Title: On-calc C compiler for 9860
Post by: flyingfisch on August 30, 2011, 08:55:36 pm

Does anyone know of a way to compile c on a calc?

Hmm good question, I do not remember seeing one, but a while ago somebody talked about a tool that let people program some sort of language on-calc. I think it was a derivative of BASIC, though.

I remember seeing that on CK.

BTW: does text in mlc work on your hacked calc?

Now that there is the gcc SDK for the prizm someone should port it over to the fx-98 series first off. Then secondly the compiler can be slightly modified and recompiled for the the fx-98. i believe the only thing that needs to be done to have gcc for the fx-98 is write a new linker script and crt.s file which should be rather simple. Then for the on calc version the modifications are a little more intense. the linker script and crt.s file will stay the same but the compiler itself will require a partial STL library to be ported for file io and the console to work properly. it will also require that a new main function is created that allows the user to select the proper file and then calls the original main. I was going to attempt this on the Prizm soon but i could also make an fx-98 version too with only minor modifications

No problem. I'll check Simon Lothar's documentation on the fx-98 series so I can modify the proper files to work correctly. I will also rewrite mkg3a into a new mkg1a unless such an app already exists. Basically I will turn this Prizm exclusive project into a Casio calc harmony one instead :)

I think this has already been done. If you take a look here, there is a link for using gcc to compile c programs instead of casios sdk. also g1a wrapper should be the analogon to mkg3a...

I should add some userbar/avatar flavor... my post always seem so short :)

This is cool! I would be more interested in c if I could do it on my calc since it would be portable and I just find programming on my calc more comfortable.

Hey, z80man, are you currently working on this project or are you going to. (not trying to nag you or anything LOL)

I'm going to later on but right now it is a fairly low priority. There is still plenty of documentation to be done and I have a shell to write also.

OK, cool! Be sure to let me know when you start on it!
