Question

我正在尝试创建一个运行boost的asio的IO服务的线程。但是，我得到以下编译错误。有什么办法可以解决吗？

环境：gcc 4.7.2，提升1.54

error: left operand of comma operator cannot resolve address of overloaded function
error: invalid static_cast from type ‘boost::asio::io_service’ to type ‘size_t (boost::asio::io_service::*)() {aka long unsigned int (boost::asio::io_service::*)()}’

代码：

boost::asio::io_service oSer;
    std::thread t(std::bind(static_cast<size_t (boost::asio::io_service::*)()>(&boost::asio::io_service::run, oSer)));
    t.join();

Answer 1

如何使用lambda表达式？

std::thread t([&oSer](){ oSer.run(); });

如果你不喜欢使用lambda，试试这个

std::thread t(std::bind(static_cast<size_t(boost::asio::io_service::*)()>(&boost::asio::io_service::run), &oSer));

绑定boost的asio的编译错误
