svn安装在了tools目录外面，把文件夹移动tools/下的时候，发现svn不能用了，报错
error while loading shared libraries: libsvn_client-1.so.0: cannot open shared object file: No such file or directory
1、之前出现过这样的问题，大师教招：strace。于是用strace svn跑了下，发现
strace ./bin/svn

修改了bashrc中的path变量，加入这个路径还是有问题。只能请教大师
2、大师招数1——ldd命令查看 so文件，发现so not found
libsvn_client-1.so.0 => not found
libsvn_wc-1.so.0 => not found
3、大师招数2——查看LD_LIBRARY_PATH变量
发现是空的
于是传授入下
1）LD_LIBRARY_PATH变量设置上svn的lib路径
于是在~/.bashrc里面加入了
“export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/tools/”
source ~/.bashrc后解决
