This infrastructure is just a collection of shell functions that allow to ease the development of recipes ( here is the orocos recipe  http://gitorious.org/bif/bif/blobs/master/framework/packages/orocos-rtt/orocos-rtt.sh ).

I patched buildroot to support the required packages (boost, omniorb, orocos-log4cpp, orocos-rtt, orocos-ocl, etc.). You can find the patched version in the "2011.05-sm" branch available on my github account (https://github.com/phamelin/buildroot/tree/2011.05-sm). You will have to modify the scripts since the source packages were retrieved from a private server. As I remember, the whole operating system including Orocos was fitting on a 32 Mb SD card.


I saw this :
 "   --embedded          Disable Scripting, Exceptions and reduce the
type system."
in your orocos-rtt configure
(https://github.com/phamelin/orocos-rtt/blob/master/configure)

Is this one of the key to reduce the size of the libs ?
