两个简单的makefile的实现，编译当前目录下所有的.c文件

在网上找到的一个非常好的makefile文件，可以编译本文件夹下的所有.c文件，之需要定义输出文件名，不需要指定main文件的文件名，非常的好，非常的方便，注释也很详细，收藏并分享给需要的人。

CC      = gcc
CPP     = g++
RM      = rm -rf

## debug flag
DBG_ENABLE   = 1

## source file path
SRC_PATH   := .

## target exec file name
TARGET     := test

## get all source files
SRCS         += $(wildcard $(SRC_PATH)/*.c)

## all .o based on all .c
OBJS        := $(SRCS:.c=.o)


## need libs, add at here
LIBS := pthread

## used headers  file path
INCLUDE_PATH := .

## used include librarys file path
LIBRARY_PATH := /lib

## debug for debug info, when use gdb to debug
ifeq (1, ${DBG_ENABLE}) 
	CFLAGS += -D_DEBUG -O0 -g -DDEBUG=1
endif

## get all include path
CFLAGS  += $(foreach dir, $(INCLUDE_PATH), -I$(dir))

## get all library path
LDFLAGS += $(foreach lib, $(LIBRARY_PATH), -L$(lib))

## get all librarys
LDFLAGS += $(foreach lib, $(LIBS), -l$(lib))


all: clean build

build:
	$(CC) -c $(CFLAGS) $(SRCS)
	$(CC) $(CFLAGS) -o $(TARGET) $(OBJS) $(LDFLAGS)
	$(RM) $(OBJS)

clean:
	$(RM) $(OBJS) $(TARGET)

注意有一些空行的开头是tab键，但是csdn自动改成了4个空格。需要注意。

### Customising 
# 
# Adjust the following if necessary; EXECUTABLE is the target 
# executable"s filename, and LIBS is a list of libraries to link in 
# (e.g. alleg, stdcx, iostr, etc). You can override these on make"s 
# command line of course, if you prefer to do it that way. 
# 
EXECUTABLE := $(prog_name) 
LIBS := -lpthread #库文件   没有可不写
# Now alter any implicit rules" variables if you like, e.g.: 
# 
CFLAGS := -g -Wall -O
CXXFLAGS := $(CFLAGS) 
CC := arm-linux-gcc   #编译器
# The next bit checks to see whether rm is in your djgpp bin 
# directory; if not it uses del instead, but this can cause (harmless) 
# `File not found" error messages. If you are not using DOS at all, 
# set the variable to something which will unquestioningly remove 
# files. 
# 
ifneq ($(wildcard $(DJDIR)/bin/rm),) 
RM-F := rm -f 
else 
RM-F := del 
endif 
# You shouldn"t need to change anything below this point. 
# 
# ................... 
SOURCE := $(wildcard *.cpp) $(wildcard *.c) 
OBJS := $(patsubst %.cpp,%.o,$(patsubst %.c,%.o,$(SOURCE))) 
DEPS := $(patsubst %.o,%.d,$(OBJS)) 
MISSING_DEPS := $(filter-out $(wildcard $(DEPS)),$(DEPS)) 
MISSING_DEPS_SOURCES := $(wildcard $(patsubst %.d,%.cpp,$(MISSING_DEPS)) $(patsubst %.d,%.cpp,$(MISSING_DEPS))) 
CPPFLAGS += -MD 
.PHONY : everything deps objs clean veryclean rebuild 
everything : $(EXECUTABLE) 
deps : $(DEPS) 
objs : $(OBJS) 
clean :
	@$(RM-F) *.o 
	@$(RM-F) *.d

veryclean: clean
	@$(RM-F) $(EXECUTABLE)
	@$(RM-F) *.*~ *~ 
distclean: veryclean 
rebuild: veryclean everything 
ifneq ($(MISSING_DEPS),) 
$(MISSING_DEPS) :
	@$(RM-F) $(patsubst %.d,%.o,$@) 
endif 
-include $(DEPS)

$(EXECUTABLE) : $(OBJS)
	$(CC) -o $(EXECUTABLE) $(OBJS) $(addprefix ,$(LIBS))

这个也是我经常用的makefile，有汉语注释更容易理解。
