Glinux 1395 build ENV setup

1.安装ubuntu 14.04.05 LTS 64bit

2.初始化root 密码

sudo passwd 

Password: <--- 输入安装时那个用户的密码 

Enter new UNIX password: <--- 新的Root用户密码 

Retype new UNIX password: <--- 重复新的Root用户密码 

passwd：已成功更新密码

2.更新源

vi /etc/apt/sources.list 

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

sudo apt-get update

3.安装ssh 并设置，开机ssh 登陆

sudo apt-get install openssh-server

打开"终端窗口"，输入"sudo ps -e |grep ssh"-->回车-->有sshd,说明ssh服务已经启动，如果没有启动，输入"sudo service ssh start"-->回车-->ssh服务就会启动

使用gedit修改配置文件"/etc/ssh/sshd_config"

打开"终端窗口"，输入"sudo gedit /etc/ssh/sshd_config"-->回车-->把配置文件中的"PermitRootLogin without-password"加一个"#"号,把它注释掉-->再增加一句"PermitRootLogin yes"-->保存，修改成功

4.安装插件包

sudo apt-get update
sudo apt-get install git-core
sudo apt-get install subversion
sudo apt-get -y install git-core git-doc git-gui gitk 
sudo apt-get install u-boot-tools libssl-dev gawk gnupg flex bison gperf build-essential zip
curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386
libreadline6-dev:i386 libgl1-mesa-dev:i386 g++-multilib mingw32 tofrodos
python-markdown libxml2-utils xsltproc zlib1g-dev:i386 libxext-dev:i386 ruby
chrpath texinfo libswitch-perl ccache gcc-multilib libc6-dev-i386
lib32ncurses5-dev lib32z-dev unzip

gcc,g++

因为buildroot 2018 需要使用gcc ,g++ 5x ,所以如果环境中gcc，g++ 是4x 的可以参考如下升级

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update

安装依赖的包（出现错误才需要这个）

sudo apt-get install software-properties-common

升级安装

sudo apt-get install gcc-5 g++-5

之后更新gcc g++ link

sudo update-alternatives  --install  /usr/bin/gcc gcc /usr/bin/gcc-5 50
sudo update-alternatives  --install  /usr/bin/gcc-ar gcc-ar /usr/bin/gcc-ar-5 50
sudo update-alternatives  --install  /usr/bin/gcc-ranlib gcc-ranlib /usr/bin/gcc-ranlib-5 50
sudo update-alternatives  --install  /usr/bin/gcc-nm gcc-nm /usr/bin/gcc-nm-5 50
sudo update-alternatives  --install  /usr/bin/g++ g++ /usr/bin/g++-5 50
sudo update-alternatives  --install  /usr/bin/cpp cpp /usr/bin/cpp-5 50

检查config ,结果可看到都是 * 选中5x 版本即可

sudo update-alternatives  --config  gcc
sudo update-alternatives  --config  g++
sudo update-alternatives  --config  cpp

如需手动安装gcc5.x
