In my makefile I want to include some other makefile depending on a variable in a for loop, Is it possible.
Top Makefile :
CC = gcc
CFLAGS = -O0 -g3 -W -Wall -pedantic
LDFLAGS =
DEFINES =
PROJECT = proj
INCLUDES =
SOURCES =
TEMP_PATH := $(PROJECT)
include $(TEMP_PATH)/Makefile
$(for blocks in $(BLOCKS); do \
include $$(blocks)/Makefile; \
done)
all : $(PROJECT).exe
$(PROJECT).exe :
$(CC) $(CFLAGS) $(LDFLAGS) $(DEFINES) $(INCLUDES) $(SOURCES) -o $#
clean :
rm -rf *.exe
proj/Makefile :
CC = gcc
CFLAGS = -O0 -g3 -W -Wall -pedantic
LDFLAGS =
DEFINES =
BLOCKS := std_communication
INCLUDES := $(INCLUDES) -I $(TEMP_PATH)/Utils
INCLUDES := $(INCLUDES) -I $(TEMP_PATH)/Communication
SOURCES := $(SOURCES) $(wildcard $(TEMP_PATH)/Utils/*.c)
SOURCES := $(SOURCES) $(wildcard $(TEMP_PATH)/Communication/*.c)
SOURCES := $(SOURCES) $(wildcard $(TEMP_PATH)/main.c)
The for loop syntax seems to be wrong outside of loop.
You cannot write it like that, but you can just write:
include $(addsuffix /Makefile,$(BLOCKS))

Soo this si my makefile .
I want to find all .cpp files and compile.
Without their full name specified in CPP_FILE
Example :
CPP_FILE : test.cpp main.cpp slow.cpp scan.cpp
I want something like CPP_FILE = *.cpp
It is this possible?
Make provides a wildcard function for this very purpose.
CPP_FILE = $(wildcard my_dir/*.cpp)
I'm devloping application on nRf51 for that i'm using...
SDK : nRF51_SDK_7.2.0_cf547b5
Tool chain : GNU tools arm Embedded [arm-none-eabi version 4.9.3]
Dev Board : PCA10028(nRF51 DK)
I'm using following example.
C:\nRF51_SDK_7.2.0_cf547b5\examples\peripheral\blinky
When i compile this example using makefile at location C:\nRF51_SDK_7.2.0_cf547b5\examples\peripheral\blinky\pca10028\blank\armgcc
it compiles well and also generate binary/hex.
I want to move this blinky example to D Drive. So now my example is at location D:\blinky.
I'm compiling this example using makefile at location D:\blinky\pca10028\blank\armgcc

Any solution on this?
Thank you.
It seems that your absolute source file paths are incorrect :
$(TOOLCHAIN_PATH)/components/toolchain/system_nrf51.c
$(TOOLCHAIN_PATH)/components/drivers_nrf/hal/nrf_delay.c
$(TOOLCHAIN_PATH)/components/toolchain/gcc/gcc_startup_nrf51.s
preventing the corresponding objects from being built.
Please update TOOLCHAIN_PATH - or use another variable - to reflect your new D: location.
I'm devloping application on nRf51 for that i'm using:
Compiler: GNU ARM C cross compiler[gcc]
SDK: nRF51_SDK_7.2.0_cf547b5
Tool chain: GNU tools arm Embedded [arm-none-eabi version 4.9.3]
I'm trying to create a makefile in which all source file directories and object directories are different. My makefile needs rules to target *.o files whose source files are on different directories than the project directory. How should I modify the makefile, so that it can compile a C source file from a different directory?
after executing make in cmd.exe, I get:
rm -rf _build
makefile
mkdir _build

I am working on programming a nrf51822 evaluation board(This one). I have been looking at this site to program it and have gotten the blinking program to work.
I want to modify the makefile provided on the site previously mentioned, such that when I go along I pretty much only have to add to the list of files to compile. Below is what I have been trying to get to work, but I am not very good with makefiles.

This at least works for now :)
I have to create different *.o files from a same set of *.c using various CFLAGS. I wanted to use patsubst to generate different *.o files from same *.c. I am doing something wrong the following statement, please help (I want to generate one set of object files having ($<)_O0.o and the other ($<)_O2.o from the same set of c source files):
$(CC) $(CFLAGS_02) -c $< -o $(patsubst %.c,%_O2.o,$<)
Thanks
Use patsubst to make lists of the objects that you want to build, and then use separate rules for each type of build.
Something like this:
SRC_FILES = source1.c source2.c
OBJ_FILES_O0 = $(patsubst %.c,%_O0.o,$(SRC_FILES))
OBJ_FILES_O2 = $(patsubst %.c,%_O2.o,$(SRC_FILES))
CFLAGS_O0 := -O0
CFLAGS_O2 := -O2
all: $(OBJ_FILES_O0) $(OBJ_FILES_O2)
$(OBJ_FILES_O0): %_O0.o: %.c
$(CC) $(CFLAGS_O0) -c $< -o $#
$(OBJ_FILES_O2): %_O2.o: %.c
$(CC) $(CFLAGS_O2) -c $< -o $#
You can also use wild cards to specify all files in the directory.
eg:
#Generic Makefile.
CC := g++
LD := g++
CFLAGS := -c
LDFLAGS := -L<path to lib> -l<libname> \
-L<path to lib> -l>libname> \
......................
ifeq (${TARGETARCH}, debug)
CFLAGS += -g -O0
elif
CFLAGS += -O4 -DNDEBUG
SRCFILES := $(wildcard *.cpp)
OBJFILES := $(patsubst %.cpp, %.o, ${SRCFILES})
all: main
main: ${OBJFILES}
#echo "[Linking]"$#
${LD} ${LDFLAGS} ${OBJFILES}
%.o: %.cpp
#echo "[Compiling]"$#
${CC} ${CFLAGS} $^ -o $#
