我正在尝试构建一个具有 Boost 和 OpenCV 依赖项的项目。其他具有类似依赖关系的项目似乎工作正常，但这会引发以下错误：

这里可能的问题是什么？

我已将宏轮的名称更改为其他名称，现在它已经过去了这些错误。但是现在，又出现了另一个错误：实际上这是一个 linux 实现。我正在尝试在 Windows 中运行它，因此我将 windows 中的 timeoftheday 实现添加到代码中。

看起来有些东西正在声明一个名为“round”的宏。

在您的错误中，请参阅以下行：

1>C:\boost_1_54_0\boost_1_54_0\boost/math/special_functions/round.hpp(20): warning C4002: too many actual parameters for macro 'round'

#define round在任何库依赖项和您自己的代码中进行文件范围的搜索。

根据它的定义，您可能有一些解决问题的选项：

  • 不要包含标题
  • 查看标头是否未定义round是否可以在构建设置中包含一些预定义的宏。
  • #undef包括提升之前的回合
  • #include预编译头文件中的头文件和#undef回合
