当我使用 boost 1.52.1 和 gcc-4.7.1 编译我的代码时,出现以下错误。这似乎是 boost 和 c++ 库之间的冲突。有人知道如何解决这个问题吗?
非常感谢您的回复。

错误出现在代码 boost\math\policy\error_handling.hpp 中。但我不确定程序何时引用这些函数。这个错误是怎么发生的?
template <class R, class T, class Policy>
inline bool check_overflow(std::complex<T> val, R* result, const
char* function, const Policy& pol)
{
typedef typename R::value_type r_type;
r_type re, im;
bool r = check_overflow<r_type>(val.real(), &re, function, pol) || check_overflow<r_type>(val.imag(), &im, function, pol);
*result = R(re, im);
return r;
}
template <class R, class T, class Policy>
inline bool check_underflow(std::complex<T> val, R* result, const char* function, const Policy& pol)

bool r = check_underflow<r_type>(val.real(), &re, function, pol) || check_underflow<r_type>(val.imag(), &im, function, pol);
*result = R(re, im);
return r;
}
