undefined identifier byte
PostPosted: Mon Jan 10, 2011 11:15 am     Reply with quote
I'm using the ccs built-in sqrt to calculate the square root of a float. It gives me a linker error that there is an undefined identifier BYTE. Since it's a builtin I wouldn't expect this to be an issue. Also I have properly included the math.h library. This problem occurs in the sqrt function. I'm not really sure how to fix it. Any suggestions or has anyone had similar problems?

BYTE isn't a CCS C built-in data type. You have to define it.

It's in the .h file for every PIC.
