“呼叫没有匹配的功能”HAS我BAFFLED

我回来了这个PCNN代码从一本教科书。
我在变量F，L，U，T和Y中得到了关联
的行中pcn2d.cc中的“无匹配函数调用”错误。以下是类文件，代码文件和编译器日志：“呼叫没有匹配的功能”HAS我BAFFLED

由于这是C++文件，文件扩展名不应该是'.cc'或'.cpp'吗？ – Asha 2011-03-18 06:15:17

您能删除所有成员函数的实现并只保留一个有错误的实现吗？这样很容易理解和解决。 – balki 2011-03-18 06:22:49

采取的两点。这是我正在故意编写的文本书中的代码。我增加了超过必要的内容，以确保没有任何关键的东西被遗漏。我在论坛的帮助下解决了问题，我很高兴。 – databoy 2011-03-19 00:51:49

它谈论不rimage::rimage(rimage&)通话完全匹配。这通常意味着您正试图从临时对象复制，如果已使用此复制构造函数，则该对象可能是rimage::rimage(const rimage&)。

为什么不是？因为代码是15年前的，从此之前有一个C++标准？

再次感谢你们。这解决了问题，并且我成功编译了项目 – databoy 2011-03-19 00:43:37

yup - 您的拷贝构造函数必须是rimage(const rimage& other) - 请注意额外的const。

由于某种原因，ms的编译器支持将其作为扩展。

与地方const，符合标准的编译器（标准）被允许创建/使用临时rimage情况下，除非有一个转换，并声明该构造explicit。

解决方案：你将不得不

1）提供使用const修饰词并为它的参数

2）或明确创建一个非const rimage实例和传递的副本拷贝构造函数。

哪个更好/适用取决于实际的实施方式，以及在某些情况下，启用复印的成本/副作用。

复制构造函数需要一个const是正确的，但这不是编译器扩展。该规范显式允许您编写一个通过非const引用接受其参数的副本构造函数。 – templatetypedef 2011-03-18 06:51:42

谢谢，这解决了这个问题。我喜欢这个论坛！你们在正确答案的基础上是正确的。 – databoy 2011-03-19 00:46:10
