!Cretin

Hi James,
Glad to hear you are still around!
The version Chris posted has been running nicely on a Pi4, for the last 24 hours.

If you could check for the missing files, that could be great, if possible some instuctions to build the source would be awesome, especially for us learning C on RISC OS.

Works fine for me. Thanks for getting this up and running. Using it on my Pi4 now, will test with my Titanium when its up and running.

I seem to be getting a segmentation fault.

Fatal signal received: Segmentation fault

Stack backtrace:

Running thread 0×9904c
( 9cf30) pc: 7f8e0 lr: 7fe30 sp: 9cf34 __write_backtrace()
( 9cfa0) pc: 7fa04 lr: 585bc sp: 9cfa4 __unixlib_raise_signal()
( 9cfb0) pc: 584c0 lr: 0 sp: 9b754 __h_cback()

Wow, what an unpleasant dump that is.

Because if how the Unix stuff works, the backtrace is always __unixlib_raise_signal() (etc) instead of what actually failed. It looks like PC is referring to the failed instruction, not two beyond (LDR is likely to fail, ADD isn’t – not a big deal but differs from the rest of the OS), and the mindscrew of giving the register dump in APCS notation and the disassembly as straight registers.

I’m guessing the bit at the end is a better indication of what happened, in this case Msgs__Find() being where the problem occurred? It’s trying to load a word from address &9B77A which is 636794 which when divided by four is 159198½ and there’s the reason why the machine said “nope”.

Which caused me to poke the buttons on the elderly Casio fx-115.¹ and wonder whether that might have been a miss of 9b778, slightly misaligned.

¹ Until I looked I hadn’t recalled the “mode” button that changes Dec 0, Bin 1, Oct 2, Hex 3, Deg 4,…
Mostly loving the number of batteries it uses :)

I forgot to mention this version of Cretin needs alignment exceptions turned off.

Hmm, could only find a manual for the 115s, but that implies the non-solar power source is a single button cell…
…which would run for years.

Might be an idea to detect and warn? Better user experience than a segfault. ;)

I located it in a box that had been stashed in the garage for the last 16 years and I suspect the button cell left this plane of existence some while back.
Opening the case might be “interesting”

Anyway – topically: Alignment

Edit Opened, can’t see a battery. There seem to be multiple models This one seems to max out the solar cell area
