这是参考代码

我正在使用C ++驱动程序测试mongo的一些调用
除我添加此行外,它均有效
obj.appendBinData( "binTest",sizeof(test), BinDataGeneral, test);
这是错误消息
ninexample.cpp: In function ‘int main(int, const char**)’:
ninexample.cpp:73:48: error: ‘BinDataGeneral’ was not declared in this scope
obj.appendBinData( "binTest",sizeof(test), BinDataGeneral, test);
^
ninexample.cpp:73:48: note: suggested alternative:
In file included from /usr/include/mongo/db/jsobj.h:34:0,
from /usr/include/mongo/client/dbclientinterface.h:25,
from /usr/include/mongo/client/connpool.h:23,
from /usr/include/mongo/client/dbclient.h:32,
from ninexample.cpp:22:
/usr/include/mongo/bson/bsontypes.h:102:9: note: ‘BinDataGeneral’
BinDataGeneral=0,
^
我是C ++的新手,所以我不确定为什么这里会出现错误,因为似乎在h文件中看到类型BinDataGeneral。
谁能为我澄清一下?
谢谢!
最佳答案
编译器正在寻找BinDataGeneral
,但无法解析该符号。
尝试mongo::BinDataGeneral
。
关于c++ - 功能参数“未在此范围内声明”。参数在h文件中可见,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/19439128/
