Makefile for building multiple programs
I have the following part of a makefile and want to simplify it
using rules rather than having to code the same two blocks
when I need ti build another program.

An having difficulty doing it

Code:
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 together

Code:
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
all: $(TARGETS)

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.

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
is not printing anything when building the targets.

Code:
# 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?

---------- Post updated at 01:32 PM ---------- Previous update was at 01:26 PM ----------

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
Code:
make all

the object files are removed. Cannot figure out how make issues a remove at the end


Code:
# Fortran linker
FLINKER = gfortran

# Fortran compiler
FCOMPILER = gfortran

RM_OPT = --preserve-root --verbose

MAINDIR = ../../../libs/main

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)))

.PHONY : default
default : help

all : $(TARGETS)

$(BINDIR)/% : $(OBJDIR)/%.o
    $(FCOMPILER) -o $@ $^

# COMPILE MISC MAIN PROGRAMS
