왜 컴파일되지 않습니까?기능, bind1st 및 mem_fun
#include <functional>
#include <boost/function.hpp>
class A {
A() {
typedef boost::function<void()> FunctionCall;
FunctionCall f = std::bind1st(std::mem_fun(&A::process), this);
}
void process() {}
};

야호를 사용하는 것이 좋습니다. 고맙습니다. –
boost :: bind (& (decltype (* this) :: process), this) 할 수 있습니까? 매크로에 넣으 려합니다. –
@Neil 가장 최근의 초안은'decltype'을 중첩 된 이름 지정자 ('::'앞에있는 것)로 사용할 수있게 만들었습니다. 또한 유형에서 참조를 제거해야합니다. 현재 GCC 버전이 아직 지원하지 않을 수도 있습니다. 이 경우, 대신에 & remove_reference :: type :: process'를 호출하여 작업 해보십시오. –
