相关的编译错误提振 [英] compiling errors related boost

问题描述

当我使用升压1.52.1和gcc-4.7.1编译我的code，出现以下错误。看来这是升压和C ++库之间的冲突。
可能有些人知道如何解决这个问题呢？

您的回复非常感谢。

出现在code提振\\数学\\政策\\ error_handling.hpp错误。但我不知道当程序引用这些功能。这是如何发生的错误？

解决方案

鉴于这种两个功能，这嘈杂的错误消息，我可以说，类型作为参数R不定义 VALUE_TYPE 。正因为如此，键入 R_TYPE 和变量即时消息和重新没有定义。作为结果，你得到错误：'聊天室'在此范围未声明错误

使用仅供code，我可以看到，R型有这样的要求：

• 它必须定义类型 VALUE_TYPE


• 它必须具有构造 R（VALUE_TYPE真实的，VALUE_TYPE想象）

这一切都意味着您使用不正确地使用internaly check_underflow / check_overflow功能，不兼容的模板参数一些boost库，我猜。

When I use boost 1.52.1 and gcc-4.7.1 to compile my code, the following errors appear. It seems this is conflict between boost and c++ library. Could some know how to resolve this problem?

Many thanks for your reply.

 in this scope

The error appears in the code boost\math\policy\error_handling.hpp. But I am not sure when the program cite these functions. How does this error happen?

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)
{
     typedef typename R::value_type r_type;
     r_type re, im;
     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;
}

解决方案

Given this two functions and this noisy error message I can say that type that was used as parameter R doesn't defines value_type. Because of that, type r_type and variables im and re is not defined. As result you get error: 'im' was not declared in this scope error.

Using only provided code I can saw that type R has this requirements:

• It must define type value_type
• It must have constructor R(value_type real, value_type imagine)

All this means that you use some boost library that uses internaly check_underflow/check_overflow functions incorrectly, with incompatible template argument, I guess.
