我有一个名为GMC的dll，其中包括另一个名为nlopt（https://nlopt.readthedocs.io/en/latest/NLopt_on_Windows/）的dll。我可以创建一个控制台，将GMC添加到项目中，然后运行该程序而不会出现任何问题。但是，当我尝试将GMC添加到特定项目时，采取与将其添加到我制作的控制台相同的所有步骤（包括头文件，添加对dll的引用，其他包含目录），我得到了这些{{3} }
在VS2017中工作时，我没有这个问题。由于这个问题不重要，我不得不改用VS2013。最初，我认为这些链接错误是由于我正在使用VS2013中从VS2017创建的DLL引起的。但是，在VS2013中重新创建GMC和nlopt并将它们重新添加到我的项目中之后，仍然存在链接错误。
我还仔细研究了该项目的所有项目属性，并比较了它们与正在运行且没有发现差异的项目的链接错误（所有运行时库都是多线程调试DLL（/ MDd） ）。
错误：
