我在编译时总是收到此错误,但是我不知道为什么。我看过this个帖子和this一个帖子,但它们似乎是不同的问题。
相关代码结构为:
// main.cpp
#include "MyClass.h"
int main() {
MyClass newClass = MyClass();
}
// MyClass.h
#include <string>
#include <sstream>
#include <vector>
using namespace std;
class Node;
class MyClass {
private:
vector<Node*> nodes;
int number;
stringstream fileInfo;
public:
MyClass();
~MyClass();
};
// MyClass.cpp
#include "MyClass.h"
MyClass::MyClass() {
number = 1;
}
MyClass::~MyClass() {}
编译时出现的错误是:
main.cpp: In function 'int main()':
main.cpp:4:29: error: use of deleted function 'MyClass(const MyClass&)'
MyClass new Class = MyClass();
^
In file included from main.cpp:1:0:
MyClass.h:7:7: note: 'MyClass::MyClass(const MyClass&)' is implicitly deleted because the definition would be ill-formed:
class MyClass {
^
MyClass.h:7:7: error: use of deleted function 'std::__cxx11::basic_stringstream<_CharT, _Traits, _Alloc>::basic_stringstream(const std::__cxx11:basic_stringstream<_CharT, _Traits, _Alloc>&) [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>]'
In file included from MyClass.h:2:0,
from main.cpp:1:
/usr/included/c++/5/sstream:721:7: note: declared here
basic_stringstream(const basic_stringstream&) = delete;
^
我尝试初始化构造函数中的所有类成员,但是并没有改变错误。除此之外,我想不出什么问题。
答案 0 :(得分:2)
问题在于您的类不可复制,因为它包含一个{u'rowData': [
{u'values': [{}, {u'note': u'B1 notes'}, {}, {}, {u'note': u'E1 notes'}]},
{},
{},
{u'values': [{}, {}, {}, {u'note': u'D4 notes'}]},
{},
{},
{u'values': [{}, {u'note': u'B7 notes'}]}
]
}
(它本身是不可复制的)。这导致其副本构造函数被删除,这是编译器试图告诉您的。要解决此问题,只需不要在''
函数中使用复制初始化语法。
std::stringstream
