Reading the mailing list, this is apart of my study interest.
One of my task will be working on how to integrate retrieval by image
region using some code, and I am planning to make it as a GIFT plugin.

I have a copy of plugin-how-to written in May 2003 by Alex. I don't know
whether it is still ok to follow that (if there is a latest
document, can I have a copy). Anyway, I tried the PluginMaker
according to the document. It did create a Gift plugin
templete. Based on the document: without changing anything, I should be
able to compile and
install the empty plugin. But, when I "make all" it gave me this error:

Hope you can help me. If not mistaken, David mentioned that one of his
student
have done something on region based retrievel with GIFT, Is there any
paper that I can read regarding this matter?

Thanks,
