hi alan,

is your path correct ? are you able to exec msp430-ld directly (from your
IDE (where you call gcc))
>>Otherwise in the GCC litterature, the word makefile is used a lot. How do
I go about creating one and what should I put in it?
about the makefile - the next few lines show a simple makefile exmaples:
.SUFFIXES: # Delete the default suffixes
NAME=outputname.elf
CC=msp430-gcc
CPU=msp430x427
ASMOPT = -mmcu=${CPU}
CFLAGS = -mmcu=${CPU} -O2 -Wall -g
OBJECTS = Transmitter_31_12.o flash_31_12.o sd16_31_12.o
port1_interrupt_31_12.o
all: ${NAME}
%.o: %.c
# $(CC) ${CFLAGS} -S -dp $<
$(CC) ${CFLAGS} -c $<
${NAME}: ${OBJECTS}
$(CC) -mmcu=${CPU} -o $@ $^
msp430-objcopy -O ihex $@ [email protected]
# msp430-objdump -DS ${NAME} >${NAME}.lst
msp430-size ${NAME}
.PHONY: clean
clean:
del *.o ${NAME} ${NAME}.lst ${NAME}.hex
#automatic collection of dependencies in the source files.
#it's only updated the first time, after that it must be done maually
#with "make depend"
#the dependecies are included from a separate file:
-include dependencies.in
#target to update the file, it's removed first
depend: rmdepend dependencies.in
#remove the file
rmdepend:
rm -f dependencies.in
#build the file that contains the dependencies. no deps in this rule.
#if there were deps it would be rebuilt every chnage, which is unneded:
dependencies.in:
$(CC) -MM ${CFLAGS} $(patsubst %.o,%.c,$(OBJECTS)) >$@
good luck,
matthias

Betreff: [Mspgcc-users] installing gcc compiler and debugger
Dear All,
This morning, I downloaded the gcc compiler of the sourceforge web site. I
then installed it on my pc. Once I did this, I realised that it didn't have
a GUI, so I also downloaded SciTE.
I want to be able to use the MSP430 USB Debug-Interface to download my code.
I wrote C code for my MSP application with an IAR compiler and am trying to
recompile the code with GCC. My code is made up for 4 C files. I changed the
declaration of all my interrupt function prototypes so that it matchs what
it says in the GCC manual. I also included the signal.h header file.
In SciTE I type the following command to compile my code:
>msp430-gcc -mmcu=msp430x427 -g -Os -o Transmitter_31_12.c flash_31_12.c
sd16_31_12.c port1_interrupt_31_12.c
port1_interrupt_31_12.c:17: warning: built-in function `index' declared as
non-function
port1_interrupt_31_12.c: In function `intPort1':
port1_interrupt_31_12.c:1381: warning: comparison is always false due to
limited range of data type
msp430-gcc: installation problem, cannot exec `msp430-ld': No such file or
directory
>Exit code: 1 Time: 0.662
As you can see, there is some error to do with `msp430-ld'. How do I solve
this?
Otherwise in the GCC litterature, the word makefile is used a lot. How do I
go about creating one and what should I put in it?
Could somebody possibly talk me through, how to create a GCC project,
compile the code, download the file to the MSP and then debug the code using
breakpoints etc?
Thanks in advance for your help,
Regards,
Alan
