Hi all,
I installed GIFT without any errors and it worked fine with a small
image collection.
I have indexed 169,685 images with GIFT and it took nearly two weeks
to complete it. I think this is the first ever attempt to index GIFT
with a large collection :)
Nope. Others have done 50,000 images and more - if that's large :)
My problem is that, the indexing process did complete, but there was
no *.ADI file generated and the inverted files:
- InvertedFileFeatureDescription.db
- InvertedFile.db
- InvertedFileOffset.db
did not contain anything. Below is the last part of the indexing
messages, and it seems that there was some failure:

This number is -2^31 (i.e. 1000 0000 0000 0000 0000 0000 0000 0000 in
two's complement notation, IIRC). It looks (as Henning suggests), as if
your OS and/or filesystem, like many, has an upper limit of 2Gb on file
size.
