几个Mikefile文件模板

编译动态链接库：

# Project:
# Makefile created by [e-mail]

CPP = g++

#need to assign IKSEMEL_HOME to your own path
IKSEMEL_HOME = /data/soft/iksemel-1.3

OBJ = config.o msgheader.o msgbody.o msgmgr.o locker.o
LINKOBJ = $(OBJ)
LIBFLAGS = -liksemel
LIBS = -L. -L$(IKSEMEL_HOME)/lib
INCS = -I.
CXXINCS = -I. -I$(IKSEMEL_HOME)/include
CXXFLAGS = $(CXXINCS) -g -fPIC -Wall

RM = rm -f

TAG_SO = libmsg.so
TAG_A = libmsg.a


all : $(TAG_SO)
    cp -rf $(TAG_SO) ./lib

$(TAG_SO) : $(OBJ)
    $(CPP) -s -shared $(LIBS) $(LIBFLAGS) $^ -o $@

msgheader.o: msgheader.cpp
    $(CPP) -c $(CXXFLAGS) $< -o $@

config.o: config.cpp
    $(CPP) -c $(CXXFLAGS) $< -o $@

msgbody.o: msgbody.cpp
    $(CPP) -c $(CXXFLAGS) $< -o $@

msgmgr.o: msgmgr.cpp
    $(CPP) -c $(CXXFLAGS) $< -o $@

locker.o: locker.cpp
    $(CPP) -c $(CXXFLAGS) $< -o $@



.PHONY : clean
clean:
    ${RM} $(OBJ) *.out *.o *.so.* $(TAG_SO)



递归调用子目录下的makefile文件：


SUBDIRS = ./msg_mgr ./lock_class ./msg_mgr_testcase ./socket_class

all:
    for dir in $(SUBDIRS); do \
        $(MAKE) -C $$dir; \
    done

clean:
    for dir in $(SUBDIRS); do \
        $(MAKE) -C $$dir clean; \
    done


值得注意的地方：

$@ 目标文件,$^    所有的依赖文件,$< 第一个依赖文件.
