Question

您好，我目前正在尝试在Visual Studio 2015中设置Direct X项目。

我已经下载了正确的SDK并将项目链接到正确的目录，这是我在uni上所教的内容。（整个项目只是简单地复制了提供的Word文档中的代码）

我发现这是导致错误的唯一代码行。

if (FAILED(InitialiseWindow(hInstance, nCmdShow)))
{
    DXTRACE_MSG("Failed to create Window");
    return 0;
}

如果我注释掉DXTRACE_MSG，那么程序就会正确符合。

确切的错误是LNK2019未解析的外部符号__vsnprintf在函数＆＃34中引用; long __stdcall StringVPrintfWorkerA（char *，unsigned int，unsigned int *，char const *，char *）＆＃34; （？StringVPrintfWorkerA @@ YGJPADIPAIPBD0 @ Z）教程01练习01 C：\ Users \ Tony \ Desktop \ AGP \ Tutorial 1练习01 \ dxerr.lib（dxerra.obj）。

总的来说，我只是需要帮助来理解错误，它为什么会发生以及我可以做些什么来纠正错误，这样我就可以继续按照我的工作需要继续前进。

非常感谢任何帮助。
