【中文标题】MongoDB C++ 初始化导致 Qt 崩溃【英文标题】：Qt break down by MongoDB C++ initialization 【发布时间】：2018-05-03 09:13:28 【问题描述】：我刚开始在 Qt 中使用 MongoDB c++。
我已经按照MongoDB教程(https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/tutorial/)安装了Boost，MongoDB c驱动，MongoDB c++驱动，并在VS2017上成功测试了DB的连接。
但是，当我想在 Qt 上应用相同的代码时，出现了很多问题。
整体设定：
-
Win10
Qt Creator v4.6.0 与
Qt v5.10.1 MSVC2017 64位
Microsoft Visual C++ 编译器 15.0
调试器 CDB x64
MongoDB v3.6.3
将 1.66.0 提升为 lib64-msvc-14.1
Mongo c驱动v1.9.3
Mongo cxx 驱动 r3.2.0
程序在初始化实例的时候就崩溃了，如下图： Break Down
只使用时程序也崩溃了
$mongocxx::instance inst()
编译为 using 时产生 C4930 警告
$mongocxx::instance inst()
我想我的问题有两个潜在原因 链接错误 错误版本的 boost/mongocxx 驱动程序 以下是 .pro 文件中的定义

链接驱动有错误吗？
或者我使用的驱动版本不正确（但是使用VS2017正常）
有人遇到同样的问题吗？ TKS
【问题讨论】：
【参考方案1】：我在mongodb邮件列表上回复了你，但是你在这里做的很多事情都是不正确的。您不应该同时链接库的静态和动态版本。您不应该同时链接 boost 库的零售版本和调试版本等。您应该确保链接一致版本的 boost、QT 和 mongocxx/bsoncxx/libmongoc/libbson 库 w.r.t。调试/发布、静态/动态等。
我建议从首要原则开始，并根据需要逐步建立。从 mongocxx 项目中获取一个示例，并设置一个项目，该项目成功地针对您构建的驱动程序构建它。然后添加 QT 支持。
