我有类eventEngine和网关，如下所示：
class eventEngine
{
public:
eventEngine();
std::thread threa;
std::thread timer;
};
class Gateway
{
protected:
eventEngine ee;
std::string gatewayName;
};
网关的构造函数：
Gateway::Gateway(eventEngine ee, std::string gatewayName)
{
this->ee.threa = std::move(ee.threa);
this->ee.timer = std::move(ee.timer);
this->gatewayName = gatewayName;
}
和main1.cpp：
int main()
{
eventEngine e;
std::string names = "abc";
Gateway g(e,names);
return 0;
}
当我尝试在main1.cpp中进行编译时，出现错误：
main1.cpp:12:21: error: use of deleted function 'eventEngine::eventEngine(const eventEngine&)'
Gateway g(e,names);
^
In file included from Gateway.h:11:0,
from main1.cpp:2:
eventEngine.h:25:7: note: 'eventEngine::eventEngine(const eventEngine&)' is implicitly deleted because the default definition would be ill-formed:
class eventEngine
^
eventEngine.h:25:7: error: use of deleted function 'std::thread::thread(const std::thread&)'
In file included from Gateway.h:8:0,
from main1.cpp:2:
/usr/lib/gcc/x86_64-pc-cygwin/5.3.0/include/c++/thread:126:5: note: declared here
thread(const thread&) = delete;
^
In file included from Gateway.h:11:0,
from main1.cpp:2:
eventEngine.h:25:7: error: use of deleted function 'std::thread::thread(const std::thread&)'
class eventEngine
我已经搜索了类似的问题，似乎std :: thread有问题，线程是非复制类，我已更改为std :: move，如本-> ee.threa = std :: move（ee.threa ）; this-> ee.timer = std :: move（ee.timer）; 但它仍然给我错误，这是什么问题？
要使此工作有效，您应该更改代码：
Gateway::Gateway(eventEngine&& ee, std::string&& gatewayName)
{
this->ee = std::move(ee);
this->gatewayName = std::move(gatewayName);
}
和
Gateway g(std::move(e), std::move(names));
或简单地
Gateway g(eventEngine{}, "abc");
但是最好的方法是以标准形式编写：
Gateway::Gateway(eventEngine&& ee, std::string&& gatewayName) : ee{std::move(ee)}, gatewayName{std::move(gatewayName)} {}
您的代码无效，因为您尝试使用copy-ctor初始化函数参数，由于复制了std::thread的和分别eventEngine的copy-ctors，该参数被删除了。您应该使用移动螺丝代替它们。
