thanks for this, I'll have a look. I migth have investigation to reach
that  low size.
On my system just Orocos is biggest than your dependencies+orocos package.


Nothing really new here, just an automated way of compiling orocos (like

Do you mean you uncompress them to RAM on boot ? or is it just the delivery
that is uncompress on your target  ? (The question behind this is what is
the required size on board to run Orocos).
