最近在编译libnl库准备拷贝到其他机器中使用的时候出现无法拷贝问题，原因是sd卡是fat32文件系统格式，这种文件系统不支持linux下的ln软链接文件，
void@void-ThinkPad-E450:~/libnl-3.4.0$ sudo cp /usr/local/arm/libnl3.4/lib /media/void/0000-006F/ -rf cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-cli-3.so’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-3.so.200’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-3.so’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-route-3.so.200’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-genl-3.so’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-nf-3.so.200’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-xfrm-3.so’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-genl-3.so.200’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-idiag-3.so.200’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-xfrm-3.so.200’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-nf-3.so’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-route-3.so’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-idiag-3.so’: Operation not permitted cp: cannot create symbolic link ‘/media/void/0000-006F/lib/libnl-cli-3.so.200’: Operation not permitted
于是只好先将整个文件夹打包，拷贝到别的机器上后再次解压即可
