qt串口编程的问题

make后提示 serialthread.h 语法错误，但没发现serialthread.h中的语法错误。为什么编译不成功呢？？

[root@localhost qt-1]# make

g++ -c -pipe -DQWS -fno-exceptions -fno-rtti -Wall -W -O2 -fno-default-inline -DNO_DEBUG
-I/working/qt/qt-2.3.7/include -o mainwindow.o mainwindow.cpp

make: *** [mainwindow.o] Error 1


但没发现[serialthread.h]有什么语法错误
/* serialthread.h */

#ifndef SERIAL_THREAD_H
#define  SERIAL_THREAD_H
#include

class MainWindow;

class SerialThread: public QThread
{
public:
    SerialThread(MainWindow *parent);
    virtual void run();
private:
    MainWindow *parent;

};
#endif

这不是串口的问题，

是C++的用法问题，

头文件的定义，以及cpp文件中的引用方式可能有些问题。

检查一下环境变量配置好没有？include目录，lib目录这些路径有没有设置对。

解决啦，是添加多线程支持
不过还是谢谢大家！O(∩_∩)O~

请问你是如何解决的，我也遇到了同样的问题。郁闷中。。。
