protobuf简单序列化反序列化示例

protoc命令格式　

protoc    -I=SRC -cpp_out = DRC　SRC\*.proto　

SRC：源路径；

DRC:目的路径；

 

当出现下面无法打开文件错误时，应在工程属性目录下的包含目录文件中添加工程所在路径　D:\!exercise\c++\protob1\protob1\

错误 1 error C1083: 无法打开包括文件:“google/protobuf/stubs/common.h”: No such file or directory d:\!exercise\c++\protob1\protob1\google\protobuf\generated_message_util.h 43 1 protob1

 

当现现下面无法打开库文件时，应用工程属性目录下的库目录添加LIB文件所在路径：D:\!software\!develop\protobuf-2.5.0\protobuf-2.5.0\vsprojects\Debug

错误 3 error LNK1104: 无法打开文件“libprotoc.lib” D:\!exercise\c++\protob1\protob1\LINK protob1
