将 C/C++ 源文件作为插件包含在 IL2CPP [关闭]

[英]Include C/C++ source files as plugins in IL2CPP [closed]

问题描述

我一直在尝试用 C 语言编写简单的函数，并使用 IL2CPP 将它们直接包含在我的插件目录中，而无需构建 DLL，因为我发现它更直接，而且 P/Invoke 的成本更低，而且可能不需要每次都重新启动 Unity是时候我做出改变了。

但是，当我将 IL2CPP 脚本后端与独立目标作为目标时，我总是在播放模式下的编辑器中收到此错误： EntryPointNotFoundException而当我构建时，我得到/il2cpp.exe did not run properly!

我有 VS2019 w/ C++ 工作负载和 Windows 10 SDK。

任何人都知道如何在 Unity 中使用本机源文件和 IL2CPP？

示例代码：

#include <math.h>
#define EXPORT __declspec(dllexport)

/* Power function*/
EXPORT int power1(int n, int p)
{
    int r = pow(n, p);
    return r;
}

C＃

[DllImport("__Internal", EntryPoint ="power1")] static extern int power1(int n, int p);

编辑：我得到的错误：

你没有发布 Unity 给你的完整错误，所以我猜你遇到了什么错误......在任何一种情况下，这都不起作用，因为：

  1. C# 默认使用__stdcall调用约定，而 C/C++ 使用__cdecl 。 因此，链接器将无法在链接时找到您的函数，并且会出错。 您需要在 P/Invoke 声明或本机定义中修复它。

  2. 如果您的源文件是一个.cpp 文件，您需要将您的函数标记为extern "C" ，这样编译器就不会破坏它的名称，因此它可以被P/调用。

至于编辑器中的 EntryPointNotFoundException：Unity 编辑器不支持此功能。 它仅适用于使用 IL2CPP 脚本后端制作的构建。
