如何解决'未解决的外部符号'

Question

我想运行项目Objectness，Main.cpp。我从网站下载的代码。我在大约5年后再次使用C ++。

我有错误'未解析的外部符号'。我阅读了相关问题“Unresolved external symbol in object files”。

所以我发现这些外部符号已在Objectness.cpp中定义。

确切的错误是

1>  Touching "x64\Debug\Objectness.unsuccessfulbuild".
1>ClCompile:
1>  All outputs are up-to-date.
1>ManifestResourceCompile:
1>  All outputs are up-to-date.

有谁能告诉我如何解决这个问题？提前谢谢！
