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
附:源代码
