Question

我正在尝试在Windows 10 64bit上使用MinGW（G ++ 6.3.0）编译Mongo C ++ 11驱动程序。从GCC 6发行说明;

默认模式已更改为-std = gnu ++ 14。

我的理解是默认情况下也支持C ++ 11。为什么我会收到有关互斥和线程的错误消息？

mongocxx目前为only supports MSVC on Windows，因此可能无法使用MinGW进行构建。话虽如此，如果您还没有，我建议您在CMAKE_CXX_FLAGS中传递-std=c++11以查看是否有效。

C ++编译错误，std中的互斥锁没有在MinGW中命名一个类型（GCC 6.3.0）
