Makefile noob

Trying to port a library ( or at least functionality ) from PC GCC to Propgcc. The code compiles on the PC using this makefile:


mdc_test: mdc_test.c mdc_decode.o mdc_encode.o
cc -g -o mdc_test mdc_test.c mdc_decode.o mdc_encode.o
./mdc_test

mdc_decode.o: mdc_decode.c mdc_decode.h mdc_common.c
cc -c mdc_decode.c

mdc_encode.o: mdc_encode.c mdc_encode.h mdc_common.c
cc -c mdc_encode.c

clean:
rm -f mdc_decode.o mdc_encode.o mdc_test

This looks like just a straight forward multifile Make, any thoughts on how this would look for PropGCC? My last dealings with makefiles was in the heydays of the Amiga I have looked at the samples in the demo directory but quickly get lost in the maze of switches. The code will have to be highly modified to do anything useful on the Prop but I first have to get over the hurdle of getting my head around a multifile project.

Try something like this:

CC=propeller-elf-gcc
CFLAGS=-mcmm -Os -Wall

mdc_test: mdc_test.c mdc_decode.o mdc_encode.o
   $(CC) $(CFLAGS) -o mdc_test.elf mdc_test.c mdc_decode.o mdc_encode.o
   propeller-load mdc_test.elf -r -t

mdc_decode.o: mdc_decode.c mdc_decode.h mdc_common.c
   $(CC) $(CFLAGS)  -c mdc_decode.c

mdc_encode.o: mdc_encode.c mdc_encode.h mdc_common.c
   $(CC) $(CFLAGS)  -c mdc_encode.c

clean:
   rm -f mdc_decode.o mdc_encode.o mdc_test.elf

Note that the spaces at the beginnings of the lines within the rules should be actual hardware tab characters.

Thanks David! Compiles with just a couple of warnings. Makes me wish I had a Quickstart with me.

Glad it worked for you!
