Hi using the below make file how can I create all the object files in to a directory obj.
May be this question is very simple but no idea how to do it ?

There are lots and lots of answers to this question available already. Did you look?
Try:
OBJECTFILES = $(patsubst %.cpp,obj/%.o,$(SOURCEFILES))
...
obj/%.o : %.cpp
$(CXX) $(CPPFLAGS) $(CXXFLAGS) -c -o $# $<

I've been trying to get my Raspberry Pi 4 OS (not Linux or anything, I'm making an OS from scratch) to work.
The Makefile has this error when I use the command "make":
rm -rf objects
rm -rf SuperPiOS.elf
rm SuperPiOS.img
rm: cannot remove 'SuperPiOS.img': No such file or directory
make: *** [Makefile:110: clean] Error 1
I can't figure out why it wouldn't work though.

You have two problems. The most obvious one is that this command:
rm SuperPiOS.img
is failing because that's how the rm program is defined: if the file you ask it to delete doesn't exist then rm will fail. If you don't want that to happen, add the -f option:
rm -f SuperPiOS.img
Now if the file doesn't exist, rm will silently succeed. You can examine the man pages for the rm program.
However, the higher level question you are probably asking is, why when I run make is it running the clean rule?
That's because make, if you don't specify what to build on the command line, always builds the first explicit target. In this makefile the first explicit target you defined is clean, so that's what's built. This is almost certainly not what you want. You should figure out what target you want to build when you run make with no arguments and put the rule for that target as the first explicit target in your makefile.
Other than this rule it normally doesn't matter much what order rules come in (if you have multiple pattern rules that could all build the same target, for example multiple pattern rules to build %.o, then order can matter there).
I'm trying to use GCC (linux) with a makefile to compile my project.
I get the following error
"No rule to make target 'output/src/main.o', needed by 'test'. Stop."
This is the makefile:
COMPILE_PREX ?=
CC = $(COMPILE_PREX)gcc
SOURCE = $(wildcard src/*.c)
OBJS = $(addprefix ./output/, $(patsubst %.c, %.o, $(SOURCE)))
INCLUDES = -I ./src
CFLAGS += -O2 -Wall -g
LDFLAGS += -lpthread
TARGET = test
$(TARGET): $(OBJS)
$(CC) $(OBJS) $(LDFLAGS) -o $(TARGET)
%.o: %.c
#mkdir -p ./output
$(CC) $(CFLAGS) $(INCLUDES) -o $(addprefix ./output/, $#) -c $<
clean:
rm -rf ./output
This should work. Note the use of mkdir $(#D) to create output directories as needed.
COMPILE_PREX ?=
CC = $(COMPILE_PREX)gcc

$(CC) $(OBJS) $(LDFLAGS) -o $(TARGET)
output/%.o: %.c
#mkdir -p $(#D)

Running it here with make clean test:
rm -rf output
gcc -O2 -Wall -g -I src -o output/src/hello.o -c src/hello.c
gcc output/src/hello.o -lpthread -o test
I have a makefile, that I edited so that object files should go to a separate directory.
I edited the makefile and it is now doing what I wanted to, but during linker stage it is not working as expected because I am doing something wrong.
I have a sources file and makefile as shown below:

The output command picks only the first object file from correct directory under build/objs.
Rest object file path doesn't have build/objs/.
Please anyone help me resolve this issue?
You are violating Mad Scientist's second rule of makefiles, and inviting more problems than you know.
Look at these rules (simplified):
$(TARGET).elf: $(OBJS)
$(LD) $(BUILD_DIR)/$^ -o $#
$(OBJS): %.o: %.c
$(CC) -c $< -o $(BUILD_DIR)/$#
Suppose the build directory is build/ and the object file is build/foo.o. The target of the second rule is foo.o, but what it actually builds is build/foo.o. Likewise, the first rule claims foo.o as a prerequisite, but it doesn't actually use foo.o, it uses build/foo.o These two errors cancel each other out, in a sense; Make succeeds in building the main target. But as you have found, it has trouble if there is more than one object file, because if the prerequisite list is foo.o bar.o, then
`$(BUILD_DIR)/$^`
expands to
build/foo.o bar.o
Also, Make will run the second rule even if build/foo.o exists and is up to date, and will fail to run it if foo.o exists. The target of a non-PHONY rule should be the name of the file it builds, and a non-PHONY prerequisite should be the name of a file whose existence is relevant:
$(TARGET).elf: $(BUILD_OBJS)
$(LD) $^ -o $#
$(BUILD_OBJS): $(BUILD_DIR)/%.o: %.c
$(CC) -c $< -o $#

I have tried too much to place auto-generated files (e.g. object files) in a separate directory(OBJDIR), but I did not find any solution.
I referred to this tutorial, but it is not suitable for my Makefile.
Could you please help me?
Let's take this in small steps.
You already have a rule for building object files:
.c.o:
$(CC) $(CFLAGS) $(INCLUDES) -c $< -o $#
Which can be written out as:
%.o: %.c
$(CC) $(CFLAGS) $(INCLUDES) -c $< -o $#
This will use ../LwMesh/phy/at86rf212/src/phy.c to build ../LwMesh/phy/at86rf212/src/phy.c. But imagine for a moment that phy.c were in the working directory. Then Make could use that rule to build phy.o from phy.c. In that case we could make a small change in the rule:
$(OBJDIR)/%.o: %.c
$(CC) $(CFLAGS) $(INCLUDES) -c $< -o $#
and Make would build obj/phy.o.
How do we tell Make where to find phy.c? There are two good ways. One is using vpath:
vpath %.c ../LwMesh/phy/at86rf212/src
After we confirm that this works, we can add other directories for other sets of objects (such as PHY and SYS):
vpath %.c ../LwMesh/phy/at86rf212/src ../LwMesh/hal/atmega1281/src ../LwMesh/sys/src ...
Now all we have to do is construct the lists of objects correctly:
PHY_OBJS = phy.o
HAL_OBJS = hal.o halPhy.o halTimer.o
SYS_OBJS = sys.o sysEncrypt.o sysTimer.o
...
Once this much is working correctly, further refinements are possible.

I know this question have been up multiple times but I can't seem to find my problem anyway.
The object and dependency files are created in their own folders. But it seems that they are not used when recompiling. What have I done wrong?
I have followed http://make.mad-scientist.net/papers/advanced-auto-dependency-generation/#combine for the generation of dependency files.
