boost :: bindを使用しようとしています。次のコードセグメントで間違っていますか?私のコンパイラでエラー:オーバーロードされた 'bind(int(Class、*)(int、int)、Class *、int、int)'の呼び出しがあいまいです
#include <iostream>
#include <boost/bind.hpp>
using std::cout;
using std::endl;
class Class {
public:
int add(int x, int y) {
cout << "x+y=" <<x+y<<endl;
return x+y;
}
};
int main()
{
cout << "boost::thread: " << endl;
Class cls;
boost::bind<int>(&Class::add, &cls, 1, 2);
return 0;
}
G ++ - 4.7、それは言う:
main.cpp: In function ‘int main()’:
main.cpp:26:45: error: call of overloaded ‘bind(int (Class::*)(int, int), Class*, int, int)’ is ambiguous

私は次に何をすべきか、それが過負荷の問題だが、知っているヘッダファイルが自動的に含まれていますか?
それは動作します、ありがとう – neurobot
