c++定义指令失败，代码看起来正常

Question

我正在尝试构建mongo-cxx-驱动程序库。

mmuratet@fisher:~/mongo-cxx-driver/build$ cmake --prefix=/usr/local ..
-- No build type selected, default is Release

/usr/local/include/libmongoc-1.0/mongoc-stream-tls-private.h:61:1: note: in expansion of macro ‘BSON_END_DECLS’
 BSON_END_DECLS

^ make2：* 错误1 make1：* src/mongocxx/CMakeFiles/mongocxx.dir/all Error 2作出：*所有错误2

得到上面的错误。

下面是违规代码(第#行添加了更少的代码)：

 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

这段代码在我看来没问题。有人能指出我错过了什么吗？其中是否存在上游问题？怎么才能找到它呢？

干杯

Answer 1

看来您使用的是主分支中的libmongoc，它似乎有一个错误，其中该BSON_END_DECLS与上面的BEGIN_DECLS不成对(它在以前的提交中被意外地删除了)

我在：https://jira.mongodb.org/browse/CDRIVER-1162上输入了一个bug

1.3.4标记是一个实际的稳定版本，似乎没有相同的问题。
