I have a multi-boot machine (DR-DOS, Win95, WinNT, and Linux). I need
to build a Linux version of some software that I normally edit and
build using DJGPP under NT 4.0. As a result, I would like to use a
makefile to assist in the constant conversion of files from Dos to
Unix format, which will execute the dos2unix.com file that I
downloaded for that purpose.

So, I created a "Unix" subdirectory under the source code directory,
and then defined a Makefile that will copy *.c and *.h files from the
parent to the Unix subdirectory, then run Dos2unix on
them. (Dos2unix.com operates in place, using the same file for input
and output.)

However, when I execute the Makefile with "make all", I get a message
that there is nothing to do. If I delete foo.h from the Unix
directory, then re-make, I get the same message --- the target does
not even exist, yet "there is nothing to make" ! I guess there is
something simple that I am missing about make. I am using the latest
DJGPP gnu make 3.79.1. Here is the Makefile, which resides in the Unix
subdirectory:

.h.h:
		  cp $< $@
		  dos2unix $@

.c.c:
		  cp $< $@
		  dos2unix $@

ROOT_DIR    = /research/cache/findout
MD_DIR      = ${ROOT_DIR}/intelP6
UNIX_DIR    = ${MD_DIR}/unix

UNIXSRCS =   ${UNIX_DIR}/dosparms.c ${UNIX_DIR}/instparm.c \
             $(UNIX_DIR)/pmpcl.c \
             $(UNIX_DIR)/pmpapi.c \
             $(UNIX_DIR)/inst1kb.c ${UNIX_DIR}/regress.c \
             $(UNIX_DIR)/inst4kb.c $(UNIX_DIR)/inst1kbm.c \
             $(UNIX_DIR)/inst4kbm.c ${UNIX_DIR}/genmacro.c

UNIXHDRS =   ${UNIX_DIR}/dosparms.h ${UNIX_DIR}/instparm.h \
             $(UNIX_DIR)/pmpcl.h \
             $(UNIX_DIR)/pmpapi.h \
             ${UNIX_DIR}/regress.h \
             $(UNIX_DIR)/bool.h ${UNIX_DIR}/pm.h

all:       sources headers

sources:   ${UNIXSRCS}

headers:   ${UNIXHDRS}

${UNIX_DIR}/dosparms.h : ${ROOT_DIR}/dosparms.h

${UNIX_DIR}/dosparms.c : ${ROOT_DIR}/dosparms.c

${UNIX_DIR}/instparm.h : ${ROOT_DIR}/instparm.h

${UNIX_DIR}/instparm.c : ${ROOT_DIR}/instparm.c

${UNIX_DIR}/inst1kb.c : ${ROOT_DIR}/inst1kb.c

${UNIX_DIR}/inst4kb.c : ${ROOT_DIR}/inst4kb.c

${UNIX_DIR}/inst4kbm.c : ${ROOT_DIR}/inst4kbm.c

${UNIX_DIR}/genmacro.c : ${ROOT_DIR}/genmacro.c

${UNIX_DIR}/pm.h : ${ROOT_DIR}/pm.h

${UNIX_DIR}/bool.h : ${ROOT_DIR}/bool.h

${UNIX_DIR}/pmpcl.c : ${ROOT_DIR}/pmpcl.c

${UNIX_DIR}/pmpcl.h : ${ROOT_DIR}/pmpcl.h

${UNIX_DIR}/pmpapi.c : ${ROOT_DIR}/pmpapi.c

${UNIX_DIR}/pmpapi.h : ${ROOT_DIR}/pmpapi.h

${UNIX_DIR}/regress.c : ${ROOT_DIR}/regress.c

${UNIX_DIR}/regress.h : ${ROOT_DIR}/regress.h

Any obvious problems here?

Thanks for the help.
