structure declaration not supported

Inititalize the struct in a loop. for(p= (char *) alt_tfsdevtbl,i = 0; i < sizeof(alt_tfsdevtbl); i ++) { *p++ = 0xff; }

Hi,

There is NO direct replacement in Codewarrior for the structure declaration you are referring to. Although I am not familiar with the Cygwin/gcc compiler you mention, the declaration:

struct tfsdev alt_tfsdevtbl [TFSDEVTOT] = { [0 ... (TFSDEVTOT-1)] = { (char *)0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff } };

is basically telling the compiler to statically initialize all elements in alt_tfsdevtbl (from 0 to (TFSDEVTOT-1)) to the defaults:

{ (char *)0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff }

(If I am correct, that means that the tfsdev structure contains 7 "elements/fields").

To make a similar declaration in Codewarrior you must do the following:

struct tfsdev alt_tfsdevtbl [TFSDEVTOT] = { { (char *)0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff,

0xffffffff, 0xffffffff }, //0 { (char *)0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff }, //1 { (char *)0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff }, //2 ... { (char *)0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff }, // TFSDEVTOT-2 { (char *)0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff, 0xffffffff }, // TFSDEVTOT-1 };

If TFSDEVTOT is too big, try to encapsulate the initialization in a function:

for ( i = 0; i < TFSDEVTOT; i++ ) { alt_tfsdevtbl [i].xxxxxxx = 0xffffffff; alt_tfsdevtbl [i].xxxxxxx = 0xffffffff; ... OR

memset ( &alt_tfsdevtbl[i], 0xFF, sizeof ( struct tfsdevtbl )); }

If you read the GCC manual, you'll note that the construct you're using is a GCC extension. Cygwin has nothing to do with this feature.
