c++ - 未解析的外部符号 _D3D10CreateDeviceAndSwapChain@32 在函数“public : bool 中引用

Question

在创建我的交换链时遇到问题。我收到以下错误。

DX3dApp.obj : error LNK2019: unresolved external symbol _D3D10CreateDeviceAndSwapChain@32 referenced in function "public: bool __thiscall DX3dApp::InitDirect3D(void)" (?InitDirect3D@DX3dApp@@QAE_NXZ)

下面是我到目前为止完成的代码。

#include "DX3dApp.h"

        Render();

您没有链接到 D3D 库 (D3D10.lib)。

将该库添加到您的链接器选项(项目属性 -> 链接器 -> 输入 -> 附加依赖项)。您还需要确保库位置位于“其他库目录”路径中。
