关于QT程序中出现collect2: ld returned 1 exit status
不是专业做应用开发的，只是偶尔用Qt 写下工具，所以用的不怎么熟，经验也没，呵呵，碰到问题，只能一步一步慢慢找了，效率有点低。 先把问题截图贴出来 在之前也碰到过如”collect2: ld returned 1 exit status“这一类的问题，是因为我已经运行了一个程序
不是专业做应用开发的，只是偶尔用Qt 写下工具，所以用的不怎么熟，经验也没，呵呵，碰到问题，只能一步一步慢慢找了，效率有点低。
先把问题截图贴出来
在之前也碰到过如”collect2: ld returned 1 exit status“这一类的问题，是因为我已经运行了一个程序，这个程序没有关闭，再此调试或运行时qt 会报这样的错误。
这次却不同，我没有运行程序呀，在编译的时候还是会报这个错误，就纳闷了，调试了好久，终于找到问题了。
这次是我添加了一个继承与 QThread的类，可以说用了一个新线程吧。然后在类体中声明了 void run() 函数，但是我并没有在类外去实现void run()函数的定义，结果在编译的时候就报上面提示的错误了。
具体是什么原因，现在还不能做出完整正确的分析，时间有限，先把问题解决了吧！有哪位大神要是能帮忙分析下，就感谢了！
