Makefile

简单示例:

#CFLAGS=-Wall -ggdb
CFLAGS=-ggdb
LIBS=-lmosquittopp -lcurl -llog4cxx -lpthread

.PHONY: all clean

all : server

server : server.o mqtt_server.o utils.o CHttpClient.o
        ${CXX} $^ -o $@ ${LIBS}

server.o : server.cpp
        ${CXX} -c $^ -o $@ ${CFLAGS}

mqtt_server.o : mqtt_server.cpp
        ${CXX} -c $^ -o $@ ${CFLAGS}

utils.o : utils.cpp
        ${CXX} -c $^ -o $@ ${CFLAGS}

CHttpClient.o : CHttpClient.cpp
        ${CXX} -c $^ -o $@ ${CFLAGS}

clean : 
        -rm -f *.o server

运行可执行文件出错
./server: error while loading shared libraries
