Question

编译qt可以在windows下面运行，但是在linux下编译为什么提示这样的错误呢？

Answer 1

还是使用QT SDK吧，编译出错看得一清二楚。关于QT的跨平台，国内很少有人去关注，其实实现源码项目的跨平台的关键就是一个文件：平台配置文件，一个你在编写代码时不会亲自去写的文件，QT SDK自动生成的文件，不同平台、相同程序会生成不同的配置文件，而那个配置文件就决定了程序编译时的环境。所以删除那个文件即可编译成功。究竟那个文件是谁？自己观察观察就OK了

Answer 2

你这怎么直接make？
首先确保你的qt装好了，最好通过源直接安装。比如： sudo apt-get install qt4.7
然后 编译一般先:
qmake -project
qmake
make

Answer 3

添加环境变量了吗？我怎么看见QT3.3，难道你装的是3.3版的？

追问

嗯 是啊 怎么添加环境变量啊？
