Activities/Memorize/Sensores

2011-04-01T16:47:48Z

Ebordon:

'''Memorize con Sensores''' es un proyecto de la actividad Memorize, que tiene posibilidad de incluir sensores.

Por ejemplo, un docente puede crear un mapa físico (por ejemplo en papel) y añadirle resistencias electronicas. Al crear una tarjeta se puede asociar tanto a otra tarjeta como a una resistencia electrónica en el mapa.

Dextrose/Building

2010-09-20T12:05:52Z

Ebordon: /* Initial setup */

== Build system ==

Dextrose uses [http://wiki.laptop.org/go/OS_Builder olpc-os-builder], a tool create by OLPC to build official and customized system images. The Dextrose git repository contains, olpc-os-builder, local customizations specific to Dextrose, and fixes and enhancements waiting to be pushed upstream.

== Build host requirements ==

The Dextrose build system runs on '''Fedora 11 i386''' through '''Fedora 13 x86_64'''. The host system runs '''shouldn't''' matter, because the build runs in a chroot environment. olpc-os-builder does not yet run on Ubuntu due to a missing dependency.

The initial build requires about '''700MB''' of rpm packages and Sugar activity bundles. The packages and bundles are cached for futures builds.

== Initial setup ==

* Checkout Dextrose build system

git clone git://git.sugarlabs.org/dextrose/mainline.git dextrose

* Install dependencies

yum upgrade
yum install libtomcrypt-devel bitfrost make gcc mtd-utils python-imgcreate zip unzip zlib-devel

* Compile build helper programs

make

* Generate initial sequence number for the builds

echo 42 >buildnr-dx

== Creating a build ==

* Run the Build

time sudo ./osbuilder.py examples/dextrose2-xo1.ini

The initial build may take several hours depending on available bandwith. Subsequent builds will take about 15-20 minutes

Upon completion the new image is available at <tt>build/output</tt>.

Because several build tools, olpc-os-builder, imgcreate and yum, are nested, error output could be misleading or obscure. Before digging into code, you please ask on IRC in case someone has already seen the same problem.

== Publishing the images ==

Please do not publish signed builds unless they implement the [http://wiki.laptop.org/go/Antitheft_HowTo OLPC anti-theft system].

== Customizing your build ==

olpc-os-builder is documented at
[http://git.sugarlabs.org/projects/dextrose/repos/mainline/trees/master/doc/README README]
in the olpc-os-builder tree. The modules are documented in <tt>README</tt> files in the
[http://git.sugarlabs.org/projects/dextrose/repos/mainline/trees/master/modules modules] directory.

=== Upstream Code ===

Dextrose is based on upstream olpc code located at dev.laptop.org.

git remote add olpc git://dev.laptop.org/projects/olpc-os-builder
git fetch olpc
git log olpc/master

=== Customizing the core RPMs ===

* Go to the <tt>rpms/PACKAGENAME</tt> in the dextrose tree

* Edit the spec file. Typically this involves adding a new patch, which is done by adding a <tt>PatchNN:</tt> tag and a corresponding <tt>%patchNN</tt> rule in <tt>%setup</tt>. Some of the intricacies of RPM spec files are unveiled in the [http://fedoraproject.org/wiki/Packaging/Guidelines Fedora Packaging Guidelines].

* Increase the release number after each change.

=== building the Custom RPM ===

make i586

=== Uploading the Custom RPM ===

* Upload rpm to a yum repository and add it to the ini file used by the OLPC OS builder.

* To automate this step, we have a rule <tt>make uploadrpm</tt> which points at the Dextrose repository. Edit <tt>rpms/common/Makefile.common</tt> or <tt>rpms/common/uploadrpm</tt> to retarget this rule to your repository.

=== Building custom kernels ===

$ git clone http://dev.laptop.org/git/olpc-2.6/
$ cd olpc-2.6
$ setarch i386 make ARCH=i386 xo_1-kernel-rpm

* Interaction with the Sugar and OLPC community to solve issues and minimize our divergence from the official builds.
