回复：linux串口程序如何与我设计的人机界面结合
最近正在开发一个linux下串口程序，环境ubuntu，我不明白串口程序如何与我设计的人机界面结合？直接在 qt designer中写串口程序（c语言）？好像没法编译!我不知道是我qt designe版本的问题还是什么原因？一编译就出错，说是找不到文件，明明那个文件在的.
qt designer中没有串口通信的类.

为啥没有理会呢？？

回复: linux串口程序如何与我设计的人机界面结合
将linux下串口通信程序嵌入qt designer设计的界面，编译出了很多问题！
郁闷之至！我是将这些头文件直接包含在主界面窗口类的.h文件中的！
#include <stdio.h> /*标准输入输出定义*/
#include <stdlib.h> /*标准函数库定义*/
#include <unistd.h> /*Unix 标准函数定义*/
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h> /*文件控制定义*/
#include <termios.h> /*PPSIX 终端控制定义*/
#include <errno.h> /*错误号定义*/
谁能给个完整的 例子看看？
同情下初学者吧！！
