That'll work just fine for simple projects but once you get more source
files it may get harder to manage. also adding a .PHONY: line is helpful
just incase there is a file named clean.
This may be a better template makefile for future projects.
%.o matches any argument to make with a .o ending.
$^ matches the entire dependencies list
$< matches the first file in the dependencies list
$@ matches the target.

NAME=MiniRF.elf
CPU = msp430x1121
DEPS = tx.inc sw1const.inc
CC = msp430-gcc
COPT = -mmcu=${CPU} -O2 -Wall -g
.PHONY: clean
MiniRF.elf : tx.o int1switch.o
${CC} -mmcu=${CPU} -Wall -O2 -o $@ $^
%.o : %.c %.h ${DEPS}
${CC} ${COPT} -c $<
clean:
rm -f ${NAME} ${NAME}.a43 ${NAME}.lst ${NAME}.ini *.o

Subject: Re: [Mspgcc-users] compiling multiple source files
Thanks to all who helped me with the make file information.
I managd to cobble together a crude makefile implementation which produced a
valid *.elf file for GDB-Insight.
Here it is:
**********************************
NAME=MiniRF.elf
CPU = msp430x1121
CC = msp430-gcc
COPT = -mmcu=${CPU} -O2 -Wall -g
MiniRF.elf : tx.o int1switch.o
${CC} -mmcu=${CPU} -Wall -O2 -o MiniRF.elf tx.o int1switch.o
tx.o : tx.c tx.h tx.inc sw1const.inc
${CC} ${COPT} -c tx.c
int1switch.o : int1switch.c int1switch.h tx.inc sw1const.inc
${CC} ${COPT} -c int1switch.c
clean:
rm -f ${NAME} ${NAME}.a43 ${NAME}.lst ${NAME}.ini *.o
**************************************************

Thanks,
Mark
