RE: Problem declaring struct and union


What is a VUINT32?

If you add:

typedef volatile unsigned long VUINT32; 

before the struct definition
I find it compiles... Of course VUINT32 may not be 
a volatile unsigned long, and an unsigned long may not 
be 32 bits wide on your machine. You would have to check this.

I think it is okay to have unnamed fields as this provides 
for padding.

Cheers

John

 Hi together,



my name is steffen and I use the gcc 3.4.4.

I have got the following code and I don`t understand why it will not be complied.



struct INTC_tag {

     union {

          VUINT32 R;

          struct {

               VUINT32:26;

               VUINT32 VTES:1;

               VUINT32:4;

               VUINT32 HVEN:1;

          } B;

     } MCR;

};

The error is:

warning: no semicolon at end of struct or union

error: parse error before numeric constant



Can anyone help me please ?!



Thanks



Steffen
