• $cd /home/yourname
• $mkdir slug

Place all of the downloaded files into this directory and extract them. Either by right clicking and choosing extract OR

• $ gunzip –d name followed by $ tar –xfv name

Monotone

Monotone will not install without other dependencies. Run the following:

• $ sudo apt-get install autoconf
• $ sudo apt-get install automake
• $ sudo apt-get install gettext
• $ sudo apt-get install libboost-dev
• $ sudo apt-get install libz-dev
• $ sudo apt-get install g++

Run the commands:

• $ sudo apt-get install boost_1_38_0
• $ sudo apt-get install python
• $ sudo apt-get install make
• $ sudo apt-get install subversion
• $ sudo apt-get install psycho OR
• $ sudo ./setup.py install
• $sudo apt-get install mtn-0.42-linux-x86

To Configure Monotone:

Create a configure script in /home/yourname/slug if one is not created. Include the following lines in the script:

$aclocal-1.9&&autoreconf –install $AUTOMAKE=automake-1.9 ACLOCAL=aclocal-1.9 autoreconf install

Download automake1.9 (if not installed) from [5] Extract and run

• $sudo apt-get install automake1.9

Then run

• $sudo ./configure

To fetch the monotone sources run:

• mtn --db=mt.mtn db init
• mtn --db=mt.mtn pull monotone.ca “net.venge.monotone*”
• mtn --db=mt.mtn --branch=net.venge.mnotone checkout monotone-sources

Getting Bitbake

You can either download bitbake from: [6]

OR go into /home/yourname/slug and run:

• $sudo mkdir bitbake
• $cd bitbake
• $sudo svn co svn://svn.berlios.de/bitbake/branches/bitbake-1.4 bitbake

Additional help can be found at

[7] If you downloaded bitbake, then save and extract the files in /home/yourname/slug cd into the bitbake directory You can either run:
• $sudo apt-get install bitbake OR
• $ sudo ./setup.py install --prefix=/usr/local

Run the following:

• $sudo mkdir openembedded
• $cd openembedded
• $sudo mkdir packages
• $cd packages
• $sudo mkdir file
• $cd file

Create the following files

Set-env

OEROOT="/home/yourname/slug" OESYS=$OEROOT/bitbake-1.8.12 PKGDIR=$OEROOT/openembedded OEBUILD=$OEROOT/build BBPATH=$OEBUILD:$PKGDIR:$OESYS PATH=$OESYS/bin:$PATH cd $OEBUILD LD_LIBRARY_PATH= export PATH LD_LIBRARY_PATH BBPATH export LANG=C unset LC_CTYPE unset CC unset CXX alias bb=bitbake echo "Environment set up for OpenEmbedded development."

Local.conf

OEROOT = "/home/yourname/slug" DL_DIR = "${OEROOT}/sources" BBFILES = ${OEROOT}/bitbake-1.8.12/openembedded/packages/*/*.bb BBPATH = ${OEROOT}/bitbake-1.8.12 OEMASK = "" PREFERRED_PROVIDERS = " virtual/${TARGET_PREFIX}gcc-initial:gcc-cross-initial" PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}gcc:gcc-cross" PREFERRED_PROVIDERS += " virtual/${TARGET_PREFIX}g++:gcc-cross" MACHINE = "nslu2" DISTRO = "unslung" OEINCLUDELOGS = "yes"

Hello-1.0.bb

DESCRIPTION = "hello world sample program"PR = "r0"DEPENDS = ""SRC_URI = "file://hello.c"S = "${WORKDIR}"do_compile () { ${CC} ${CFLAGS} ${LDFLAGS} -o hello hello.c}do_install () { install -d ${D}${bindir}/ install -m 0755 ${S}/hello ${D}${bindir}/}FILES_${PN} = "${bindir}/hello"

Hello.c

1. include "stdio.h“

main() {

 printf("Hello World\n");

}

Where to put the files:

• /home/yourname/slug/set-env
• /home/yourname/slug/bitbake-1.8.12/openembedded/packages/hello-1.0.bb
• /home/yourname/slug/bitbake-1.8.12/openembedded/packages/file/hello.c
• /home/yourname/slug/bitbake-1.8.12/conf/local.conf

In the bitbake.conf file – located in the conf folder, ensure that OEDIR is set to: /home/yourname/slug Also ensure that you change the path in the files you just created to match your directory structure

In /home/yourname/slug run:

• $sudo ./set-env

This sets up the openembedded environment which is needed to finish running everything from bitbake

Building Hello World<H2> Once all files are in the correct place and the dependencies are installed, run the following:

• $cd /home/yourname/slug/bitbake-1.8.12/openembedded/packages
• $bitbake world OR
• $bitbake –b hello

World will build everything in the folder -b hello will only build the hello package

• $sudo apt-get install hello
• $hello

This will print out “hello world!”
