Hello,

I have been trying to store my suffixed dot o's in a subdirectory using
"mv", but make can only find 2 files in a series of many files!

How can I correct my error(see below)?

Via examples, what other ways would you improve on my makefile?

Thank you,
Christopher Lusardi

P.S.: I am compiling c and c++ files. Occurrences of "..." indicate "etc".

---------------------------------------------------------------------------

#beginning of makefile

#vpath *.o .:/home/clusardi/.objects/
VPATH = .:.objects

MV = /bin/mv

MY_LIB = /home/clusardi

OBJS_DIR = .my_objects

OTHER_SRC = OTHER_SRC

all : edit

OBJS = main.o  \
file1.o \
..

OBJS2 = file_n.o     \
file_np1.o \
..

file1.o: $(OTHER_SRC)/file1.C
CC -c $(OTHER_SRC)/file1.C
$(MV) $@ $(OBJS_DIR)

${OBJS} : ${@:.o=.c}
cc -c  $?
$(MV) $@ $(OBJS_DIR)/$@

edit: $(OBJS) $(OBJS2)
CC $(OBJS_DIR)/$(OBJS) $(OBJS_DIR)/$(OBJS2) -o $@
$(MV) $@ $(MY_LIB)/$@

#end makefile

---------------------------------------------------------------------------
%make

CC -g /home/clusardi/.objects/main.o file1.o ...
/home/clusardi/.objects/file_n.o  file_np1.o     ...  -o edit
ld64: FATAL   9  : I/O error (file1.o): No such file or directory
*** Error code 2 (bu21)

The above line is a problem. OBJS_DIR is a single directory, but OBJS
(and similairly OBJS2) is a list of files, so this expands to:

/home/clusardi/.objects/main.o file1.o ...

instead of what you want:

/home/clusardi/.objects/main.o /home/clusardi/.objects/file1.o ...

since file1.o isn't in the current directory, but instead under
$OBJS_DIR just like main.o, and so you get the error message.

I suspect the "patsub" command could help you convert %.o into
$(OBJS_DIR)/%.o.

If you're still having problems, posting a small, complete example that
demonstrates the problem would be useful.
