colinuxi hope this is my last post on colinux and erlang, but although i had written several time about it, i will do it once more, to sum up a little guide to setup a new colinux with the correct way to set erlang on it. i also added few words on adding the nitrogen web framework.

> is used for windows command prompt
$ is used for linux shell prompt

ubuntu 8.04 server


  • direct download –
  • extract qemu into a new directory c:\linux\qemu
  • start windows command prompt
  • make a 3gb image:
     > fsutil file createnew c:\linux\distro\qemu_ubuntu_3gb 3221257728
  • make a image for a 512mb swap file:
     > fsutil file createnew c:\linux\distro\qemu_swap_512mb 536903168
  • on c:\linux\qemu create the next batch file: install.bat, whith the following content:
    set qemu_dir=C:\linux\distro
    set hd=%qemu_dir%\qemu_ubuntu_3gb
    set swap=%qemu_dir%\qemu_swap_512mb
    set cdrom=%qemu_dir%\ubuntu-8.04.2-server-i386.iso
    set mem=384
    qemu -hda %hd% -hdb %swap% -cdrom %cdrom% -m %mem% -boot d -L .
  • run the batch file you have just created: install.bat
  • go through the linux installation, select manually partition when asked, and do the following:
    • create new partitionchoose /dev/sda
    • choose create as: primary partition
    • choose file system: ext3
    • create new partitionchoose /dev/sdb
    • choose create as: primary partition
    • choose file system: linux-swap
  • install, and when you get to the point it asks for restart – you have finished. it takes some time, so be patient.


  • direct download –
  • run and install on c:\colinux
  • don’t use or download any of the suggested distributions on the install process
  • download and install unxutils –
  • convert qemu ubuntu image to colinux image
     > cd c:\linux\distro
     > dd if=qemu_ubuntu_3gb of=ubuntu_3gb.img bs=512 skip=63
  • you only need the file ubuntu_3gb.img the other 2 files (qemu_swap_512mb and qemu_ubuntu_3gb) can be removed
  • create new swap file:
     > fsutil file createnew c:\linux\distro\swap_512mb 536870912
  • create a file on c:\linux\distro named ubuntu8.04.conf, and paste the following into it:
    root=/dev/sda1 fastboot 3
  • create a shortcut for colinux-daemon.exe, right click on it and edit its properties, to add the following parameters (on the shortcut target field):
    c:\colinux\colinux-daemon.exe -t nt @c:\linux\distro\ubuntu8.04.conf
  • start this new shortcut, running the colinux the first time
  • edit /etc/network/interfaces and the windows tap connection, see my previous post named colinux
  • install ssh and update:
    $ sudo apt-get install ssh
    $ sudo apt-get update
    $ sudo apt-get upgrade
    $ chsh -s /bin/bash user_name
  • connect using putty to

compress and backup the colinux image

  • to determine the free space in megabytes
    $ df -m
  • fill image with zeros
    $ dd if=/dev/zero of=foobar bs=1M count='above result less 5'
    $ rm foobar
  • logout, and compress from windows using a compression app, should get around 100MB file

install erlang from source

$ sudo apt-get install build-essential
$ sudo apt-get install libncurses5-dev
$ sudo apt-get install m4
$ sudo apt-get install libssl-dev
$ sudo apt-get install openssl
$ cd; mkdir workspace; cd !
$ wget
$ tar xvfz otp_src_R12B-5.tar.gz
$ cd otp_src_R12B-5
$ ./configure
$ make
$ sudo make install

install some basics

$ sudo apt-get install git subversion ctags vim

setup environment

edit .bash_profile, and add the following at the bottom

export ERL_LIBS=${HOME}/erlang/lib

download and install nitrogen

$ cd; mkdir -p erlang/lib; cd !$
$ git clone git://
$ cd nitrogen
$ make
