The procedure entry point could not be located in the dynamic link library Core.dll
提问by stijn
I am converting my project to use DLLs and am trying to break apart my Singletonclass to avoid using templates.
我正在将我的项目转换为使用 DLL，并试图拆分我的Singleton类以避免使用模板。
My class, LudoMemory, originally inherited from Singleton. I am trying to give it the functions to destroy and create itself now and have my main engine not rely on the Singleton.
我的班级，LudoMemory最初继承自Singleton. 我正在尝试赋予它现在销毁和创建自身的功能，并使我的主引擎不依赖于Singleton.
I have written a simple destroy method like such:
我写了一个简单的销毁方法，如下所示：
LudoMemory *memory_Singleton = NULL;
void LudoMemory::Destroy()
{
LUDO_SAFE_DELETE(m_Singleton)
}
and upon running the program (no compiler errors) I recieve this error:
在运行程序（没有编译器错误）时，我收到了这个错误：
The procedure entry point ?Destroy@LudoMemory@@SAXXZ could not be located in the dynamic link library LudoCore.dll
过程入口点 ?Destroy@LudoMemory@@SAXXZ 无法在动态链接库 LudoCore.dll 中定位
LudoCoreis the project that LudoMemorybelongs to. Why is this happening? How can I solve it?
LudoCore是LudoMemory属于的项目。为什么会这样？我该如何解决？

you don't have multiple versions of ludocore.dll on your system, do you? Procedure entry points errors usually mean: you compiled your project against ludocore.lib version x, and when running the program, it uses ludocore.dll version y, and version y does not define LudoMemory::Destroy().
你的系统上没有多个版本的 ludocore.dll ，是吗？过程入口点错误通常意味着：您针对 ludocore.lib 版本 x 编译您的项目，并且在运行程序时，它使用 ludocore.dll 版本 y，而版本 y 没有定义 LudoMemory::Destroy()。

Jacob's answer about multiple DLL versions seems likely.
雅各布关于多个 DLL 版本的回答似乎很可能。
Also, with some build systems, you must explicitly list which functions will be exported in a DLL.
此外，对于某些构建系统，您必须明确列出将在 DLL 中导出的函数。
Research your build environment, and see if you must provide a list of methods to be exported as an entry-point.
研究您的构建环境，看看您是否必须提供要作为入口点导出的方法列表。

In Visual Studio build environment, also you could try by disabling the References in Linker Optimization Settings [ No(/OPT:NOREF)]
在 Visual Studio 构建环境中，您也可以尝试禁用链接器优化设置中的引用 [ No(/OPT:NOREF)]
