我从教科书中再次使用此PCNN代码 我在pcn2d.cc中的相关行中得到“无匹配函数调用”错误 使用变量F，L，U，T和Y.以下是类文件，代码文件和编译器日志：

答案 0 :(得分：2)
它谈到的不完全匹配对rimage::rimage(rimage&)的调用。这通常意味着您尝试从临时对象进行复制，该临时对象可以使用此复制构造函数如果它是rimage::rimage(const rimage&)。
为什么不呢？因为代码是15年，从之前有一个C ++标准？
答案 1 :(得分：0)
是 - 您的副本构造函数必须为rimage(const rimage& other) - 请注意其他const。
ms的编译器出于某种原因支持将其作为扩展名。
在const到位的情况下，将允许符合标准的编译器（通过标准）创建/使用临时rimage实例，除非有转换且您已声明构造函数{{ 1}}。
解决方案：您必须
1）提供一个复制构造函数，它使用const限定符作为其参数
2）或显式创建一个非const explicit实例并将其传递给副本。
更好/适用取决于实际实施，在某些情况下，还取决于启用复制的成本/副作用。
