我正在尝试在 Visual Studio C++ Express 2010 中使用 Boost 构建解决方案并收到以下错误：

由于您没有显示任何代码，我们只能猜测。我的猜测是你#define的一些宏会弄乱Boost.Math代码。也许像#define M ......

更新：事实证明我的猜测是正确的。看看MedLDAc/MEDsLDAc/cokus.h file：

#define M              (397)                 // a period parameter

直接的解决方法是将#include <boost/math/special_functions/gamma.hpp>line移入MedLDA.cpp成为第一个包含在 之后StdAfx.h的，以便上述宏不会影响在 中声明的模板gamma.hpp。

PS 定义一个字母的宏是一个非常非常糟糕的主意。
