Hello David, thank you very much for your support!
Yes, htdig is reading a.pdf-file. pdftotext and pdfinfo are working ok, too. But when I run conv_doc.pl (or doc2html.pl ) from command line with a pdf-file as a argument I get error message: bad interpreter: no such file or directory/usr/bin/perl. What is here wrong??? best regards Natalya > OK, so far we have established: > > 1) Htdig is reading a .PDF file > 2) You are attempting to use /usr/local/bin/conv_doc.pl to convert it. > 3) No text is being extracted from the .PDF file, so it is not being > indexed. > > This suggests that the fault is with /usr/local/bin/conv_doc.pl.
