How is debugging property of EMI?
(maybe you were listening to some music during the debug session and youtube spotted them?)

@Hoffa what bugs are you encountering in fact ? Today I tried to port only the gif loading, and I didn't get any error other than "This file type is not supported" always. I just compiled SDL_image.h, IMG.c and IMG_gif.c (and removed all dependencies like constants and strings relatives to other formats). I just gave up after a few hours ;D but maybe I can help you debugging.

@Excale in fact it's "Cette vidéo n'est pas disponible dans votre pays" but I don't know how to say it properly in English :P

Probably because I used "Don't Worry, Be Happy" as the background music.

Yeah you have to define LOAD_GIF for it to even compile anything (otherwise it just compiles virtually empty functions, that's why you got the error). I have no idea what the issue nor do I want to think about it. It's some mix of relocation issues with ndless and pure magic. The behavior was irregular and completely illogical to even the most experienced human mind. Shit breaks down when it feels like it, next build doesn't, works with while but not for, reads one string but not the other, doesthefuckdoiknowwhat, etc.
It's worse than writing Brainfuck or Java, or trying to solve a Rubik's cube.

EDIT: Offtopic, but I got out of the Finnish Army this Friday. No more conscription. No more shaved head or asshole sergeants using you as a puppet. No more waking up at 6 AM, no more spending two weeks in the forest. No more 30-hour-long 70-km marches with 60 kg "camping" equipment on your back. No more APILAS, no more RK62, no more M72, no more TM 65 77, no more NSV. Feels great to back in normal life!

At least it wasn't copyrighted by Sony Music Entertainment. If that was the case, your video would look suspicious, since a SME copyright block/warning is a very huge sign of rickroll. ;D

Anyway yeah debugging is annoying, and in my case I found it annoying with just TI-BASIC. I can't imagine how bad it must be with lower level languages. >.<

Done!

I finally managed to port SDL_image. The relocation issues were so frustrating I today decided to hardcode the cancerous part. Here's nSDL drawing the OpenBSD fish loaded from a GIF file:



Using the freshly ported SDL_image (which can be downloaded, as usual, here), you can now load images of the following formats: GIF, LBM, PCX, PNM, TGA and XCF.

You should now be able to use much less memory to store those pictures as opposed to using BMP (or the in-code NTI format). GIF images are usually at least 4 times smaller than their BMP counterpart.

Is nDraw part of nSDL or is it a separate project?

There's no such thing as nDraw. Blitting (or "drawing" as I referred it to) is all part of standard SDL.

Great news! Hopefully this makes Matrefeytontias' F-Zero clone much smaller :P (currently, just one race track is 1 MB large)

So the picture on the first page no longer applies then.

Yay, awesome :D thanks a lot for it, I'll make a great use of it (especially with F-Zero yeah ;D )

ExtendeD I really would like you to fix the relocation issues, it's unbelievably horrible (but I suppose you know more than well enough the feeling I'm feeling right now, so no hurry).

Sorry about that. I really need tangrs to debug the issue with the bFLT loader and nSDL.

Here's nSDL drawing the OpenBSD fish loaded from a GIF file:

How did you make it to have the right colours from a gif file ? I'm loading a gif image from /documents/Examples/map.gif and it doesn't have the right colours at all ... Have I to save it as a gif with 16-bits colours ? If so, how can you do it with Gimp ?
