1 安装arm-linux-gcc-4.3.2
2 配置 nfs 服务器
之前在 fedora 64bit 上建立交叉编译，但由于4.4.3版本需要另装用于gdb-server调试的gdb工具，而且折腾了很久，多个gdb版本都报错。还是乖乖用32bit的系统。
友善之臂提供的arm-linux-gcc4.4.2已经集成了 gdb，不用重新安装gdb
[hy@localhost ARM]$ tar xvzf arm-linux-gcc-4.3.2.tgz -C /
[hy@localhost ARM]$ su Password: [root@localhost ARM]# vi /etc/profile
在profile的最后一行添加路径，保存退出 :
##hy add 3.22 export PATH=$PATH:/usr/local/arm/4.3.2/bin #
[root@localhost ARM]# source /etc/profile
注：在切换回普通用户时，如:hy 用户时，可能需要重新使文件生效 source /etc/profile。

检查arm-linux-gdb -v

虚拟机共享文件给目标机，设置Vmware setting->Network-> Bridged
主机和目标机的IP设置在同一网段。
[hy@localhost ~]$ mkdir /home/hy/nfsshare [hy@localhost ~]$ chmod 777 -R nfsshare/
[root@localhost hy]# vim /etc/exports
/home/hy/nfsshare *(sync,rw,no_root_squash)
查看共享的文件夹
[root@localhost hy]# showmount -e Export list for localhost.localdomain: /home/hy/nfsshare *
出现共享的文件列表时，说明主机的 nfs 配置正确。如果报错，请检查 nfs 状态和防火墙。
检查nfs的状态
[hy@localhost ~]$ systemctl status nfs.service
开启nfs服务
[root@localhost hy]# service nfs start Redirecting to /bin/systemctl start nfs.service
停止,开始防火墙
[root@localhost init.d]# systemctl stop firewalld.service [root@localhost init.d]# systemctl start firewalld.service
禁用防火墙,
[root@localhost init.d]# systemctl disable firewalld.service
目标机挂载命令如下，注意IP为主机的IP地址，且在同一网段：
[root@FriendlyARM /]# mount -t nfs -o nolock 192.168.1.8:/home/hy/nfsshare/ /mnt mount: RPC: Unable to receive; errno = No route to host
挂载时报错错，这时应检查主机的防火墙和 nfs 的状态。
挂载成功后，在目标机的 /mnt/目录下，就可看到共享的文件
