ubuntu下安装QT交叉编译环境

请问各位，安装qt 4.7.3版本的时候，make出现很多undefine 的错误是为啥？缺少公共库吗？错误如下

有可能是交叉编译器路径不对

vi ~/.bachrc
//加入
export PATH=$(交叉编译器的路径):$PATH

环境变量没有配置好，也缺钱依赖库

参考一下：

在Ubuntu 下的安装QT_alex_xhl的博客-CSDN博客_unbuntu安装qt Ubuntu 11.04下安装QT可以通过两种方式来安装，一种是直接安装QT的sdk包，其中继承了qt designer，qt库文件等。另一种方式是下载qt的源码包，然后编译安装。第一种方法http://qt.nokia.com/downloads 下载相应的版本，比如说是linux32位的。第二种方法下载源码包，比如最新的http://qt.nokia.com/downloads https://blog.csdn.net/alex_xhl/article/details/8949876

重新安装，把安装选项都选上，安装即可
