[Doxygen-users] References to directories

[Michael G. <Mic...@t-...>]

Hi doxygen users,

I put documentation for the directories in extra file.

Looking like this:
@dir lib
Directory contains the base of the portal library

@dir lib/billing
Directory contains functions for billing users.

@dir lib/classes
Directory contains base classes

@dir lib/corbaxml
Directory contains the corba bindings to xml data abstraction layer

@dir lib/xml
Directory contains mt-xml-dom data abstraction layer with xpath

The documentation of the directories works fine for me.
Now I want to place references in the mainpage section of the documentation.
f.e.: Look at @ref lib/xml “XML-Sources” for sources related to XML-Data
Abstraction Layer Look at @ref lib/corbaxml “CORBA-XML-Sources” for sources
related to the Corba XML Section

This will not work. I read a warning in the error file saying: 
<unknown>: -1209949816  Warning: unable to resolve reference to `lib/xml´
for \ref command
<unknown>: -1209949832  Warning: unable to resolve reference to
`lib/corbaxml´ for \ref command

I’m using doxygen 1.5.4.
The doxygen hp says, that should work since 1.4.5 (id  314237). So how can I
use this feature or did I miss something.

Kindly regards
Michael
