First you need to install Adobe Acrobat Reader on your server. Get the
latest version from:
http://www.adobe.com
Second, you need to run the patch that's included in htdig-pdf.tgz,
available at:
ftp://sol.ccsf.cc.ca.us/htdig-patches/3.0.8b2/
Don't compile it yet because ...
Third, make the following changes, as pointed out by Sylvain Wallez:
<start quote>
The first one is a bug in PDF.cc (doesn't seem to happen on the PDF
files on my Intranet, but we only use Acrobat to produce them). Here's
the diff he sent me :
diff -c htdig/PDF.cc.old htdig/PDF.cc
*** htdig/PDF.cc.old Wed Jul 15 10:46:03 1998
--- htdig/PDF.cc Tue Jul 14 10:21:38 1998
***************
*** 280,286 ****
}
}
! else if (line == "BT")
{
// Beginning of text block
if (debug > 3)
--- 280,286 ----
}
}
! else if ( mystrncasecmp( line.get(), "BT", 2 ) == 0 )
{
// Beginning of text block
if (debug > 3)
The second problem is that the default value for the "bad_extension"
attribute contains .pdf, which causes all pdf files to be ignored by
htdig, even if a parser is available.
To correct this, you can either put a "bad_extension" list without
".pdf" in your config file (this is what I did), of apply the following
patch to htcommon/defaults.cc :
diff -c htcommon/defaults.cc.old htcommon/defaults.cc
*** htcommon/defaults.cc.old Fri Aug 15 01:59:25 1997
--- htcommon/defaults.cc Mon Jul 13 19:37:33 1998

Thanks to M.J. Long for bug hunting.

Now, you can do a configure, make clean, make and make install. Voila, PDF
parsing!
