Hi

I have never used the SDCC-compilier but if the makefile looks the same as in the UNIX/LINUX than you may try something like this

all: myfile1.o myfile2.0
gcc -Wall -o myprog myfile1.o myfile2.o
myfile1.0: myfile1.c myfile1.h
gcc -Wall -c myfile1.c
myfile2.0: myfile2.c myfile2.h
gcc -Wall -c myfile2.c

Creates a exe-file myprog.exe from the obj files myfile1 and myfile2
