Do you by any chance still have the compiler log showing which files were
In my test I was able to get all the Sumo stuff to compile. There were no
missing files, just some outdated references because of the apparent
removal of the toplevel blender/source/sumo directory. The Sumo
files were all still in blender/source/gameengine/Physics/Sumo directory.

No, I am not, but with the current code/Makefile structure it was maybe 1-2 hours
work to test out to see what was missing with Sumo. The more removed Sumo becomes
from the codebase, the more difficult it is to test it out. My concern was that
a total excising of Sumo code will make it very unlikely to ever be integrated
into Blender again (because Blender and its make system will certainly evolve,
and removed Sumo files will never be looked at, much less updated, by developers).
As for me, I am managing all of the Blender sourcecode locally in my own Aegis
repository and syncing manually with CVS, so nothing that happens in CVS can
negatively impact my work. The removal of Sumo stuff therefore doesn't affect
my (to date very minimal and experimental) work in this direction, but it might
discourage other potential developers, with more time, from working on this project.
Since the stuff is already removed, and the focus is now, as you say, on
getting a buildable version, I'd say just leave the stuff removed. After
the build system is stable then you/I/someone else can re-add the Sumo
files at the appropriate places (determining those "appropriate places"
is difficult for new developers, like me, which is why I also am paraoid
about removing almost-working code) and make a conditional compile for Sumo
with the new build system.

Sounds interesting. What do you mean by loaded dynamically? As in, real
dynamic libraries? Does Blender currently build any dynamic libraries at
all? Hm, cross-platform support for dynamic libraries is certainly a fun
can of worms to open. I know "libtool" is designed to deal with exactly
this problem (building shared libraries in a platform-independent way),
but I don't know exactly which platforms it supports (I know GNU/Linux is

Ton's been adjusting some mailing list parameters, maybe it has something
to do with that.
