EBC Exercise 16 git

git is a distributed revision control system with an emphasis on being fast. It was initially designed and developed by Linus Torvalds for Linux kernel development. The purpose of this lab is to get hands on experience with git to learn how it works and how to use it.

Much of the material here has come from Pro Git. We'll be using github to practice gitting.

Set Up Git

Go to github and following the directions for installing and setting up git. No need to set up your own repository right now (unless you want to), I already have one set up for you the play with.

I suggest you do this for both your host computer and your Beagle. On the Beagle use

opkg install git

Play with git locally

Pro Git has a nice on-line book with lots of good details. I'll lead you through many parts of it. The first chapter is Getting Started. Here are the topics:

1.1 - About Version Control
1.2 - A Short History of Git
1.3 - Git Basics
1.4 - Installing Git
1.5 - First-Time Git Setup
1.6 - Getting Help
1.7 - Summary

I'll cover Git Basics in class and you have already done parts 1.5 and 1.6 to set up for github. I suggest you take a look at Getting Help and then move on.

Nice git article

Here's a nice article on a common git workflow.

Access ti/staging

Here is what I did to access the ti/staging stuff.

host $ cd ~/oe/openembedded
host $ git remote add gitor git://gitorious.org/angstrom/openembedded.git
host $ git fetch gitor
host $ git checkout gitor/ti/staging -b ti/staging
host $ cd ${OETREE}
host $ wget http://download.berlios.de/bitbake/bitbake-1.8.18.tar.gz
host $ tar -xvf bitbake-1.8.18.tar.g
host $ gedit source-me.txt

Change

PATH=${OETREE}/openembedded/bitbake/bin:${ORG_PATH}

to

PATH=${OETREE}/bitbake-1.8.18/bin:${ORG_PATH}

Save and quit gedit

host $ . source-me.txt
host $ cd ~/oe
host $ mv angstrom-dev angstrom-dev.v0
host $ bitbake console-image
