使用busybox制作的根文件系统，没有ftp客户端工具，无法登录到其他的ftp服务器，需要自己编译ftp指令。 在这里采用源码包netkit-ftp-0.17.tar.gz编译，步骤如下： 1、tar解压 2、打补丁 patch -p1< netkit-ftp-0.17-cross.patch
 在源码目录下，建立上述名字的补丁文件，内容如下：

3、指定交叉编译工具，进行configure ./configure --with-c-compiler=arm-none-linux-gnueabi-gcc 
4、make make时可能出现以下错误： glob.c: In function 'ftpglob':
glob.c:126:15: error: 'ARG_MAX' undeclared (first use in this function)
glob.c:126:15: note: each undeclared identifier is reported only once for each function it appears in
glob.c: In function 'ginit':
glob.c:167:11: error: 'ARG_MAX' undeclared (first use in this function)
glob.c: In function 'Gcat':
glob.c:582:32: error: 'ARG_MAX' undeclared (first use in this function)
make[1]: *** [glob.o] 错误 1
make[1]:正在离开目录 `/home/am335x/package/netkit-ftp-0.17/ftp'
make: *** [ftp.build] 错误 2
 从网上查找解决方法如下： 修改glob.c,在#include “glob.h”添加： #if define (_POSIX_ARG_MAX)        #if define (ARG_MAX)      #undef ARG_MAX #endif #endif 但是经过实验，问题依然没有解决。 。。。。（待寻找正确、合理的方法解决）。。。。。
5、将编译的ftp指令上传到根文件系统，测试一下看看： ftp: error while loading shared libraries: libreadline.so.5: cannot open shared object file: No such file or directory
 ftp: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory
 ftp: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
 分别在交叉编译工具的库中找到上述3个库，拷贝到根文件系统的lib目录下。 接下来可以正常的从ftp服务器get想要的文件了。
