本文介绍了解决libnl库拷贝过程中遇到的问题，由于目标SD卡采用fat32格式，不支持软链接，因此采取了打包和解压的方法成功实现库文件的迁移。

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

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

void@void-ThinkPad-E450:/usr/local/arm/libnl3.4$ sudo tar -cjvf libnl.bz2 ./lib

void@void-ThinkPad-E450:/usr/local/arm/libnl3.4$ cp libnl.bz2 /media/void/0000-006F/
gcc-linaro.tar.bz2      lib/                    libnl-3.4.0.tar.gz      libnl-doc-3.4.0.tar.gz  trave/                  
void@void-ThinkPad-E450:/usr/local/arm/libnl3.4$ cp libnl.bz2 /media/void/0000-006F/ -v
‘libnl.bz2’ -> ‘/media/void/0000-006F/libnl.bz2’
void@void-ThinkPad-E450:/usr/local/arm/libnl3.4$ sync

void@void-ThinkPad-E450:/usr/local/arm/libnl3.4$ umount /media/void/0000-006F
void@void-ThinkPad-E450:/usr/local/arm/libnl3.4$
