I try to use main.cpp with my source code. I think everthing is fine but I get error, I have exactly same makefile with different project I didnt have error. But I open the new project with Cubemx and try to use some cpp settings in makefile so it didint work.
I get below erorr :
collect2: error: ld returned 1 exit status
Makefile:195: recipe for target 'build/stm32f4_FlashflagTest.elf' failed
make: *** [build/stm32f4_FlashflagTest.elf] Error 1
How can I solve this ?
And this is my makefile:

I found the problem
But I dont know why it works corretly. could anybody explain this?
I use the -specs=nosys.specs instead of -specs=nano.specs
I change this line :
LDFLAGS = $(MCU) -specs=nano.specs -u _printf_float -T$(LDSCRIPT) $(LIBDIR) $(LIBS) -Wl,-Map=$(BUILD_DIR)/$(TARGET).map,--cref -Wl,--gc-sections
LDFLAGS += -Wl,--no-wchar-size-warning

Now, the C_SOURCES directory (Core/Src/, etc) contains main.c that I want to ignore (which I have tried to do, with filter-out). I have reimplemented all of it in main.cpp in CXX_SOURCES, i.e. App/Src/, which I want to compile instead.
However, it looks like the automatic dependency generation still finds, compiles and links Core/Src/main.c instead of App/Src/main.cpp. I am very new to makefiles as a whole and am not sure how to handle this. What can I do?
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 am trying to use the makefile for my work related to SPheno. I am on macOS. When I try to use the command "make Model=Scotogenic". it's showing "*** missing separator". I went through lot of forums and added tabs. when I tried to do it again , now it's showing "*** commands commence before first target" . I am using the default textedit in macOS. I am attaching both the code and screenshot. The terminal screenshot

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.

The issue is in line:
$Q $(LD) -Xlinker -Map $(#:.elf=.map) $(LDFLAGS) -T $(LINKER_SCRIPT) $(BUILD_DIR)/$^ -o $#
For which the output is:
arm-none-eabi-gcc -Xlinker -Map demo.map -nostartfiles -specs=nosys.specs -T LPC17xx.ld build/objs/modbus/ascii/mbascii.o modbus/functions/mbfunccoils.o modbus/functions/mbfuncdiag.o modbus/functions/mbfuncdisc.o modbus/functions/mbfuncholding.o modbus/functions/mbfuncinput.o modbus/functions/mbfuncother.o modbus/functions/mbutils.o modbus/port/port.o modbus/port/portevent.o modbus/port/portserial.o modbus/port/porttimer.o modbus/rtu/mbcrc.o modbus/rtu/mbrtu.o modbus/mb.o demo.o startup_LPC17xx.o system_LPC17xx.o -o demo.elf
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 $#
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 $# $<
