Presumably one of those expressions isn't a compile time one.

Add // in front of each. The error should go away. Then remove the //s 
one by on until it comes back. (Watch out for a trailing comma on the 
last uncommented line causing a syntax error.)

(Maybe uartTivarRB isn't a flat array, but a pointer?)
