现象：下载的开源的ptpd2.3.1的源代码 ，在本地服务器可以好好地编译通过，但是上传到svn的库上之后，再次check下来就编译不过，同样的配置和编译链，就是无法编译过？
定位思路如下：
上传和下载之前毫无差异，无法定位到具体是哪个目录的问题，在偶然的复制时候发现，复制的操作不一样会有不一样的结果，最后定位到文件的时间问题，但是svn的文件修改时间是系统的时候，所以最后修改为check下来之后修改一下文件的修改时间，命令如下：
touch -t "201507290101" //年月日时分
编译错误如下：

If you have problems, you may need to regenerate the build system entirely.
To do so, use the procedure documented by the package, typically 'autoreconf'.
