QtConcurrent错误：用作初始化程序的数组

Question

我是Qt的新手，我需要为下面的成员函数使用另一个线程

int length=interface->get_message(channelnumber_uint, &identifier, message, &can_flag_uint, timeout_uint);

我尝试过：

QFuture <int> future = QtConcurrent::run(interface, &can_handler::get_message, channelnumber_uint, &identifier, message, &can_flag_uint, timeout_uint);
int length = future.result();

im在qtconcurrentfunctioncall.h中出现错误

/usr/include/x86_64-linux-gnu/qt5/QtConcurrent/qtconcurrentstoredfunctioncall.h:1200: error: array used as initializer
     : fn(_fn), object(_object), arg1(_arg1), arg2(_arg2), arg3(_arg3), arg4(_arg4), arg5(_arg5){ }
                                                                                               ^

我看到有人只是使用std :: array而不是unsigned char数组，但是我不允许更改它。还有其他解决方案吗？

整个（我切断了不相关的代码）：

void MainWindow::on_pushButton_canreceivemessage_clicked()
        {
        QString channelnumber_qstr, timeout_qstr;
        unsigned int channelnumber_uint, timeout_uint, can_flag_uint, identifier, length;
        unsigned char message[8];

        channelnumber_qstr=ui->lineEdit_cancommunicationchannel->text();
        timeout_qstr=ui->lineEdit_cantimeoutreceive->text();
        channelnumber_uint = channelnumber_qstr.toUInt(&ok, 10);            
        timeout_uint = timeout_qstr.toUInt(&ok,10);

        //the function that has to be called from another thread  
        //int length=interface->get_message(channelnumber_uint, &identifier, message, &can_flag_uint, timeout_uint);

         QFuture <int> future = QtConcurrent::run(interface, &can_handler::get_message, channelnumber_uint, &identifier, message, &can_flag_uint, timeout_uint);
         int length = future.result();
         }

我使用了包装函数：

int MainWindow::get_message_thread(int channel_number, unsigned int * identifier, string message_str, unsigned int * flag, unsigned int timeout)
    {
        unsigned char message_uch[8];

        int length=interface->get_message(channel_number, identifier, message_uch, flag, timeout);

         stringstream s;
         s << message_uch;
         message_str = s.str();
        return length;
    }

整个：

QString channelnumber_qstr, timeout_qstr;
        unsigned int channelnumber_uint, timeout_uint, can_flag_uint, identifier, length;
        string message;

        channelnumber_qstr=ui->lineEdit_cancommunicationchannel->text();
        timeout_qstr=ui->lineEdit_cantimeoutreceive->text();
        channelnumber_uint = channelnumber_qstr.toUInt(&ok, 10);            
        timeout_uint = timeout_qstr.toUInt(&ok,10);

QFuture <int> future = QtConcurrent::run(this, &MainWindow::get_message_thread, channelnumber_uint, &identifier, message, &can_flag_uint, timeout_uint);

    int length = future.result();
