recompile it. Since discovering the joys of bootstrapping my
programs, I no longer have one big program but many smaller
interconnected ones.
Identify all the files with .for and .f90 extensions
Execute the commands:
'ifort program.for -o program'
'ifort program2.f90 -o program2'
don't think this would help much. Depending on the purpose of the
programs, they have different names. This would mean I would need a
makefile for each subset of programs.
OBJS=crud.o barf.o junk.o
SRCS=crud.c barf.c junk.c
See my other post.
The last 2 lines above come from trying to
create a lowest common denominator makefile.
Since we're talking GNUMAKE here,
Once you have $(SRC)
$(OBJS) is simply:
OBJS:=$(subst .c,.o,$(SRC))
HDRS=thing.h
all: $(OBJS) $(HDRS)
$(CC) $(CFLAGS) -o program $(OBJS)
OBJS: $(SRCS) $(HDRS)
$(CC) $(CFLAGS) -c $*.c
"all" seems to be missing the target "program".
This assumes 1 program and many subs.
I prefer something like:
SRCS:=$(wildcard *.c)
MAINS:=program.c program2.c
SUBS:=$(filter-out $(MAINS),$(SRCS))
Then you need specific rules for the mains
and generic rules for the subs.
Separating the list of subs into a list for
each main can mean that you have to revert to
specific lists.
Writing the makefile is one of the main jobs to do in any compilation project.
It doesn't just happen naturally ;-)
