A viewer of PDF
« on: January 03, 2013, 04:34:02 pm »
Hello everybody !

I think that it would be great to adapt a lector of PDF for TI-Nspire from ozbookr. Its size is maximum 1.2 megas et works perfectly on PSP with 222MHz.
But there's some problems :
1) It is coded in C++ and it seems that some C++ codes don't work on TI-Nspire (very weird because we should do every thing we want).
2) To compile the library freetype needed, the command "make" doen"t work with ndlesseditor.

For this project's developpement, I suggest to the most experiment of you to do it (I won't have the time). For example, extended, Levak, tangrs.

Imagine a lector of PDF on TI-Nspire :

Bonjour à tous !

Je pense qu'il serait bien qu'il soit effectué un lecteur de PDF pour TI-Nspire, adapté de ozbookr. Ce programme fait maximum 1.2 Mégas et tourne parfaitement à 222MHz sur PSP.
Mais voici les problèmes rencontrés :
1) C'est en C++ et il parait que tout ce qu'il y a en C++ ne marche pas pour TI-Nspire (ce que je trouve vraiment très bizarre vu que théoriquement, on devrait tout pouvoir faire.
2) Pour compiler la librairie freetype nécessaire, bizarrement, la commande "make" ne marche pas avec ndlesseditor.

Pour le développement de ce projet, je propose aux plus expérimentés d'entre vous de s'y atteler (moi, je n'aurai pas le temps). Par exemple, extended, Levak, tangrs.

Imaginez un lecteur de PDF pour TI-Nspire :

'making' from the Ndless Editor is possible, just open a console with Tools > Ndless SDK console.

C++? I'd wait untill ELF or bflt are integrated into ndless.
That would make it a whole lot easier.

tangrs's bFLT support has actually already been integrated into Ndless's SVN trunk, but seems to conflict when linking with nSDL.
As I don't know much about the bFLT format and the linker's magic I'm unfortunately stuck, any help is welcome.

ELF is available, iirc tangrs made it, but I don't know how its current state of development is.

I don't even know what bflt is..
I googled it, it's not even directly supported by gcc, is it?
What are the advantages over ELF, which would be easier to work with?

BTW: I can't find the svn repo for ndless..

The repo is at https://www.unsads.com/scm/svn/nsptools/Ndless/trunk

bflt is much easier to write a loader for than ELF.

"Authorization Required"

But tangrs already wrote an ELF loader.

I think there was also some issue with much bigger executables or something. And I'm not sure the loader was finished and bug-free.

Edit: It's not finished.
Also it's two times guest.

ELF is much more complex than bFLT is. An ELF loader is a complicated piece of code (well, that's not so much of a problem, as long as it works), whose binary has some weight (more of a problem on such low-powered embedded platforms), and ELF binaries can be surprisingly large, according to tangrs' own tests.
bFLT is a simple format, which supports .text, .data, .bss, and relocations involving those; it can be easily produced from ELF input. It's more suitable than ELF to such low-powered embedded platforms as ours.

Why would we need to statically link our modules?

Not sure what you mean, as bFLT supports dynamic libraries ?

I am trying to get my permit and using nTxt is dangerous to read files, and my PDF to text converter of choice isn't perfect. So, this project would be amazing

Keep trying.
