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

execve("./bin/svn", ["./bin/svn"], [/* 22 vars */]) = 0

uname({sys="Linux", node="cq01-testing-img12.vm.baidu.com", ...}) = 0

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
