hi Matt,

I've seen this problem before, and hiding somewhere in the shady crevices
of my brain is the answer, but I can't quite locate it.  I suspect that it has
something to do with the include files (*.inc). Try the following:  paste the
text appended below into a new world file (e.g., foo.world), put it in the
'worlds' directory and run Stage against it.

)

position

 port 6665
 pose [1.0 1.0 20]
)

Thanks for the hint Brian - tried it, same error unfortunately.

I'll try rebuilding everything.

Turned out that the problem goes away if I gunzip the image files first.
When I compiled I had errors in that it couldn't find some of the gz
functions like gzgets - these weren't to be found in the copy of zlib.h in
the X11 directory, so I linked from there to a copy of the header that did
have these functions over in /usr/include.

It'll do for the moment...

cheers

Matt

hi Matt,


That's peculiar.  XFree86 supplies its own zlib, but when installing (if you
install XFree86 yourself), you can decide whether or not to install zlib.h.
You might try just removing the zlib.h from XFree86.

Regardless, Stage should give a more informative error than "couldn't load
entity 2", or whatever it said.
