我试图建立mongocxx驱动程序库C++定义指令失败，代码看起来OK

并且得到错误以上。
这里是有问题的代码（一行少添加＃秒）：
46 #ifdef __cplusplus
47 # define BSON_BEGIN_DECLS extern "C" {
48 # define BSON_END_DECLS }
49 #else
50 # define BSON_BEGIN_DECLS
51 # define BSON_END_DECLS
52 #endif
该代码看起来不错给我。有人能指出我错过了什么吗？在包含中上游会有问题吗？如何找到它？
干杯
我认为你只能定义常量或函数宏，而不是块的一部分。 –
你可以显示代码在哪里抱怨宏扩展？ – NathanOliver
什么版本的C++ 11驱动程序？什么版本的C驱动程序？什么编译器？什么平台？ – acm
