我正在尝试构建一个具有Boost和OpenCV依赖项的项目。其他项目具有类似的依赖关系似乎工作正常，但这会引发以下错误：在VS2012项目上编译Boost C++库

这里有什么可能的问题？
我已经改变了宏的名称舍入其他东西，现在它过去这些错误。但是现在又出现了另一个错误：实际上这是一个Linux实现。我试图在Windows中运行它，因此我在windows中添加了timeoftheday实现代码。

确保您已包括升压和_Additional包括Directories_你必须提高，也不能肯定，如果你的路径需要一些定义 –
是增强包含在路径和Addn中。含。迪尔。其他项目正在使用此配置运行。只有这个项目出现这个错误。 –
那么主要定义在哪里？你是否在demo.cpp，eval_ffd.cpp，train_ffd.cpp，train_headpose.cpp包含的头文件中实现它？其他一些功能也一样。如果需要，可以将函数的protoctype放在标题中，然后在cpp文件中执行 – Pete
