QTE 重载了paintEvent（）后报错 line 1: syntax error: "(" unexpected

求教：
QT：4.5.3
QTE：4.5.3
编译环境：arm-none-linux-gnueabi-g++
我在PC机把程序交叉编译后，下载到ARM中去后，程序运行正常。但是一旦代码中重载了paintEvent（）后，就会报错：line 1: syntax error: "(" unexpected 。求教这是为什么呢？难道是库文件不全，还是版本有问题？
烦请指教！

我做了个空的Dialog，ARM能显示，但是我一旦画图形，就报错了。
代码如下：
//main.cpp
#include <QApplication>
#include "draw.h"

int main(int argc, char **argv)
{
QApplication app(argc, argv);
Draw *dialog = new Draw;
dialog->show();

app.connect( &app, SIGNAL( lastWindowClosed() ), &app, SLOT( quit() ) );

app.exec();
}
//Draw.h
#ifndef DRAW_H
#define DRAW_H

#include <QTimer>
#include <QDialog>
#include "ui_drawpic.h"

class Draw : public QDialog, public Ui_Dialog
{
Q_OBJECT
public:
Draw( QDialog *parent=0, Qt::WindowFlags f=0 );

protected:
void paintEvent(QPaintEvent *event);

};

#endif

//draw.cpp
#include "draw.h"

#include <QDialog>
#include <QPainter>

using namespace std;

Draw::Draw( QDialog *parent, Qt::WindowFlags f ) : QDialog( parent, f )
{
setupUi(this);
}
void Draw::paintEvent(QPaintEvent *)
{
QPainter painter(this);
painter.setRenderHint(QPainter::Antialiasing, true);
painter.setPen(QPen(Qt::black,1,Qt::DashDotLine, Qt::RoundCap));
// painter.setBrush(QBrush(Qt::green),Qt::SolidPattern);
painter.drawEllipse(0,0,200,240);/**/

painter.setPen(QPen(Qt::blue,1,Qt::DashDotLine, Qt::RoundCap));
painter.drawRect(0,0,this->width(),this->height());

painter.end();

}
