RE: [Sdcc-user] compiler warnings

[<M.v...@ca...>]

The problem with your -L... line is that it's wrong. The correct path is
c:\sdcc\lib\large (for large model) and c:\sdcc\lib\small for small model.

I put it all in my makefile, which is as follows (requires gnu make, which
you can get off the net, precompiled for Win32 - I put it in the c:\sdcc\bin
directory):

======8><== BEGIN MAKEFILE ========================

# Makefile for ADuC812 project
#
# v 1.0 - initial version - 2001-09-11 MvdW
# 

MODEL=    large

ifeq ($(MODEL), large)
    STACK=	  --stack-after-data 
else
    STACK=	  --stack-after-data
endif

CFLAGS=   -I c:/apps/sdcc/include -L c:/apps/sdcc/lib/$(MODEL) \
--verbose --nooverlay --model-$(MODEL) $(STACK)
CFILES=   main.c serial.c
RELFILES= main.rel serial.rel
CC=		  sdcc

all:	main.hex 
  
main.hex:	main.ihx 
	packihx main.ihx > main.hex
	cat main.map | grep 'bytes'

main.ihx:	$(RELFILES)
	$(CC) --version
	$(CC) $(CFLAGS) $(RELFILES)

%.rel:		%.c %.h ADuC812.h
	$(CC) --version
	$(CC) $(CFLAGS) -c $<

force:      clean all
		
	
clean:
	rm -f $(RELFILES) main.ihx main.hex

====== 8>< ======== END MAKEFILE ============================

This isn't the simplest makefile there is, and there are some redundant
parts (from when I was trying various things), but it works for me.

You might want to get some help on makefiles (http://www.gnu.org is a good
place to start) if you want to learn more about them. It beats a batch file
hands down.
