| − | Installing and Running
| + | <H1>Question / Comments</H1> |
| − | Hello World
| + | |
| − | By
| + | |
| − | Sarah Pramanik
| + | |
| − | | + | |
| − | Getting Started
| + | |
| − | | + | |
| − | Download Ubuntu from:
| + | |
| − | [http://www.ubuntu.com/getubuntu/download]
| + | |
| − | Burn ISO Image to a disk
| + | |
| − | Put Disk into machine of your choice
| + | |
| − | (These examples are run on an Acer Aspire Model: KAW60)
| + | |
| − | Install Ubuntu from Disk
| + | |
| − | | + | |
| − | Once Ubuntu is up and running Type:
| + | |
| − | $ sudo passwd
| + | |
| − | $ yourpassword
| + | |
| − | Configure internet access using:
| + | |
| − | $ ifconfig eth0 xxx.xxx.xxx.xxx
| + | |
| − | OR $ net-setup
| + | |
| − | Note: On the Acer, Ubuntu automatically connected
| + | |
| − | Note: Every command run with sudo will require yourpassword in order to run
| + | |
| − | | + | |
| − | | + | |
| − | Dependencies
| + | |
| − | There are a couple of dependencies which must be installed first:
| + | |
| − | Monotone (or bitkeeper, but I used monotone)
| + | |
| − | This requires that Boost is installed
| + | |
| − | Pyscho JIT Compiler
| + | |
| − | Python compiler (should come with OS)
| + | |
| − | Download These from
| + | |
| − | [http://www.monotone.ca/]
| + | |
| − | [http://psyco.sourceforge.net/]
| + | |
| − | [http://www.boost.org/users/download/]
| + | |
| − | | + | |
| − | | + | |
| − | Create a directory under your home directory called slug
| + | |
| − | 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
| + | |
| − | | + | |
| − | Configuring
| + | |
| − | 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 [http://www.filewatcher.com/m/automake-1.9.6.tar.bz2.765505.0.0.html]
| + | |
| − | 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:
| + | |
| − | [http://developer.berlios.de/projects/bitbake/]

| + | |
| − | $sudo svn co svn://svn.berlios.de/bitbake/branches/bitbake-1.4 bitbake
| + | |
| − | Additional help can be found at
| + | |
| − | [http://bitbake.berlios.de/manual/]
| + | |
| − | 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
| + | |

| − | OEROOT = "/home/yourname/slug"
| + | |
| − | DL_DIR = "${OEROOT}/sources"
| + | |
| − | BBFILES = ${OEROOT}/bitbake-1.8.12/openembedded/packages/*/*.bb

| − | 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
| + | |
| − | #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 run: $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!”
| + | |
