iostream et STL

You can use wine instead.

It is possible to install nLaunchy in the emulator, giving a permanent install of Ndless. First boot up the emulator with OS 3.6 and install Ndless the usual way. You can transfer the files for nLaunchy, phoenix.tns and nlaunch.tns. Then remove the directory /phoenix (this is why you need to install Ndless in the beginning). Then reboot, and when you get to the os install screen, transfer nLaunchy's fake OS update. There might be an easier way, but this is how I did it.

Then remove the directory /phoenix (this is why you need to install Ndless in the beginning).

Go to maintenance menu and remove the OS. That's easier.

Do you have an easy way of triggering the maintenance menu on the emulator, Excale ?

I've had no problem doing that simply :


In order to "hold" keys, just click on one and hold it while dragging the mouse cursur out of the key. Repeat with other keys.
Then, go to the menu bar and choose Reset CPU (Alt-R)

Edit by Excale: on classic keyboard,

Then, go to the menu bar and choose Reset CPU

Then, press alt+R. (faster)


Edit Adriweb : oui oui

Bon, j'ai reussi a compiler ustl apres l'avoir beaucoup charcute (dans les flux, en particulier fstream). ustl::string a l'air de passer. J'ai par contre eu beaucoup de problemes avec vector, et ca vient en fait d'un gros bug dans l'interface C++ de nspireio, il faut supprimer le ifdef BUILD_LIB dans console.hpp (et uart.hpp), sinon la variable de console a un champ qui est ecrase par toute autre variable, et ca fait tout planter, j'ai perdu toute l'apres-midi a cause de ca. J'ai mis une version qui marche la:

Pour ustl, c'est la (mais pratiquement pas teste pour le moment, et seuls les containers et les algorithmes ont une chance de marcher, pas les io/fstream)

Le pire devrait etre derriere maintenant, je vais bientot pouvoir me lancer dans la compilation de giac lui-meme.

[Lionel Debroux]

Great
ustl's reduced footprint should be a good thing, as long as it has sufficient functionality.

I've sent an English translation of your post to compu, among others.
Other people have looked deeper into porting newlib, reading documentation such as http://sourceware.org/newlib/libc.html#Stubs .

Hi, thanks for fixing that bug!

About the missing float/double support: Nspireio relies on the Nspire's (vs)printf implementation which doesn't seem to support it.

All I can say is that OS 3.1 calls printf with some %g.
Edit: with some %f too.

Of course, this will hopefully be solved once we port Newlib.
