在VS2012项目上编译Boost C++库

Compiling Boost C++ libraries on VS2012 project

本文关键字：Boost C++ 编译 VS2012 项目      更新时间：2023-10-16

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

这里可能出现的问题是什么？

我已将宏回合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，另一个错误出现了：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 time oftheday 在 windows 中的实现添加到代码中。

看起来有什么东西在声明一个名为"round"的宏。

在您的错误中，请参阅以下行：

1>C:boost_1_54_0boost_1_54_0boost/math/special_functions/round.hpp(20): warning C4002: too many actual parameters for macro 'round'

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

根据定义的内容，您可能有几个选项来解决问题：

  • 不要包含标头
  • 查看标头是否未定义round是否有一些预定义的宏可以包含在生成设置中。
  • #undef回合，然后包括增强
  • 在预编译的标头中#include标头并#undef轮
