Hi. Just a little thing I found... I was trying my first build with Olins environment and code setup for a PIC18F1320. Now, I first run MPASMWIN with the "/c-" switch ("not case sensitive") I then had this problems with the p18f1320.inc file : Error[115] C:\PROGRAM\MPLAB IDE\MCHIP_TOOLS\P18F1320.INC 66 : Duplicate label ("CLRW" or redefining symbol that cannot be redefined) on these lines in the p18f1320inc file : #define clrw clrf WREG ; PIC16Cxxx code substitution #define CLRW CLRF WREG ; PIC16Cxxx code substitution Seems reasonable, I don't think you can build anything using any environment using this include file and the "/c-" switch, or ? I then changed the switch to "/c+" to overcome this. The clrw/CLRW problems went away, but now I get problems with the detection of the processor type, since Olins code looks for " ifdef __18f1320" and obviously a symbol called "__18F1320" is defined someware. Is this symbol created by the MPASMWIN ? Obviously I'll just have to make a few changes here and there to get this running, but I thought you'd be interested anyway. *OR* have I done some major blunder here ?
