TQ2440实现触摸屏和qt图形 解决segmentation fault

使用触摸屏，首先安装触摸屏矫正程序。

下载并解压tslib-1.4，进入主目录，执行：

1 [root@localhost ~]#./autogen.sh
2 [root@localhost ~]#echo "ac_cv_func_malloc_0_nonnull=yes" >arm-none-linux-gnueabi.cache
3 [root@localhost ~]#./configure --host=arm-linux --cache-file=arm-linux.cache --prefix=/安装目录
4 [root@localhost ~]#make
5 [root@localhost ~]#make install

解压后进入目录，首先使用configure配置并生成makefile文件，开始我是在挂载到ntfs分区中执行到，但是不成功，也有可能是目录中有中文到原因，后来直接拷贝到Centos家目录，执行成功

 [root@localhost ~]#./configure -prefix （想要将qte安装到哪）-embedded arm -release -shared -fast -no-largefile -qt-sql-sqlite
