I am using Doxygen to create a product manual, and I ran into this issue.

Some links in the outputted PDF (created from LaTeX) are broken; they point to the first page of the document.

The accompanying HTML output does not suffer from this issue; links work just fine, as shown below:

The Doxygen code for this page:

```
/** 
    @mainpage [product] Developer's Guide

    Blah blah blah.

    This manual is divided into the following sections:
    - @subpage intro
    - @subpage [etc]
 */

```

### Further notes:

* I tried @ref instead of @subpage. No difference.
* Some other references in the PDF are broken as well (automatic file references in some sections), but many work fine.

Here's the LaTeX intermediate for this page:

```
This manual is divided into the following section\-:
\begin{DoxyItemize}
\item \hyperlink{intro}{Product Introduction}
[etc]

```

Edit: Manual Solution Found
---------------------------

* Open refman.tex from the LaTeX output directory
* Change the entry `\hypertarget{d1/dfb/intro}{}` to `\hypertarget{intro}{}`
* Repeat for other pages
* Run the LaTeX to PDF tool

This is obviously not a viable solution for automated processes though, so this question is definitely still open.
