struct - __attribute__((packed)) not working?

[Liam Staskawicz]

Hi - I have a struct that I'm having trouble generating documentation  
for.  Here's generally what it looks like:

/**
   \struct MyStruct
   My great struct.
*/
typedef struct
{
   int id; /**< id doc */
   union
   {
     char data[100];
     myType t;
     myOtherType o;
   }
} __attribute__((packed)) MyStruct;

All that gets generated is a stub page with the title MyStruct and any  
further description I add to the main doc block - no member  
documentation. When I remove "__attribute__((packed))" then I get some  
nice member documentation - the nested union thing still works a  
little strangely, but I'll figure that out once the of it's working.

Any hints?  Thanks very much!

Liam

You can let doxygen's C-preprocessor remove the __attribute__ stuff  
with the
following settings:

ENABLE_PREPROCESSING   = YES
MACRO_EXPANSION        = YES
EXPAND_ONLY_PREDEF     = YES
PREDEFINED             = __attribute__(x)=

P.S. The \struct command in your example is redundant and can be  
removed.
