解决GoogleProtocolBuffers 枚举的问题
发表于2018-06-05
有如下的proto文件：
syntax = "proto3"; enum GameType ｛ Invalid = 0; RPG = 1; ｝ enum ComputerType ｛ Invalid = 0; PC = 1; ｝在编译的时候就会报错，因为要兼容C++，会有如下的报错：
test.proto:11:9: "Invalid" is already defined.
test.proto:11:9: Note that enum values use C++ scoping rules, meaning that enum values are siblings of their type, not children of it. Therefore, "Invalid" must be unique within the global scope, not just within "ComputerType".
test.proto:11:9: Note that enum values use C++ scoping rules, meaning that enum values are siblings of their type, not children of it. Therefore, "Invalid" must be unique within the global scope, not just within "ComputerType".
解决方法如下：
syntax = "proto3"; message GameType ｛ enum Enum ｛ Invalid = 0; RPG = 1; ｝ ｝ message ComputerType ｛ enum Enum ｛ Invalid = 0; PC = 1; ｝ ｝但是呢，具体在运行的时候会有什么样的问题，目前我还没有遭遇，这只是提供了一个解决编译报错的方法。
还请各位自行斟酌！
