I will check it out !!!!

Well done.

Thank you!

It's quite a friendly horse. I'm using Ubuntu 20.04.2 LTS in a Virtualbox virtual machine running under Windows 10. With a few exceptions, everything just works using the gnu compilers. No need to worry about particular versions of anything!

Yes. However, see below ....

I'm intending to do this myself before long. It isn't quite trivial - at present, my program is based on the "vanilla" WP34s code. All of my changes are nicely encapsulated in #ifdef DM42 ... #endif tags, so they are easily identifiable, but they will have to be copied across to the WP34c code. In some cases this is easy - for example, storage.c is identical in wp34s and wp34c, so it can simply be replaced - but in other cases it might be a little harder. It might be wiser to let me try first - you seem to be pretty busy elsewhere at present! However, you're welcome to have a go.

One feature of the WP34s is that programs are stored not as text but as opcodes. So if extra commands are added - for example, by changing features.h - some opcodes may change, unless the new commands are added at the end of the existing opcodes. This risks breaking programs that users currently have stored in RAM or in libraries. Actually, enabling SIGFIG mode doesn't cause a problem. But other commands might. Before I go all-out and turn everything on I want to make sure that as many extra commands as possible go at the end of the basic set of commands already present. If you aren't worried about preserving existing code, or you're happy to use the assembler suite to recompile things, this isn't a problem.

If you do decide to compile it, let me know how it goes! I'm sorry that I didn't do a Windows makefile, but I couldn't get anything to work under Windows at all. I can't even run the WP43s/c demo programs under Windows. (My laptop is OLD.) In any case I find makefiles particularly intellectually challenging; I'll jump on any excuse to make them simpler.

Best wishes
