ExtendeD is still working on Ndless, and has just solved technical issues that prevented C++ support from being implemented in Ndless.
Here you go for a brand new version of Ndless

The first C++ programs for Nspire have been coded by tangrs a while ago, but the issue was that elf2flt was not handling some relocations with recent GCC versions for ARM. This caused issues with hoffa's nSDL, and was reducing the number of programs you could port for the Nspire.

Now that the issue has been identified, ExtendeD patched elf2flt and published :

• Ndless r825 SDK, with official C++ and bFLT format handling (much simpler than ELF, it was specificly made for embedded devices) for Ndless programs. bFLT is now the recommended format for object files.
  
• Ndless r825, compulsory to run C++ programs (with or without nSDL);
  
• YAGARTO & MSYS binaries for Ndless r825 SDK. Linux will need to compile elf2flt by themselves: follow the steps on Hackspire

Here's a preview of the new features of a direct port (with small changes to adapt to the platform itself, like keyboard, resolution...) showing what c++ with nSDL can provide, with a quick  port of Advanced Tetris by GDO, by Extended :

That's fantastic news. I'm sure a lot of coders will be really happy!

Oh great, now you're making me doubt again wether I should learn C or C++ J/k, fatastic work!

So does the use of bFLT mean that the issues with global variables are now also solved?

Yes You can thank tangrs for this.

That is very great news !
Iirc, some emulators people wanted to see ported (Sega for example) couldn't be be ported from C (because no one coded them in C) but existed in C++, so maybe we could see those emulators coming now ?

Just make sure that the emulator is properly coded in its current form before considering porting it to a weaker platform. I remember some NES emulators like JNES that could barely even run on a Pentium II 350 MHz (got like 8 FPS), yet Nesticle and FCEU would run at 60 FPS.

I think that we will see lots of new games on the next times I really want to see that SEGA emulator (working on the black/white nspires too)
by the way, it's now possible to make a GBA emulator compatible with the non-cx nspires?

I think classics' hardware is too weak for GBA, else gpSP would have been realeased to it too.

that's great news
