我一直在尝试使用 DirectX 11 一段时间，首先我有 Windows 7 的 Visual Studio 2010，当它没有创建 Direct3D 设备时遇到了 SDK 错误。所以我卸载了 SDK 并安装了 Visual Studio 2012，并使用了一套全新的代码来尝试创建窗口。

这是我现在尝试构建项目时遇到的错误：

error LNK2019: unresolved external symbol _D3D11CreateDeviceAndSwapChain@48 referenced in function "void __cdecl InitD3D(struct HWND__ *)" (?InitD3D@@YAXPAUHWND__@@@Z) C:\Users\thatguy\Documents\game dev\tutorial work\directx 11 tutorial\directx 11 tutorial\main.obj  directx 11 tutorial

这是我要编译的代码：

// this is the function that cleans up Direct3D and COM
void CleanD3D(void)
{
    // close and release all existing COM objects
    swapchain->Release();
    dev->Release();
    devcon->Release();
}

我添加了 DirectX 包含目录和 lib x64 和 x86 目录，但它仍然失败。

您需要在属性 -> 链接器 -> 输入 -> 附加依赖项中添加 D3D11.lib。

你试过吗？

不要再使用 d3dx11.h。在 initd3d 函数之后调用 d3dclean。
