I don't success in compiling a multiple file project :
I mean that I would want to have a macro.inc (with macro functions) file and main.asm file which contain my code.
I put the linker file into my project and add the macro.inc in the header file.
I also put in my code the macro.inc with a include directive.
Do you know if I must choose "Generate relocatable code" or "generate absolute code" ?
when I tried the first one, it give me this error :
MPLINK 4.39, Linker

Copyright (c) 1998-2011 Microchip Technology Inc.
Error - file './COMPA.o', section '.org_5', Symbol '_.org_5_01F6' is not word-aligned.
It can not be used as the target of a call or goto instruction.
Errors : 1
for the absolute code :

Do you know why it can't compile it ?
here is .asm code :
and the macro.inc header file :
