很久没有写C++程序了，很多东西都忘了，几天试了一下protobuf的，顺便写了Makefile：

根据./proto/目录下的addressbook.proto（ 内容请参考）生成.cc和.h文件，放到./cpp/proto/目录下

$ protoc -I=./proto/ --cpp_out=./cpp/proto/ ./proto/addressbook.proto

在 ./cpp/ 目录下

$ cd ./cpp

编写reader.cc 和 writer.cc（ 内容请参考 ）

编写Makefile文件，关于gcc编译过程和makefile中的特殊符号，请参考和

$ cat Makefile LIBS=-lprotobuf CC=gcc ARGS=-Wall -c all:reader writer reader:reader.o addressbook.pb.o         $(CC) $^ $(LIBS) -o $@ writer:writer.o addressbook.pb.o         $(CC) $^ $(LIBS) -o $@ reader.o:reader.cc proto/addressbook.pb.h         $(CC) $(ARGS) $*.cc -o $@ writer.o:writer.cc proto/addressbook.pb.h         $(CC) $(ARGS) $*.cc -o $@ addressbook.pb.o:proto/addressbook.pb.cc proto/addressbook.pb.h         $(CC) $(ARGS) proto/$*.cc -o $@ clean:         rm *.o -f         rm reader writer -f

生成reader和writer程序

$make

测试 writer和reader

$ ./writer address.txtEnter person ID number: 01Enter name: donalEnter email address (blank for none): donal0412@gmail.comEnter a phone number (or leave blank to finish): 88236017Is this a mobile, home, or work phone? workEnter a phone number (or leave blank to finish):

$ ./reader address.txt Person ID: 1  Name: donal  E-mail address: donal0412@gmail.com  Work phone #: 88236017
