Compiling Error131: Macro is defined recursively

[norman_tan]

Hi All,
Has anybody ever met compiling Error131: Macro is defined recursively?
and how to solve this question if you met it before?

In my codes:
#define PBC_INT_DATA_ATTR

#define PBC_EXTERN_ATTR extern
or
#define PBC_EXTERN_ATTR


#define PBC_DATA pbc_data[handle].
//extern struct pbc_data PBC_INT_DATA_ATTR pbc_data[];

#else

#define PBC_DATA pbc_data.
//extern struct pbc_data PBC_INT_DATA_ATTR pbc_data;

#endif

and,

struct pbc_data
{
V1SL_SYS_PBC_DETAIL_PTR detail_ptr; /* detail-pointer of the related device */

V1SL_SYS_PTR_TYPE c0c1_sys_ptr; /* sys-pointer of the related device C0C1 */
V1SL_SYS_PTR_TYPE c2_sys_ptr; /* sys-pointer of the related device C2 */

V1SL_SYS_PATH_TYPE c0c1_sys_path; /* sys-path of related device C0C1 */
V1SL_SYS_PATH_TYPE c2_sys_path; /* sys-path of related device C2 */
...
}


Command line below will cause Error131 :"Micro is defined recursively" during compiling:

#ifdef V1SL_CFG_ENVIRONMENT_MULTI_DEVICE

PBC_EXTERN_ATTR struct pbc_data PBC_INT_DATA_ATTR pbc_data[PBC_DEVICE_NUMBER];

#else

PBC_EXTERN_ATTR struct pbc_data PBC_INT_DATA_ATTR pbc_data;
#endif

I do not know how to solve this error and ask help here.

Thanks a lot!

pbc_data == PBC_DATA......

Unless you turn strict typing on, CCS runs with case significance turned off. You have a define called PBC_DATA, and a variable called pbc_data. Result two different things using the same name.....

So this:

#define PBC_DATA pbc_data[handle]

Is trying to define something in terms of itself. Hence 'recursive'.

Hi Ttelmah,

CCS told me add command line "#case" at the start of the program will solve this problem!
I have tried it, CCS is right.

Thanks a lot!

as I said: "turn strict typing on".

#device ANSI also forces this. Which you need is dependant on what you actually want to do...
