Doxygen LaTeX / PDF links point to page 1 -
i using doxygen create product manual, , ran issue.
some links in outputted pdf (created latex) broken; point first page of document.

the accompanying html output not suffer issue; links work fine, shown below:

the doxygen code page:
/**      @mainpage [product] developer's guide      blah blah blah.      manual divided following sections:     - @subpage intro     - @subpage [etc]  */   further notes:
- i tried @ref instead of @subpage. no difference.
 - some other references in pdf broken (automatic file references in sections), many work fine.
 
here's latex intermediate page:
this manual divided following section\-: \begin{doxyitemize} \item \hyperlink{intro}{product introduction} [etc]   edit: manual solution found
- open refman.tex latex output directory
 - change entry 
\hypertarget{d1/dfb/intro}{}\hypertarget{intro}{} - repeat other pages
 - run latex pdf tool
 
this not viable solution automated processes though, question still open.
