Need help with CCS PIC C compiler

Hello,

I just bought a copy of the CCS PCH compiler to complete a job. I've previously used the Microchip C18 compiler, but my copy is old and does not support the processor I am using.

I am attempting to port code compiled with the Keil C51 / uVision system, that has run successfully on another design of mine using an 8051 variant. It's pretty much ANSI C.

I get errors with a structure declaration:

23 typedef union
24 {
25 int16 value;
26 unsigned char byte[2];
27 }W_UNION;

*** Error 28 "C:\C K Enterprises\Minco\MLS\Code\minco.h" Line 26(19,20): Expecting an identifier
*** Error 43 "C:\C K Enterprises\Minco\MLS\Code\minco.h" Line 26(20,21): Expecting a declaration

*** Error 48 "C:\C K Enterprises\Minco\MLS\Code\minco.h" Line 27(2,9): Expecting a (

This code compiles fine under C51, and BoostC (which I can't use as there is no printf() function).

I hope it's not a case of CCS not allowing arrays or such.
Any ideas?

I would guess that "byte" is reserved. Try changing the name.

Mike.

That did it!

'byte' evidently was reserved, but as CCS does not include an index in their reference manual, I don't see where it might be documented.

#BYTE is defined to force a C variable to a fixed address in memory, though.

Thanks for the tip. Onward to the next error...
