Google Protobuf¶

1. 编译protobuf
   

   cd protobuf/
   unzip protobufsource-v21.11.zip 
   cd protobufsource-v21.11
   ./configure --prefix=/usr/local/protobuf
   

1. 设置库环境
   

   export LD_LIBRARY_PATH=/usr/local/protobuf:$LD_LIBRARY_PATH
   

1. 查看版本
   

   /usr/local/protobuf/bin/protoc --version
   

1. python示例
   

   /usr/local/protobuf/bin/protoc -h
   cd protobuf/
   /usr/local/protobuf/bin/protoc --python_out=. addressbook.proto
   python test_protobuf.py
   

1. c++示例
   

   /usr/local/protobuf/bin/protoc --cpp_out=. addressbook.proto
   g++ test_protobuf.cpp addressbook.pb.cc -o test_protobuf -lprotobuf -I/usr/local/protobuf/include -L/usr/local/protobuf/lib
   ./test_protobuf 
   
   /usr/local/protobuf/bin/protoc --cpp_out=. person.proto 
   g++ person.cpp person.pb.cc -o test -lprotobuf -I/usr/local/protobuf/include -L/usr/local/protobuf/lib
   ./test
   
   /usr/local/protobuf/bin/protoc --cpp_out=. mec2rsu.proto
   g++ test.cpp mec2rsu.pb.cc -o test -lprotobuf -I/usr/local/protobuf/include -L/usr/local/protobuf/lib
