My pdf indexing worked fine in htdig-3.1.0b2 and gives lots
of errors after I updated to 3.1.0. I have the following in my conf file:
pdf_parser: /usr/local/bin/acroread
max_doc_size: 5000000
..
Here are some error messages:
Error: Can't open display:
PDF::parse: error running pdf_parser on http://xxxxxxxxxxxx/xxx.pdf
I've never seen this "Can't open display" error before. Seems like
it wants to run X GUI Acrobat reader.
Any ideas?
