I have touble when including files with makefile for a stm32f4xx - gnu-make

Question

I'am starting using Linux and I have some trouble using some stm32f4 libraries for my project gcc-testing.
All the CMSIS programs needed are inside the STM32F4_Discovery_FW_V1.1.0 and the project is arranged like this:
~
|__
| |
| STM32F4XX
| |
src STM32F4_Discovery_FW_V1.1.0
|
ggc-testing
|
makefile
main.c
stm32f4xx_config.h
stm32_flash.ld
system_stm32f4xx.c
The main.c and the system_stm32f4xx.c use the stm32f4xx.h file that is inside the STM32F4_Discovery_FW_V1.1.0/Libraries/CMSIS/ST/STM32F4xx/Include
The error I get from the terminal is:
Make file console error
My make file:
PROJ_NAME=main
STM_DIR=~/STM32F4XX/STM32F4-Discovery_FW_V1.1.0
STM_SRC = $(STM_DIR)/Libraries/STM32F4xx_StdPeriph_Driver/src
vpath %.c $(STM_SRC)
SRCS = main.c
SRCS += system_stm32f4xx.c
SRCS += $(STM_DIR)/Libraries/CMSIS/ST/STM32F4xx/Source/Templates/TrueSTUDIO/startup_stm32f4xx.s
INC_DIRS = $(STM_DIR)/Utilities/STM32F4-Discovery
INC_DIRS += $(STM_DIR)/Libraries/CMSIS/Include
INC_DIRS += $(STM_DIR)/Libraries/CMSIS/ST/STM32F4xx/Include

LFLAGS = -Tstm32_flash.ld
.PHONY: $(PROJ_NAME)
$(PROJ_NAME): $(PROJ_NAME).elf
$(PROJ_NAME).elf: $(SRCS)
$(CC) $(INCLUDE) $(DEFS) $(CFLAGS) $(LFLAGS) $^ -o $#
$(OBJCOPY) -O ihex $(PROJ_NAME).elf $(PROJ_NAME).hex
$(OBJCOPY) -O binary $(PROJ_NAME).elf $(PROJ_NAME).bin
clean:
rm -f *.o $(PROJ_NAME).elf $(PROJ_NAME).hex $(PROJ_NAME).bin
# Flash the STM32F4
flash:
st-flash write $(PROJ_NAME).bin 0x8000000
.PHONY: debug
debug:
# before you start gdb, you must start st-util
$(GDB) $(PROJ_NAME).elf
Hope enyne can help with this.

After gnu make generates a cmd-line (eg gcc), use of a ~ would rely on make executing a shell and the shell expanding an arg with a leading unquoted ~. Based on your line with $(addprefix, try adding a space between -I and ,$(INC_DIRS)
However, the overhead from executing a shell can be undesirable and the extra exec is often easy to avoid; for this case, replace ~ with $(HOME)
Example Makefile :
SUBDIR := some/incdir
TILDE_SUBDIR := ~/$(SUBDIR)
NOT_DELIM := $(addprefix -I,$(TILDE_SUBDIR))
DELIM_INC := $(addprefix -I ,$(TILDE_SUBDIR))
HOME_SUBDIR := $(HOME)/$(SUBDIR)
PHONY: all
all:
#echo NOT_DELIM $(NOT_DELIM)
#echo DELIM_INC $(DELIM_INC)
#echo HOME_SUBDIR $(HOME_SUBDIR)
Output :
NOT_DELIM -I~/some/incdir
DELIM_INC -I /home/user1/some/incdir
HOME_SUBDIR /home/user1/some/incdir
