Ubuntu12.04安装Freescale LTIB环境

Ubuntu12.04安装Freescale LTIB环境

    最近手上拿到一块imx6s的板子，打算先看看linux下相关的开发调试方法。初步了解了下，linux下开发freescale采用的LTIB这个东西，所以不得不先看看这个。以下是搭建ltib的基本步骤，在此做一个记录。

1 配置Ubuntu源

#sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak (backup original file)
#sudo gedit /etc/apt/sources.list

添加如下：

//Delete all item in this file, then copy the following server addresses to it :
deb http://mirrors.163.com/ubuntu/ precise main restricted
deb-src http://mirrors.163.com/ubuntu/ precise main restricted
deb http://mirrors.163.com/ubuntu/ precise-updates main restricted
deb-src http://mirrors.163.com/ubuntu/ precise-updates main restricted
deb http://mirrors.163.com/ubuntu/ precise universe
deb-src http://mirrors.163.com/ubuntu/ precise universe
deb http://mirrors.163.com/ubuntu/ precise-updates universe
deb-src http://mirrors.163.com/ubuntu/ precise-updates universe
deb http://mirrors.163.com/ubuntu/ precise multiverse
deb-src http://mirrors.163.com/ubuntu/ precise multiverse
deb http://mirrors.163.com/ubuntu/ precise-updates multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-updates multiverse
deb http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-backports main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ precise-security main restricted
deb-src http://mirrors.163.com/ubuntu/ precise-security main restricted
deb http://mirrors.163.com/ubuntu/ precise-security universe
deb-src http://mirrors.163.com/ubuntu/ precise-security universe
deb http://mirrors.163.com/ubuntu/ precise-security multiverse
deb-src http://mirrors.163.com/ubuntu/ precise-security multiverse
deb http://extras.ubuntu.com/ubuntu precise main
deb-src http://extras.ubuntu.com/ubuntu precise main

保存退出，更新源：

#sudo apt-get update

2 修改 Sudoers
执行如下命令：

sudo /usr/sbin/visudo

在 User privilege specification， root ALL=(ALL) ALL  后面加入（强调一下 ubuntu 是 usrname ）：

ubuntu ALL = NOPASSWD: /usr/bin/rpm, /opt/freescale/ltib/usr/bin/rpm

3：安装必要的pakages：

sudo apt-get install aptitude

可以使用以下脚本执行pakage的安装：

#!/bin/bash  
# Install packages needed by LTIB  
sudo aptitude -y install gettext libgtk2.0-dev rpm bison m4 libfreetype6-dev  
sudo aptitude -y install libdbus-glib-1-dev liborbit2-dev intltool  
sudo aptitude -y install ccache ncurses-dev zlib1g zlib1g-dev gcc g++ libtool  
sudo aptitude -y install uuid-dev liblzo2-dev  
sudo aptitude -y install tcl dpkg  
sudo aptitude -y install asciidoc texlive-latex-base dblatex xutils-dev  
# Packages required for 64-bit Ubuntu  
# Do "uname -a" and see if the word "x86_64" shows up.  
if uname -a|grep -sq 'x86_64'; then  
sudo aptitude -y install ia32-libs libc6-dev-i386 lib32z1  
fi  
# The following recommended for Linux development.  
# They are not required by LTIB.  
sudo aptitude -y install gparted emacs22-nox openssh-server  
sudo aptitude -y install nfs-common nfs-kernel-server lintian  
sudo aptitude -y install git-core git-doc git-email git-gui gitk  
sudo aptitude -y install diffstat indent tofrodos fakeroot doxygen uboot-mkimage  
sudo aptitude -y install sendmail mailutils meld atftpd sharutils  
sudo aptitude -y install manpages-dev manpages-posix manpages-posix-dev linux-doc  
sudo aptitude -y install vnc4server xvnc4viewer  
sudo aptitude -y install texinfo  

保存执行此脚本即可。

4：安装编译

  （1）移走之前所有安装在/opt/freescale/pkgs下的包

  （2）安装LTIB package

              解压源码包带有ltib环境的源码包 (可以从freescale官网下载)

            在源码包下执行： ./install 命令 （期间需要输入两次“yes”确认）

             选择安装的路径
 
 ps：对于Ubuntu12.04.在编译之前需做如下设置（在安装的LTIB目录下运行如下脚本）：

#!/usr/bin/env bash 
   
# get the patch tarball and untar it  
wget -O ubuntu-ltib-patch.tgz https://community.freescale.com/servlet/JiveServlet/downloadBody/93454-102-3-2834/ubuntu-ltib-patch.tgz  
tar -xzvf ubuntu-ltib-patch.tgz  
      
# execute the script which do the patching  
ltibDir=`pwd`  
cd ubuntu-ltib-patch  
./install-patches.sh $ltibDir  

5 编译
 在编译之前，可以运行如下命令进行配置：

./ltib -m config

主要配置你所使用的板卡，u-boot，kernel版本等，同时也可以通过图形界面的方式在编译过程中配置。
编译采用如下命令：

./ltib

6 编译过程中可能出现的问题：
 出现failed buding busybox，这时候要执行如下操作：

1）在 /usr/include下创建一个软链接：

sudo ln -s i386-linux-gun/sys sys

2）修改 ltib/dist/lfs-5.1/base_libs/base_libs.spec（注释#部分）

...

perl -w -e '

# @ARGV = grep { `file $_` =~ m,ASCII C program text, } @ARGV;

# exit (0) unless @ARGV;
