I have the following part of a makefile and want to simplify it
An having difficulty doing it
all: 1dvel2 1dvel 2dvel
#--------------------------------------------------------------------
1dvel2 : 1dvel2.o $(MISC_MAINDIR)/ray.par
$(FCOMPILER) -o $(BINDIR)/1dvel2 $(OBJDIR)/1dvel2.o
1dvel2.o : $(MISC_MAINDIR)/1dvel2.f
$(FCOMPILER) -c $<
mv *.o $(OBJDIR)
#--------------------------------------------------------------------
1dvel : 1dvel.o $(MISC_MAINDIR)/ray.par
$(FCOMPILER) -o $(BINDIR)/1dvel $(OBJDIR)/1dvel.o
1dvel.o : $(MISC_MAINDIR)/1dvel.f
$(FCOMPILER) -c $<
mv *.o $(OBJDIR)
#--------------------------------------------------------------------
2dvel : 2dvel.o $(MISC_MAINDIR)/ray.par
$(FCOMPILER) -o $(BINDIR)/2dvel $(OBJDIR)/2dvel.o
2dvel.o : $(MISC_MAINDIR)/2dvel.f
$(FCOMPILER) -c $<
mv *.o $(OBJDIR)

I am now doing like this. Now the problem in putting the separate executable
TARGETS = $(BINDIR)/1dvel2 $(BINDIR)/1dvel $(BINDIR)/2dvel
all: $(TARGETS)
$(BINDIR)/1dvel2 : $(OBJDIR)/1dvel2.o $(MISC_MAINDIR)/ray.par
$(FCOMPILER) -o $@ $<
$(BINDIR)/1dvel : $(OBJDIR)/1dvel.o $(MISC_MAINDIR)/ray.par
$(FCOMPILER) -o $@ $<
$(BINDIR)/2dvel : $(OBJDIR)/2dvel.o $(MISC_MAINDIR)/ray.par
$(FCOMPILER) -o $@ $<
#--------------------------------------------------------------------
$(OBJDIR)/%.o : $(MISC_MAINDIR)/%.f
$(FCOMPILER) -c $<
mv *.o $(OBJDIR)
Why do you want the following line?
TARGETS = $(BINDIR)/1dvel2 $(BINDIR)/1dvel $(BINDIR)/2dvel
Do you wanna create a new executable with these three binaries?

Why are you moving the object files? If you do, make will always think the object files are missing and force a rebuild.
I think you should place the makefile and source files in the same directory. Let make buidl the programs in that directory. Add a seperate clean target that removes temporary files.
He has heard and ignored this advice before; as with most other problems, he insists on his own unique(tm) solutions.
Make and source files can be in different folders.
I don't understand how the three targets are combined into one.
The problem is that I do not want to combine the targets into one. Now I have another makefile like this. A problem I have is that the makefile
# Fortran linker
FLINKER = gfortran
# Fortran compiler
FCOMPILER = gfortran
MAINDIR = ../../../libs/main
MISC_MAINDIR = $(MAINDIR)/misc
OBJDIR = ../release/obj
BINDIR = ../release/bin
MISC_INCLUDE = $(MISC_MAINDIR)/ray.par
LDFLAGS :=
CFLAGS_INC :=
CFLAGS := -g -Wall $(CFLAGS_INC)
# SOURCE FILES
SRCS := $(wildcard $(MISC_MAINDIR)/*.f)
SRCNAMES := $(notdir $(SRCS))
# OBJECT FILES
OBJS = $(subst .f,.o,$(subst $(MISC_MAINDIR),$(OBJDIR),$(SRCS)))
OBJNAMES := $(patsubst %.f,%,$(notdir $(OBJS)))
# LIST OF MISC EXECUTABLES
TARGETS = $(patsubst %.f,%,$(subst $(MISC_MAINDIR),$(BINDIR),$(SRCS)))
TARGETNAMES := $(patsubst %.f,%,$(notdir $(TARGETS)))
all : $(OBJS) $(TARGETS)
$(TARGETS) :
for T in $(TARGETNAMES) ; do \
$(FCOMPILER) -o $(BINDIR)/$$T $(OBJDIR)/$$T.o ; \
done
$(OBJDIR)/%.o : $(MISC_MAINDIR)/%.f $(MISC_MAINDIR)/ray.par
$(FCOMPILER) -c $<
mv *.o $(OBJDIR)
Ok Ok. So what am I supposed to do as I do not like all object files, makefiles and executables in the same directory. Or is it that that things are done this way?

I think there is a way how to make the compiler to know where the .o files are.

This is the new make file.
I noticed that when I do
make all
the object files are removed. Cannot figure out how make issues a remove at the end

They are there because you put them there. This was a nicely organized project, until you jammed them all into one folder and makefile. I still don't understand why you did that after being shown ways to control them without dumping them in one big pile.
