==Introduction== |

[[Sugar]] builds relatively reliably as of 2007-12-13 on Gentoo amd64 boxes using sugar-jhbuild, it is extremely likely that it would build on an x86 box as well. |
|||
'''This page has been [http://wiki.sugarlabs.org/go/Community/Distributions/Gentoo moved] to the Sugar Labs wiki.''' |
|||
==Prerequisites== |
|||
You will need to emerge quite a few pieces of software, with some of the packages being ~x86/~amd64 masked or potentially hard-masked (none are as of 2007-12-13 for AMD64). For packages which are ~x86/~amd64 masked you will need to add them to your /etc/portage/packages.keywords file. |
|||
To unmask a hard-masked package, add a line such as the following to your /etc/portage/package.unmask file (note, the following are for example only, they are not needed as of 2007-12-13): |
|||
=dev-libs/libnl-1.0_pre6 |
|||
=net-misc/dhcdbd-1.14-r1 |
|||
To unmask a keyword-masked package, add a line with the full name of the package to your /etc/portage/package.keywords file, which by default adds the appropriate keyword for your architecture (~x86, ~amd64, etc): |
|||
dev-lang/python ~amd64 |
|||
dev-python/setuptools ~amd64 |
|||
net-misc/networkmanager ~amd64 |
|||
dev-libs/libnl ~amd64 |
|||
net-misc/dhcdbd ~amd64 |
|||
dev-python/dbus-python ~amd64 |
|||
Note that you can also use the full format (including comparison operator and version) as specified in the package.unmask file above if you want to prevent frequent updating of packages. |
|||
You will also likely need to specify USE flags for a number of packages. These are added to the /etc/portage/package.use file in a format like so: |
|||
dev-util/subversion -apache2 |
|||
net-dns/avahi dbus python gtk |
|||
dev-python/gnome-python-extras firefox |
|||
x11-base/xorg-server kdrive |
|||
net-wireless/wpa_supplicant -qt4 |
|||
=== Python 2.5 is Required === |
|||
You will need to upgrade your Gentoo installation to Python 2.5, most Gentoo systems as of 2007-12-13 will already be running Python 2.5, but just in case you aren't yet, upgrade and remember to run python-updater! |
|||
=== Emerge the prerequisites === |
|||
Sugar requires a large number of standard Gentoo packages, you will need to emerge all of them in order to build the package: |
|||
emerge -avDt \ |
|||
dev-util/git\ |
|||
cvs subversion\ |
|||
gtk-doc\ |
|||
avahi\ |
|||
expat\ |
|||
gstreamer\ |
|||
xulrunner\ |
|||
pycurl\ |
|||
networkmanager\ |
|||
gnome-python-desktop\ |
|||
gnome-python-extras\ |
|||
dev-python/dbus-python\ |
|||
boost\ |
|||
darcs\ |
|||
fribidi \ |
|||
sqlite \ |
|||
numpy \ |
|||
gst-python \ |
|||
gst-plugins-theora \ |
|||
vte |
|||
You will also likely need to rebuild the x11-base/xorg-server package to build the "nested X servers" module, (particularly the "Xephyr" server which Sugar uses) this is done by specifying "kdrive" USE flag then rebuilding the server: |
|||
emerge -avDt --newuse xorg-server |
|||
Lastly, you will need to have the json-py module installed. There is an [http://projects.liquidx.net/linux/browser/portage.local/dev-python/json-py/json-py-3.4.ebuild ebuild] available which you can use to produce a proper Gentoo package in an overlay locally. Or you can use layman: |
|||
emerge -avDt layman |
|||
layman -a liquidx |
|||
emerge -avDt json-py |
|||
Or you can just unpack the [http://sourceforge.net/project/showfiles.php?group_id=137891&package_id=151451 source package] manually and copy the json.py file to your PYTHONPATH. |
|||
=== Setup System Services === |
|||
You will want to ensure that the required services are started at boot time as well. If you want to run sugar without rebooting you will want to start the services using their /etc/init.d/ scripts as well: |
|||
rc-update add avahi-daemon default |
|||
rc-update add NetworkManager default |
|||
rc-update add dbus default |
|||
rc-update add hald default |
|||
If you do not have these services running when you attempt to start Sugar you will get access exceptions from dbus as your regular user is not allowed to create these system-wide services. |
|||
You will also need to alter you /etc/conf.d/net configuration to specify the use of the NetworkManager compatible dhclient module. This should be the first line in the file: |
|||
modules=("dhclient" "wpa_supplicant") |
|||
If you use the default "dhcpcd" module instead your network will connect, then immediately drop off when NetworkManager takes control of it. |
|||
'''NOTE''' changing your network configuration can easily be messed up, you're a Gentoo user, we're assuming you know how to fix your machine while offline if the network configuration doesn't work! Particularly if you're on a laptop, wpa_supplicant can be a serious pain to configure. |
|||
== Sugar-jhbuild == |
|||
Use of Sugar-jhbuild is detailed on [[Sugar#Build_from_sources|building Sugar from sources]]. To get sugar-jhbuild: |
|||
git-clone git://dev.laptop.org/sugar-jhbuild |
|||
To summarize the build instructions, in order to build the absolute latest version of Sugar: |
|||
cd sugar-jhbuild |
|||
./sugar-jhbuild update |
|||
./sugar-jhbuild build |
|||
If you encounter an error during the installation of python-dbus regarding the types module not being importable, it is safe to ignore the error, the installation script is trying to compile Python modules, which is not necessary under sugar-jhbuild. Upstream is aware of the problem but hasn't fixed it. |
|||
Note that you may need/want to disable building Python in order to prevent conflicts between the jhbuild-based and platform Python. To do this, create/edit the file ~/.olpc.jhbuildrc to add the line: |
|||
skip = ['python'] |
|||
=== Testing Sugar === |
|||
When using [[Sugar_with_sugar-jhbuild|sugar-jhbuild]], you can use: |
|||
./sugar-jhbuild run |
|||
If you want to run Sugar code from the shell/terminal/console: |
|||
./sugar-jhbuild shell |
|||
You can start the sugar shell from this environment with: |
|||
sugar-emulator |
