stractures defination in HS08 freescale code warrior

Hi,

Can some one suggest me how to utilize the bit field stracture defined in another, using storage calass in some other file.

Example : /* Var.C */

typedef struct Bit_Flags {
        unsigned SPI_RXTX_Flag :1;
        unsigned Temp2         :1;
        unsigned Temp3         :1;
        unsigned Temp4         :1;
        unsigned Temp5         :1;
        unsigned Temp6         :1;
        unsigned Temp7         :1;
        unsigned Temp8         :1;
}Flag1;

/* Main.c*/

Flag1 Status_Flags;

/*in Main.c below statement gives an error of undefined storage class ? how to specify storage class here? */

Status_Flags.SPI_RXTX_Flag=0;

please suggest the solution .

Thanks

Venkat

Well I would say you need to define the typedef for the structured type in a header file and include the header file in each source file where you are using the bitfield.
