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 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!”
