/*! \page trouble Troubleshooting

<h2>Known problems:</h2>

<ul>

<li>If you have problems building doxygen from sources, please 

    read \ref unix_problems "this section" first.

<li>Doxygen is <em>not</em> a real compiler, it is only a lexical scanner.

    This means that it can and will not detect errors in your source code.

<li>Since it is impossible to test all possible code fragments, it is

    very well possible, that some valid piece of C/C++ code is not handled

    properly. If you find such a piece, please send it to me, so I can

    improve doxygen's parsing capabilities. Try to make the piece of code 

    you send as small as possible, to help me narrow down the search.

<li>Doxygen does not work properly if there are multiple classes, structs

    or unions with the same name in your code. It should not crash however,

    rather it should ignore all of the classes with the same name except one.

<li>Some commands do not work inside the arguments of other commands.

    Inside a HTML link (i.e \<a href="..."\>...\<a\>) for instance 

    other commands (including other HTML commands) do not work!

    The sectioning commands are an important exception. 

<li>Redundant braces can confuse doxygen in some cases. 

    For example:

\verbatim

  void f (int);

\endverbatim

    is properly parsed as a function declaration, but

\verbatim

  const int (a);

\endverbatim

  is also seen as a function declaration with name 

  <code>int</code>, because only the syntax is analysed,

  not the semantics. If the redundant braces can be detected, as in

\verbatim

  int *(a[20]);

\endverbatim

  then doxygen will remove the braces and correctly parse the result.

<li>Not all names in code fragments that are included in the documentation

    are replaced by links (for instance when using \c SOURCE_BROWSER = \c YES)

    and links to overloaded members may point to the wrong member.

    This also holds for the "Referenced by" list that is generated for

    each function.

    For a part this is because the code parser isn't smart enough at the

    moment. I'll try to improve this in the future. But even with these

    improvements not everything can be properly linked to the corresponding

    documentation, because of possible ambiguities or lack of

    information about the context in which the code fragment is found.  

<li>It is not possible to insert a non-member function f in a class A 

    using the \\relates or \\relatesalso command, if class A already

    has a member with name f and the same argument list.

<li>There is only very limited support for member specialization at the

    moment. It only works if there is a specialized template class as

    well.

<li>Not all special commands are properly translated to RTF.

<li>Version 1.8.6 of dot (and maybe earlier versions too) do not 

    generate proper map files, causing the graphs that doxygen generates

    not to be properly clickable.

<li>PHP only: Doxygen requires that all PHP statements (i.e. code) is 

    wrapped in a functions/methods, otherwise you may run into parse problems.

</ul>

<h2>How to help</h2>

The development of Doxygen highly depends on your input! 

If you are trying Doxygen let me know what you think of it (do you

miss certain features?). Even if you decide not to use it, please let me

know why.

<h2>How to report a bug</h2>

Bugs are tracked in GNOME's <a href="http://bugzilla.gnome.org">bugzilla</a> database.

Before submitting a 

<a href="http://bugzilla.gnome.org/enter_bug.cgi?product=doxygen">new bug</a>,

first <a href="http://bugzilla.gnome.org/query.cgi?format=advanced&product=doxygen">search</a>

through the database if the same bug has already been submitted by others (the doxygen

product will be preselected).

If you believe you have found a new bug, 

please <a href="http://bugzilla.gnome.org/enter_bug.cgi?product=doxygen">report it</a>.

If you are unsure whether or not something is a bug, please ask help

on the <a href="http://sourceforge.net/mail/?group_id=5971">users mailing list</a> 

first (subscription is required).

If you send only a (vague) description of a bug, you are usually not very 

helpful and it will cost me much more time to figure out what you mean. 

In the worst-case your bug report may even be completely ignored by me, so

always try to include the following information in your bug report: 

- The version of doxygen you are using (for instance 1.5.3, use 

  <code>doxygen --version</code> if you are not sure).

- The name and version number of your operating system (for instance 

  SuSE Linux 6.4)

- It is usually a good idea to send along the configuation file as well, 

  but please use doxygen with the <code>-s</code> flag while generating it

  to keep it small (use <code>doxygen -s -u [configName]</code> to strip

  the comments from an existing config file). 

- The easiest (and often the only) way for me to fix bugs is if you can 

  attach a small example demonstrating the problem you have to the bug report, so I can

  reproduce it on my machine. Please make sure the example is valid

  source code (could potentially compile) and that the problem is really 

  captured by the example (I often get examples that do not trigger the 

  actual bug!). If you intend to send more than one file please zip or tar

  the files together into a single file for easier processing.

  Note that when reporting a new bug you'll get a chance to attach a file to it 

  only \e after submitting the initial bug description.

You can (and are encouraged to) add a patch for a bug. If you do so

please use PATCH as a keyword in the bug entry form.

If you have ideas how to fix existing bugs and limitations please discuss them on 

the <a href="http://sourceforge.net/mail/?group_id=5971">developers mailing list</a> 

(subscription required). Patches can also be sent directly to dimitri@stack.nl if 

you prefer not to send them via the bug tracker or mailing list.

For patches please use

"diff -uN" or include the files you modified. If you send more than

one file please tar or zip everything, so I only have to save and download

one file.
