c++ - 如何解决这个错误 ":(.text+0x4d): undefined reference to ` _imp___ZN10Management11OpenEm'"

Question

我需要在 C 程序中调用 C++ 程序中的一些方法。

但我只有一个共享库 (.dll) 来使用这些方法。

要做到这一点，首先要在 C 中创建一个包装器，以调用要在 C 程序中使用的 dll 中的方法。我注意并确保使用 extern "C" 声明函数以避免名称混淆。

但是当编译时我有一组错误(显示在下方)当链接墙 .o 时:

有人知道我做错了什么吗？

您是否在包装方法源文件中包含了 extern "C"函数声明头文件？否则会出现这个错误
