| − | == Overview ==
| |
| − | Gentoo armv4tl-softfloat-linux-gnueabi optimalized for Openmoko (-Os -march=armv4t -mtune=arm920t) on 2008.0/arm profile (glibc based, sane bootstrapable toolchain)<br>
| |
| − | (embedded uclibc/arm profile armv4tl-softfloat-linux-uclibcgnueabi in plans)

| | | | |
| − | [http://img46.imageshack.us/img46/646/80330048oy9.jpg Screenshot (hosted at ImageShack)] | + | Gentoo project on Openmoko phones has its own homepage: [http://gentoo.mindzoo.de/ http://gentoo.mindzoo.de/] |
| | | | |
| − | == Read first ==
| + | We have our own portage overlay and some Openmoko packages like Xglamo, Illume or Zhone already have theyr ebuilds. |

| | | | |
| | + | == Ways to work with Gentoo == |
| | + | Currently, there are 2 ways how to install gentoo, both having advantages and disadvantages: |
| | | | |
| − | == Needed things ==
| + | * Cross compile approach, where you use another machine to compile your whole phone system. |
| | | | |
| − | *At least 2GB SD card | + | * Native compilation approach, where you work with Gentoo on phone as with a normal system fully capable of installing its own packages. |
| − | *Gentoo stage: http://torindel.sezamkowa.net/openmoko/armv4tl-softfloat-linux-gnueabi/~arm/
| + | |
| − | *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
| + | |
| | | | |
| | | | |
| − | == Installation ==
| + | Many thanks go to 'torindel' who apparently started the effort and made a stage tarball we are using even today for the native approach. |
| − | === Be careful, the overlay seems to be dead, so you'll have to manually compile (please make ebuilds if you do) illume and anything openomoko-specific ===

| + | |
| − | *Update environment
| + | |
| − | :<tt>e.g.</tt> <pre>source /etc/profile; env-update</pre>
| + | |
| − | *Setup install mask if you don't want compiler headers/docs etc (mask headers only if you'll be always using binary packages)
| + | |
| − | :<tt>e.g.</tt> <pre>export INSTALL_MASK="*.h"</pre>
| + | |
| − | *Add the following line to make.conf to tell portage to always use binary packages. <pre>EMERGE_DEFAULT_OPTS="-gK"</pre>
| + | |
| − | | + | |
| − | == Alternative: Squashed Portage ==
| + | |
| − | An alternative to installing a full, writable, and uncompressed portage tree directly on the microSD card, is to compress portage using SquashFS and then to mount the resulting SquashFS file (usually compressed from about 500 MB to 50 MB) at /usr/portage.
| + | |
| − | | + | |
| − | In this case, it is also suggested to set DISTDIR to /tmp/distfiles, because the default DISTDIR (/usr/portage/distfiles) is not writable. Similarly, PKGDIR can be set to /tmp/binpkgs instead of the default /usr/portage/packages.
| + | |
| − | | + | |
| − | See [http://perpetual-notion.blogspot.com/2008/06/gentoo-on-eee-pc.html this] blog post for further details. If you are lacking in extra space on your flash device, or are concerned about extraneous write-cycles to your flash memory, then you should perform all of the steps on desktop linux machine and then finally copy the resulting squashfs image to the FreeRunner.
| + | |
| − | | + | |
| − | == Openmoko Overlay ==
| + | |
| − | First, emerge layman (you need to build it with svn support, so USE="svn", maybe you should set it just local). Then add the overlay with layman -a openmoko and put source /usr/local/portage/layman/make.conf in your /etc/make.conf. Finally, have a look at /usr/local/portage/layman/make.conf, and add make PORTDIR_OVERLAY look like this: PORTDIR_OVERLAY="/usr/local/portage/layman/openmoko/trunk/openmoko-target"

| − | == Binary package wishlist ==
| + | |
| − | As i'll be adding some packages to ftp above you might want to ask for some package here: [[GentooPackageWishList]]<br>
| + | |
| − | Overlay with moko things and more packages coming soon.
| + | |
| | | | |
| | + | Please note, unless you use distcc, it takes a long time to get a fully working system this way (About 3 days for xorg with fluxbox). |
