[Doxygen-users] doxygen #define question

[<hew...@gm...>]

Hi there!  I have a question regarding the doxygen preprocessor.  In some of my code (.c) modules I have a #define setup to tell the .h file for that module how to behave.  For example in the following file (driver.c) I define the constant CDR:


#define CDR
#include "driver.h"


/**
 @brief Initialize all CAN1 Driver variables.
 @return none
*/
void initialize(void)
{
 //! @todo Run some code here...
 printf("%d", test_file_scope_variable);
}


Then in the header file (driver.h), I perform certain actions based on whether CDR has been defined.  For example, the static variable test_file_scope_variable below is only declared if CDR is defined.


#ifdef CDR /* LOCAL definition */


/**
 @var test_file_scope_variable
  File Scope variable to Test doxigen
*/
static u16 test_file_scope_variable;


#endif /* CDR */


All the above code works great at the compiler level but when I go to run doxygen the documentation generated never shows test_file_scope_variable since doxygen can't seem to see that CDR has been defined in the C module.  Does anyone know how to solve this?  I know that I can solve this by defining CDR using the PREDEFINED setting in the doxygen settings.  However this will define CDR for the whole project and I only want it defined only for this module and header combination.



Thanks!  Any help would be greatly appreciated!
