Hm, doesn't seem to work. Let's try the X11 version:

   make ams-x11
   ./build.pl -i exhibit graft skif minivx xv68k freemountd interact-x11

   ...

   T=0.275s  ERROR:    OpenDF is unimplemented

Nope, it seems to be missing something. OpenDF? All I find is this: https://github.com/PrjEnt/OpenDF, a long-abandoned project which seems to be a more compact version of another abandoned thing.

I think they mean FSpOpenDF (https://dev.os9.ca/techpubs/mac/Files/Files-53.html#HEADING5...), a (relatively) late addition to the Mac API.

  • The FSSpec calls added in System 7 are mostly new interfaces to existing File Manager functionality. There's an actual high-level `OpenDF()` call, which is like `FSOpen()` except that it won't try to open a driver when the name begins with `.`.

    Some applications call `OpenDF()` without checking its availability, but fall back to `FSOpen()` or equivalent if `OpenDF()` returns `paramErr`, which is what the parent is witnessing. See `68k/modules/ams-fs/Files.cc` in the `metamage_1` repo.

    If the error message is confusing people, maybe it's time to implement `OpenDF()` for real.

Ah, yes, the two front ends I haven't touched in years. This should be fun. :-)

You clipped the part that said "Starting VNC server on 127.0.0.1:5900". Did you try connecting a VNC client?

OpenDF is a MacOS toolbox call (which is apparently not implemented)

  • Strange it errors out on given that I assume the thing does run elsewhere. The X11 version sometimes shows the opening screen but any attempt at interaction leads to the mentioned error. The VLC version shows the error directly.

    • Any interaction with the Welcome application terminates it. Try setting AMS_APPNAME=Tic-tac-toe in the environment, or AMS_APPNAME="Nyanochrome Cat".
