触摸屏测试：Tslib（配置了一天，心累）
总结：网上有许多关于tslib的步骤/错误总结，所以这里只是提几个我觉得比较棘手的问题：
1,我明明给arm-linux-gcc配置了环境变量，为什么还是提示我说:arm-none-linux-gnueabi-gcc common not found？
我配置的时候是配置用户环境变量，而不是全局，改成全局这个提示就没有再出现了：就是说 往/etc/profile里面写 PATH （记得log out 或者重启一下）
2，输入make 会出现了这个错误：call to '__open_missing_mode' declared with attribute error: open with O_CREAT in second argument needs 3 arguments；
具体提示如下：

解决方法，没有找到直接的解决方法，这是另外一篇类似的错误：

也是提示：open with O_CREAT in second argument needs 3 arguments
根据上文博主的经验，我将ts_calibrate.c 中的open函数从两个参数输入变成三个，save之后输入命令make，终于在目标文件夹出现了4个文件夹，之前一直死活出不来bin文件夹
