I saw on Aminet that Stefan Haubenthal uploaded a MOS version of TDFSB (3D filesystem browser) and it seems like a neat little utility so I tried to compile it but I'm getting some errors and can't quite figure out if it's me missing something or SDL_image.a missing some functions.

The errors I get all pertain to functions starting with jpeg_, png_ and TIFF, like:

Quote:

/SDK/local/newlib/lib/libSDL_image.a(IMG_jpg.o): In function `IMG_InitJPG': /Work/SDL_image-1.2.10/IMG_jpg.c:155: undefined reference to `jpeg_std_error' [...] /SDK/local/newlib/lib/libSDL_image.a(IMG_png.o): In function `IMG_InitPNG': /Work/SDL_image-1.2.10/IMG_png.c:250: undefined reference to `png_sig_cmp' [...] /SDK/local/newlib/lib/libSDL_image.a(IMG_tif.o): In function `IMG_InitTIF': /Work/SDL_image-1.2.10/IMG_tif.c:111: undefined reference to `TIFFSetErrorHandler'

I was using some older SDL_image includes from EvilRich I think, so I updated my SDL_image SDK files with the latest archive on OS4Depot but it produces an even longer list of undefined references.

I added AmigaOS to the compile.sh file and it's command line reads:
Quote:

gcc tdfsb.c $ARGS1 $ARGS2 -I. -lSDL_image -lGL -lGLU -lglut -O2 -o tdfsb;

Any clue?

@AlexC

Yep, you need to link it with libtiff and libjpeg too.

Edit: and libpng, and probably libz. -ltiff -lpng -ljpeg -lz. Try that.

Advice for the future: for this kind of OS4.x tech questions I suggest you post them here: http://www.amigans.net/

All developers dwell there (including many that don't visit here).

Thanks for the hint, that was it, unfortunately the exe it produced was crashing on launch.

afxgroup gave me a hand and compiled a more stable binary which shows previews of image files and videos. That's about all it does at this stage.

Unfortunately it needs a lot of changes to be remotely useful on the Amiga and I'm not sure it's worth the effort. I'll look around for some better written alternative if there's any.

It's hard enough for me to keep up with one forum and there's probably more coders here than there as there's people from all 4 flavors of the OS.
