在托管 C++/CLR 中编译静态 C++ 库时LNK2028 LNK2029

Question

由于我几乎没有想法，并且谷歌结果现在已经达到了~10或更少的程度，我现在转向这里，希望看到答案或至少是引导我找到实际解决方案的线索。

我正在创建一个可以作为可执行、非静态库和静态库分发的项目。 我想在 WPF 项目 (C#( 中使用该库，这就是我创建一个简单的 CLR 包装器的原因。

直到最近引入基础库的更改之前，这一切都运行良好。 现在，我在库项目中对"main"类的所有调用中都收到链接错误(总共 5 个(：

能够通过添加另一个分离层(wrapper.cpp & wrapper.h(然后在 cpp 文件的顶部放置一个#pragma unmanaged来摆脱LNK2028问题。 现在只剩下LNK2019问题

Answer 1

对于那些将来可能会发现这个问题的用户，以下是对我的帮助：

1. 分离所有类
2. 将#pragma managed添加到实际类的非托管包装器中(删除了LNK2028(

3. 以下提交之一：

   • 将无效放置的 C 方法从通常不以任何方式涉及的external "C"移动到构建的静态库，但可能会干扰 CLR 构建过程，因为标头仍然存在
   • 更改构造函数的排列

希望这对你有帮助。
