments and only after a couple of tries I understood the order they had to be inputted Sad

Thanx in advance
xcas' online documentation should be your safest source of information, assuming it's up to date Smile

On the fx-CG50 platform, Bernard Parisse had to cut down significantly on features for the program to fit in the maximum executable size of 2 MB.

Thank you!
I asked for help through the comments on a youtube video and the channel owner gave me an answer:

"Here is some information in english : https://www-fourier.ujf-grenoble.fr/~parisse/giac.html
Reference card : https://www-fourier.ujf-grenoble.fr/~parisse/giac/troussesurvie_en.pdf"

Here is the link to the video if anyone is interested. He shows how to solve a bunch of problems with the Casio fg-CG50 and khiCAS (it's in french but you can use subtitles + autotranslate)

KhiCAS killed my FX-9750GIII. I tried to calculate integral(ln(x),x). It took a really long time, so I took out the batteries to stop the calculation (I had done this before and it worked perfectly fine). This time it killed my calculator and it will not turn on. Otherwise really great software.

0x5 it isn't bricked. Sounds like the program just crashed. Have you tried using the reset button on the back of the calculator?

My calculator won't turn on, even if I do the reset button, replace the batteries with new ones, or do the RESET+F2+4+AC for 4 seconds followed by F2+4+AC for 4 seconds, followed by 9 for a second, and finally multiply for a second. It worked fine until immediately after the incident originally described. It's my fault though, I should have just waited for it to error out, instead of removing the batteries. But I would recommend that no one else use reset or take out the batteries during a long computation that you would like to cancel.
