One of the easiest ways to install Sugar is to use sugar-jhbuild.

Sugar-jhbuild will automatically download the latest of Sugar's dependencies as well as Sugar itself directly from their source repositories, rather than relying on source packages that may have become stale. Below are generic instructions on how to use sugar-jhbuild to get up and running with Sugar.

Compatible Platforms

sugar-jhbuild is quite demanding with regard to the packages and setup for the host Linux distribution. As a result there are only a few Linux Distributions which are known to work with it.

The installing Sugar wiki category collects the various articles which detail platform-specific considerations for installing Sugar.

Platform-specific issues are discussed under the platform (distribution) names in the navigation bar to the right. You should read these notes before beginning your Sugar installation.

Checkout sugar-jhbuild

In a suitable directory, execute

git-clone git://dev.laptop.org/sugar-jhbuild

Build sugar base system and its dependencies

Change directory and start the build.

cd sugar-jhbuild
git-pull
./sugar-jhbuild update
./sugar-jhbuild build

For the base packages , you may be able to use the binary packages from your GNU distribution instead of building them from scratch. Check the Installing or Linux categories for specific distro info.

You may have some issues with penguintv on ubuntu, just interrupt the pull with a CTRL+C, open a shell, repeat the command manually, and accept the certificate permanently.

One other fix that I had to do was to export GTK2_RC_FILES=~/src/olpc/sugar-jhbuild/build/share/themes/sugar/gtk-2.0/gtkrc and also symlink build/share/icons/sugar to build/share/icons/hicolor. These two steps may not be necessary, but they made things work on my Ubuntu installation as of March 31, 2008. Blaketh 03:08, 31 March 2008 (EDT)

Run Sugar

This command launches the Sugar emulator:

./sugar-jhbuild run

To exit the emulator, press Alt-Q.

Running multiple instances

To run multiple instances of sugar you can start it in the following way:

SUGAR_PROFILE=2 ./sugar-jhbuild run

Run an individual activity

Within the sugar shell (./sugar-jhbuild shell), this command launches an individual activity for testing (from the mailing list):

sugar-activity [bundle name]

Configure the mode and resolution of Sugar

You can make Sugar run in a window as well as specify a resolution. Within the /sugar-jhbuild/build/share/sugar/shell directory, backup, then edit the python program file emulator.py:

cp /sugar-jhbuild/build/share/sugar/shell/emulator.py /sugar-jhbuild/build/share/sugar/shell/emulator.py.backup
nano build/share/sugar/shell/emulator.py

Find this piece of code:

    cmd = [ 'Xephyr' ]
    cmd.append(':%d' % display)
    cmd.append('-ac')

     if gtk.gdk.screen_width() < 1200 or gtk.gdk.screen_height() < 900:
         cmd.append('-fullscreen')
     else:
         cmd.append('-screen')
         cmd.append('%dx%d' % (1200, 900))

Comment out the if and else instructions, and specify the screen resolution and mode you want (it's important to delete 4 spaces before the "cmd.append" lines):

    cmd = [ 'Xephyr' ]
    cmd.append(':%d' % display)
    cmd.append('-ac')

#    if gtk.gdk.screen_width() < 1200 or gtk.gdk.screen_height() < 900:
#        cmd.append('-fullscreen')
#    else:
    cmd.append('-screen')
    cmd.append('%dx%d' % (800, 600))

Sugar will now run on a 800x600 window. This file may be replaced next time you update sugar-jhbuild, and you'll have to do this again. Also note that 800x600 is not an optimal resolution for the window, because the activity circle will be vertically off center. 1024x768 is a more useable resolution.

Other commands

JHBuild has several other commands that can be useful for development. You can get an overview with:

./sugar-jhbuild --help-commands

A useful sequence of commands for building Sugar, from the Sugar mailing list:

./sugar-jhbuild update
./sugar-jhbuild build
./sugar-jhbuild run

From Within Sugar

Once you have Sugar running, here are some useful commands:

  • Alt+F makes the frame appear and disappear
  • Alt+C quits an activity
  • Alt+0 brings up the developer's console
  • Alt+Q quits Sugar
  • Alt+N switches applications within sugar (like alt-tab on the device)

Customize

To customize the build create a configuration file, named .olpc.jhbuildrc, in your home directory.

Write access to the repositories

If you have write access to the repositories you can add this (if your login name happens to be marco):

repos['gnome.org'] = ':ext:marco@cvs.gnome.org:/cvs/gnome'
repos['mozilla.org'] = ':ext:marco%gnome.org@cvs.mozilla.org:/cvsroot'
repos['dev.laptop.org'] = 'git+ssh://marco@dev.laptop.org/git/'
repos['dev.laptop.org/projects'] = 'git+ssh://marco@dev.laptop.org/git/projects/'
