我不知道代码有什么问题，错误是什么意思？有人能帮忙吗。

const CLM&other

是一个r值参考。这些是C++ 11标准中对C++的新补充。将

-std=c++11

（或

-std=c++0x

如果您使用的是较旧的编译器，请查看文档）添加到编译器调用中。

const CLM&&other

是一个r值引用。这些是C++ 11标准中对C++的新补充。将

-std=c++11

（或

-std=c++0x

如果您使用的是较旧的编译器，请查看文档）添加到您的编译器调用中。

您使用的是

，它是一个。因此，您应该告诉编译器您正在使用

c++11

。在GCC中，您通过传递

-std=c++11

来实现这一点，您使用的是

，这是一个，它仅在

c++11

中有意义。因此，您应该告诉编译器您正在使用

c++11

。在GCC中，您通过传递

-std=c++11

来实现这一点，您的编译器似乎不支持c++11.1）您是在启用c++11支持的情况下编译的吗？2）常量值引用是毫无意义的。不相关的：我必须承认，CLM的传统TLA让我笑了。如果你的“移动构造函数”只是要复制，你也可以省略它，让复制构造函数被选中，如果你的复制语义是复制每个成员，那么就同时省略这两个并使用默认生成的版本。你的编译器似乎不支持C++11.1）你是在启用C++11支持的情况下编译的吗？2）常量值引用是毫无意义的。不相关的：我必须承认，CLM的传统TLA让我笑了。如果你的“移动构造函数”只是要复制，您也可以省略它，让复制构造函数被选择，如果复制语义是复制每个成员，那么就同时省略这两个成员，并使用默认生成的版本Accepted as answer，因为它首先被回答@Ivaylo Strandjev也感谢您的回答和您的参考链接。作为答案接受，因为它是第一个回答@Ivaylo Strandjev也感谢您的回答和参考链接。
