The problem is when adobe comes out with a new version of the file format it is incompatible with older versions, for example some new pdf's cannot be imported into Greenstone. This is noted in the log:
"PDF version 1.6 -- xpdf supports version 1.4"
The solution would be to convert existing pdf's to an older version such as 1.4 or earlier. If the pdf's were produced from some other files using a program like Open Office should produce pdf's that Greenstone can use.
http://www.topshareware.com/pdf-1.6-to-pdf-1.4/downloads/1.htm lists PDF Version Converter 1.0, a program that converts Convert PDF file between different versions for compatibility purposes. I've not tested this. Should be other programs or even a web site that performs a similar function, a program that works in batch mode would be preferable.
