Struct assignment?
PostPosted: Sun Dec 12, 2010 8:30 am     Reply with quote
Why is it not legal in CCS to assign a const struct with values from the struct itself?
All the assign and calculation is done at compile time.

The problem is this statement:
EEPos.Data+sizeof(EEData),//EE phone1


Code:
char PhoneN[20];
struct{
 int8 Value0;
 int8 Value1;
 int8 Value2;
 char Pass[11];
}EEData;


Code:
//Position in EEprom
struct{
 int8 Data;
 int8 ph1;
 int8 ph2;
 int8 ph3;
}const EEPos={
    10, //Assign 10 byte to? and then EE Data position
    EEPos.Data+sizeof(EEData),//EE phone1
    EEPos.ph1+ sizeof(phoneN),//EE phone2
    EEPos.ph2+ sizeof(phoneN) //EE phone3
    };

This was just discussed a few days ago: http://www.ccsinfo.com/forum/viewtopic.php?t=44203. As to why, ask CCS support I guess. In my opinion you should be able to do that, but if you can't - you can't. You can ask CCS to include that in a future release as a fix, though.

hmm it's not the same q. If I just use a number it work. I use a number for now. It was more clear if I use EEPos.Data+sizeof(EEData), but CCS dont like this:"EEPos.Data"
