c++ - 是什么导致我的 "‘FatalError’ in namespace ‘Foam’ does not name a type”错误？

Question

我有一个奇怪的错误，一段时间以来我都没有设法解决。我想通过与英特尔 OpenVINO 的推理引擎一起使用来扩展一个 C++ 软件包。因此，我必须动态链接一些库并将一些 header 包含到现有代码中。之前，它编译没有任何错误。然后我包含找到的第一个头文件 (#include "inference_engine.hpp")，但我收到此错误消息

除了包含额外的标题外，我没有做任何更改，而且错误消息非常奇怪。一位同事提到，所涉及的两个程序(OpenFOAM 和 OpenVINO)之间可能存在一些“冲突”。有人可以提示我可能是什么问题吗？

谢谢!

编辑:也许我应该指出这两个部分:

/opt/OpenFOAM/OpenFOAM-4.1/src/OpenFOAM/lnInclude/error.H:316:13: error: ‘FatalError’ in namespace ‘Foam’ does not name a type
     ::Foam::FatalError((functionName), __FILE__, __LINE__)

         << "Not implemented" << ::Foam::abort(FatalError);

Answer 1

原因隐藏在错误转储的一半附近:

#define NotImplemented notImplemented(FUNCTION_NAME)

OpenFOAM 将其用作宏以在未实现的方法中引发错误，而 OpenVINO 恰好定义了一个具有相同名称的类。 C++ 命名空间仅在宏扩展后解析，因此这对您没有帮助。

您的选项，按偏好大致排序:

1. 首先包括 OpenVINO header ，然后是 OpenFOAM header 。这确实意味着如果您还想抛出或捕获这些异常，则必须 #undef NotImplemented。
2. 首先包含 OpenFOAM header ，然后是 #undef NotImplemented，然后包含 OpenVINO header 。这意味着您不能将 OpenFOAM 宏用于您自己的目的(尽管您可能不需要)。
3. 如果没有其他标题使用它，请从 OpenFOAM 标题中删除宏。
