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.
