I think I’m chasing a struct packing issue

i386 breaking on the AASTINKY texture

On the i386 a texture info lump loads up just fine. However on a big endian G5…

OS X 10.2.8 on the G5 on the same AASTINKY

…It clearly has problems. Although notice that the positions and sizes are the same, as they ought to be.

Notice how originx is 24, which should be the width. This code was running with GCC 1.30/1.40 hammered x68000 GCC. Although I have been unable to get the much vaulted gcc-1.30.atari.tar.bz2 to do anything useful, well until tonight, when I found this file: GNU_HEAD.ARC.

That’s right, it’s the gcc-1.23 release headers for GCC on the Atari ST. Now I know other places people have been saying I should use MINT or some GCC8 port. And I wanted something to run on bare TOS, and I cross compiled the simple Infocom interpreter but it just crashes out after a few commands. It’s hardly stable.

3 bombs and an exit under GCC 8.0

Which is just a damned shame, as it was easier to just download someone else’s work.

Anyways, I now can build the old gcc-1.30 libc however… the linker that I’m using that works for GCC 2 links away and it looks like a working program but it doesn’t do anything. I have a feeling the linker drifted in those years between GCC-1.30 and GCC-2.something when it was adapted. Certainly by the time of 2.5.8. So yet more endian ghosts to chase down if I try to adapt that linker.
