Currently, there are 3 ways to install Gentoo, each having their own advantages and disadvantages:
  
−
*Gentoo stage: http://torindel.sezamkowa.net/openmoko/armv4tl-softfloat-linux-gnueabi/~arm/
+
* [http://gentoo.mindzoo.de/index.cgi/wiki/cross-compiling Cross compile approach], where you use another machine to compile your whole phone system. (Requires a Gentoo machine)
−
*Portage snapshot: look for mirror on: http://www.gentoo.org/main/en/mirrors2.xml and get snapshots/portage-DATE.tar.bz2
+
−
*Kernel and modules
+
−
*Any working Openmoko distro
+
  
 +
* [http://gentoo.mindzoo.de/index.cgi/wiki/native-compiling Native compilation approach], where you work with Gentoo on phone as with a normal system fully capable of installing its own packages.
  
−
== Installation ==

* [http://gentoo.mindzoo.de/index.cgi/wiki/qemu-user qemu-user emulated native compilation], where you use another machine 'chroot' into a gentoo filesystem (created by either of the methods above) and execute ARM binaries as if they were native executables.

[edit] Gentoo on Openmoko phones

Gentoo project on Openmoko phones has its own homepage: http://gentoo.mindzoo.de/

We have a portage overlay and some Openmoko packages like Xglamo, Illume or Zhone already have their ebuilds and many more will follow !

[edit] Ways to work with Gentoo

Currently, there are 3 ways to install Gentoo, each having their own advantages and disadvantages:

  • Cross compile approach, where you use another machine to compile your whole phone system. (Requires a Gentoo machine)
  • Native compilation approach, where you work with Gentoo on phone as with a normal system fully capable of installing its own packages.
  • qemu-user emulated native compilation, where you use another machine 'chroot' into a gentoo filesystem (created by either of the methods above) and execute ARM binaries as if they were native executables.
NOTE:

Many thanks go to 'torindel' who apparently started the effort and made a stage tarball we are using even today for the native approach and to Tuxxx who contributed strongly to the cross compilation efforts on gentoo for openmoko phones.

Needed things


Installation

  1. Partition your sd card if needed (don`t make swap partitions, ensure card isn't mounted): 
    2.  fdisk /dev/mmcblk0
  2. Make ext2 or ext3 filesystem: 
    3.  mkfs.ext2 /dev/mmcblk0p1
  3. Mount partition: 
    4.  mount /dev/mmcblk0p1 /media/card
  4. Copy stage and portage from host to moko (e.g. on localhost): 
    5.  scp stage3-armv4tl-*.tar.bz2 portage-*.tar.bz2 root@openmoko:/media/card
  5. Unpack stage and portage: 
    6.  tar -xjpf /media/card/stage3-armv4tl-*.tar.bz2 -C /media/card
 tar -xjpf /media/card/portage-*.tar.bz2 -C /media/card/usr
  6. Cleanup removing tar.bz2: 
    7.  rm /media/card/stage3-armv4tl-*.tar.bz2 /media/card/portage-*.tar.bz2
  7. Chroot: 
    8.  chroot /media/card /bin/bash

    9.  source /etc/profile; env-update
  9. Set timezone: 
    10.  cp /usr/share/zoneinfo/YOURZONE /etc/localtime
  10. Set hostname: 
    11.  nano /etc/conf.d/hostname
  11. Remove console font changing (small is beautiful ;]): 
    12.  rc-update del consolefont boot
  12. Setup fstab: 
    13.  nano /etc/fstab
  13. Edit inittab (hash out c3, c4, c5, c6, s0, s1 lines): 
    14.  nano /etc/inittab
  14. Setup usb networking: 
    15.  echo "modules=\"g_ether\"" >> /etc/conf.d/modules
 ln -s /etc/init.d/net.lo /etc/init.d/net.usb0
 echo "config_usb0=\"192.168.0.202 netmask 255.255.255.0\"" > /etc/conf.d/net
 echo "routes_usb0=\"default via 192.168.0.200\"" >> /etc/conf.d/net
 echo "nameserver 192.168.0.200" > /etc/resolv.conf
  15. Enable sshd: 
    16.  rc-update add sshd default
  16. Change root password: 
    17.  passwd
  17. Leave chroot: 
    18.  exit
  18. Copy kernel.
  19. Copy modules.
  20. Setup uboot for booting from sd card.
  21. Reboot.
  22. Setup/emerge rest of the system.

    23. Emerging binary packages

    • Binary package sites
    http://tinderbox.dev.gentoo.org/embedded/openmoko/armv4tl-softfloat-linux-gnueabi/
    http://torindel.sezamkowa.net/openmoko/armv4tl-softfloat-linux-gnueabi/~arm/packages/All
    • Add PORTAGE_BINHOST to make.conf
    e.g. 
    echo "PORTAGE_BINHOST=\"http://torindel.sezamkowa.net/openmoko/armv4tl-softfloat-linux-gnueabi/~arm/packages/All\"" >> /etc/make.conf
    • Update environment
    e.g. 
    source /etc/profile; env-update
    • Setup install mask if you don't want compiler headers/docs etc (mask headers only if you'll be always using binary packages)
    e.g. 
    export INSTALL_MASK="*.h"
    • Emerge packages with -kG
    e.g. 
    emerge -kG syslog-ng

    Binary package wishlist

    As i'll be adding some packages to ftp above you might want to ask for some package here: GentooPackageWishList
    Overlay with moko things and more packages coming soon.
