qtu盘检测 linux,基于Qt的检测U盘移植arm--- was not provided by anyservice...

用Qt的dbus模块检测U盘插拔，最重要移植到tiny210开发板上。现在已经在pc上调试成功了，经过重重困难，在arm上移植了带dbus的qt的lib，dbus-1.0.2，在pc交叉编译的时候顺利通过，但就是运行的时候报错：

[root@FriendlyARM /ayan]# ./Esto-server -qws

111111111

22222222222

"?????????QDBusInterface?" "The name was not provided by any

.service files"

Object::connect: No such signal QDBusAbstractInterface::DeviceAdded(QString)

Object::connect: (receiver name: 'Widget')

Object::connect: No such signal QDBusAbstractInterface::DeviceRemoved(QString)

Object::connect: (receiver name: 'Widget')

我的源程序：

qDebug()<

QDBusInterface *dBusInterface = new QDBusInterface(DBUS_HAL_SERVICE,

DBUS_HAL_PATH,

DBUS_HAL_INTERFACE,

QDBusConnection::systemBus(),

this);

qDebug()<

if(!dBusInterface->isValid())

qDebug()<toUnicode("初始化错误，找不到QDBusInterface！")<<:systembus>

connect(dBusInterface, SIGNAL(DeviceAdded(QString)), this, SLOT(slotDeviceAdded(QString)));

connect(dBusInterface, SIGNAL(DeviceRemoved(QString)), this, SLOT(slotDeviceRemoved(QString)));

问题就出在两个信号的连接上！

这里提示The name was not provided by any

.service files是不是我的tiny210开发板不支持HAL？？我查看了一下，根目录下没有/org/.........这些目录。

是不是还要移植HAL？？这方便资料好少啊希望大家指点一下。。。。。。。。。。。
