## 问题 ##

### 1. Unresolved external symbol ###

当把 `imp` 源文件与 `api` 源文件都作为DLL这一个目标的源码来编译时，在`imp`相关源码的链接时，出现如下链接错误：

```bash
error LNK2001: 无法解析的外部符号 "public: static struct QMetaObject const test::gl_painter::GLCloudWidget2D::staticMetaObject" (?staticMetaObject@GLCloudWidget2D@gl_painter@test@@2UQMetaObject@@B)
```

这个问题，在`test`使用__declspec(dllexport)导入该`DLL`时，也会出现该链接错误：[qt forum --Unresolved symbol in user DLL "public: static struct QMetaObject"](https://forum.qt.io/topic/159421/unresolved-symbol-in-user-dll-public-static-struct-qmetaobject).
