Hello all, I have the following situation and error message that I'm not quite able to wrap my head around. I have a module, let's call it table.c that has something like the following. code const entry_type table[] = {...}; code const unsigned int tablesize = sizeof(table); Of course, ... is replaced by a bunch of table data. In another module, call it access.c, I have the following: extern code const entry_type table[]; extern code const unsigned int tablesize; code const unsigned int entrysize = sizeof(entry_type); code const unsigned int numentries = tablesize/entrysize; I receive an error C247 when trying to compile the line where I calculate numentries. Oddly enough, it doesn't complain about calculating entrysize, so it's good with making that a code constant. Nor does it have a problem in table.c creating the tablesize code constant. I'm not sure why then it wouldn't think that numentries could be a code constant. I've also tried making sure that table.c is compiled before access.c (just a blind attempt) and that didn't help. Any help would be greatly appreciated. Best Regards, Jay Daniel
