Quick Start - LiveCD

For many, the LiveCD is the easiest way to try Sugar. It's easy to do, but your work is lost when you reboot.

Quick Start - Emulation

Emulation is the other way to try Sugar. It can be harder to set up,, but work is preserved.

Sound in TamTam may not be working at the moment. MitchellNCharity 13:16, 5 June 2007 (EDT)

Overview

One way to run oplc software is using an emulator on your pc. See Getting started programming for other options.

Note Category:Emulation and Help and tips.

For play, you can use LiveCd or Quick Start.

For development, you can use LiveCd, or qemu (as in quick start, but with a different image), or perhaps one of the Developer Images other than the LiveCd. An alternate approach is to attempt installing sugar. See Getting started programming for a comparison.

A common development approach is to use QEMU with kqemu acceleration. See Quick Start for the basics. Though for development, we will use a different .img, one with a few extra utility programs. See OS images, including latest stable build.

Instead of qemu, you can run VMware, and there are additional options on a Mac.

Please report your experiences in User Feedback on Images. There is a Virtualization Common Room.

There are limitations with XO disk images.

Developing software

Developing on emulation is one alternative for developing software.

After looking at /Quick Start, see /Help_and_tips#Development for how-to's. It should be straightforward on linux.

Comparison of alternatives

An OLPC laptop is custom hardware, running a stripped-down Red Hat linux, running Sugar. But what if you don't have a real olpc laptop? There are a several options.

option	updated	sound?	camera?	library?	etoys?	R/W?	development software?	net?	comments
LiveCd	April	yes(boot) yes?(qemu)	yes?(boot) no(qemu)	no	yes	no	toolchain, Gnome	yes?	Alternative Quick Start. Good for new developers. Can both be booted from, and used in qemu. Problems: A.
XO disk images:
LATEST-STABLE-BUILD http://olpc.download.redhat.com/olpc/streams/development/LATEST-STABLE-BUILD/
...development-ext3.img	~monthly	yes/B	no	yes	yes	yes	no	after config	Quick Start for getting a look at Sugar.

OTHER
FC6+Sugar	April	yes?	?	?	no	yes	Full Fedora Softare Dev.	yes	6GB (April version: no etoys)
Installing Sugar	continuous	yes	yes?	yes?	yes	yes	your own	yes	Quite hard to do.

Key:

library: A library of sample content is included (english version). Ie, pretty text to web browse without having to get network.

R/W (writable): With an .img, you can save things between sessions. With a .iso, your environment is the same each time you start.

development software: are development tools included?

Net (network): does the network "just work" or "manual" steps are required?

Problems:

A: LiveCd (April) on fc6 x86_64, kernel panics under kqemu. A squashfs problem.

B: Tam Tam is silent (though EToys makes noise). Cause unknown.

Notes:

• re "does sugar-jhbuild support camera/mic?": "yes, if the camera uses v4l2 and 640x480, I'd suspect so." Can someone confirm this? (#olpc, now) MitchellNCharity 00:16, 2 June 2007 (EDT)

Doables:

• Remove LiveCd's "?" above.
• Find out what's going on with Tam Tam sound. It would be nice for the xo disk images to all be sound-yes.
• Add a microphone column? Reconsolidate sound/camera/mic into a H/W column?
