I have 0,1,9 version running on a redhat env. I have succesfully indexed 
42.000+ images and have had no problems.
Wolfgang. I am getting a new machine and will be glad to test the new version, 
but that wiull have to be after the christmas break. Perhaps sometime in 
seasons'  gretings.

I would like to know if there are any installations of gift dealing with
collections of a number greater than say 40 thousands images or so. Reason
is: I have to deal with such a collection and ran into problems with
value-ranges of integer-type while indexing :)
Last lines of gift-add-collection were:

MERGESORT MergeSize 805306368
MERGESORT MergeSize 1610612736
MERGESORT MergeSize -1073741824


Copying /data02/gift/gift-config.mrml to /data02/gift/gift-config.mrml-old


Gift was starting but didn't feel well afterwards and crashed. Well, I said,
given that the number doubles every iteration the mergesize would hit the
range of "signed int" the last time. What I did was changing the type in the
sources to be a "unsigned long" which made the indexing succeed

Unfortunately I'm stuck to version 0.1.9, compiling more recent versions
failed because of compiler-issues, so this might already be fixed in the
current version. Is it?

The gift gives amazing results most of the time, sometimes the result are -
ehhh... - a bit strange though. Now I think there might be other places
where similar issues could come up with that collection-size, and I wonder
if that's the reason for the rather esoteric results. Changing the
build-environment is on the way but will take some time. Maybe there are
other ways like reducing the number of extracted features or so?

So where are these large collections and how are the experiences?

Best regards,

It should be. Within the next 48 hours I would like to send you a version of
which I would be glad if you'd test it in order to see if it makes it on the
FTP server. It plays nicely on my Gentoo, the non-root install problems seem
to be fixed. I would be very thankful if someone else than myself would test
