missing type definition

Dear all,
I generated C code from function block diagram, in which I see the following lines

extern int32 *BF_ANA;
extern uchar *BF_BOO;

#define _SCC_FZPF_ID0200314_OUT2_VA 0X0413
#define _SCC_MYAVFBD_OUT2 0X0411
#define _SCC_MYAVFBD_OUT1 0X05FB
#define _SCC_FZPF_ID0200314_OUT1_VA 0X05FF


BF_BOO[ _SCC_MYAVFBD_OUT2 ] = BF_BOO[ _SCC_FZPF_ID0200314_OUT2_VA ];
BF_ANA[ _SCC_MYAVFBD_OUT1 ] = BF_ANA[ _SCC_FZPF_ID0200314_OUT1_VA ];

I suppose BF_ANA and BF_BOO have been defined in some other header files which is not given out after code generation. Can someone help me how to define these items?
Thanks

What do you expect us to do with snippets of meaningless symbols generated by some auto code generation tool?

Well you could do
int32 *BF_ANA = malloc( pickHoweverManyYouNeed * sizeof(*BF_ANA) );

Or perhaps your model is wrong, if it's emitting declarations for things, without the definitions.

BF_ANA and BF_BOO would be defined in source files, not headers.
