0 Preface

Previously, cross-compiling was established on Fedora 64bit, but since the 4.4.3 version required another GDB tool for Gdb-server debugging, and it took a long time, multiple GDB versions were error-filled. or a 32bit system.

The arm-linux-gcc4.4.2 of the friendly arm has been integrated with GDB without the need to reinstall GDB

1 Install arm-linux-gcc-4.3.21.1 put arm-linux-gcc-4.3.2.tgz in Home/hy/arm directory

1.2 Unzip the file, note that the-C is uppercase, change the meaning of the extracted directory, C, followed by a space, plus a root directory symbol/

[Email protected] arm]$ tar xvzf arm-linux-gcc-4.3.2.tgz-c/

1.3 Add the system environment variable, because you want to modify the file under/etc, you need root

[email protected] arm]$ su Password: [[email protected] arm]# Vi/etc/profile

Add a path to the last line of the profile and save the exit:

# #hy Add 3.22export path= $PATH:/usr/local/arm/4.3.2/bin#

1.4 Make the file effective immediately without restarting Fedora:

[Email protected] arm]# Source/etc/profile

Note: When switching back to a normal user, such as HY users, you may need to re-make the file effective source/etc/profile.

1.5 Check the version, the following instructions are installed successfully

 2 Configuring Server for NFS
Virtual machine share files to target machine, set up VMware setting->network-> bridged
The IP settings for the host and Target are on the same network segment.
2.1 Create a shared folder and set permissions
[Email protected] ~]$ mkdir/home/hy/nfsshare[[email protected] ~]$ chmod 777-r nfsshare/
2.2 Adding shares
[Email protected] hy]# Vim/etc/exports
/home/hy/nfsshare * (Sync,rw,no_root_squash)
To view shared folders
[[email protected] hy]# showmount-eexport list for Localhost.localdomain:/home/hy/nfsshare *
When the list of shared files appears, the NFS configuration of the host is correct. If it is an error, check the NFS status and firewall.
Check the Status of NFS
[Email protected] ~]$ systemctl status Nfs.service
Turn on NFS Services
[[Email protected] hy]# Service NFS startredirecting to/bin/systemctl start  nfs.service
Stop, start the firewall
[[email protected] init.d]# systemctl stop firewalld.service[[email protected] init.d]# systemctl start Firewalld.service
Disable the firewall,
[Email protected] init.d]# systemctl disable Firewalld.service
2.3 Target Machine Mount shared folder
The target Mount command is as follows, note that IP is the IP address of the host and is in the same network segment:
[Email protected]/]# mount-t nfs-o nolock 192.168.1.8:/home/hy/nfsshare//mntmount:rpc:unable to receive; errno = No route to host
Mount The Times wrong, then check the host's Firewall and NFS status.
After the Mount succeeds, the shared file can be seen in the/mnt/directory of the target machine
