Do you have the update relating to LargeFiles installed? I'm afraid I
forgot to mention it - that update is what provides the

You have to have an exports file for the internal plugin mechanism to work, so yo can see why it is important! I am driven to surmise that you must have tried to generate the internal plugins _without_ having generated the code vm first. Is that correct? Currently that can't work, though I imagine there might be a way to make it possible (it would involve some interesting gymnastics though).

Yup, you got caught by the minor tumroil in the SF repository at the
moment. It is being fixed, and the off_t is replaced with a more
abstract name that can be defined for each platform without clashing
with assorted OS names.

I guess something like that might be useful. I think some indication in
the VMMakerTool would be better; one thingI want ot get to is catching
the assorted progress exceptions and make the progres bar fit into the
tool rather than splat all over the screen.

I didn't need to do that for some reason; oh of course, I already have a
copy of FileCopyPlugin on my machine. With luck, this will become a
non-issue soon since we expect to move to a non-copying-of-files strategy.
I'm not in a position to commit anything to SF for a couple of days
since I have to get on the road to pack up my milling machine and
deliver it to a buyer - no income means I'm having to start selling
stuff to pay the mortgage. Not fun :-(
