We'd like to use a shared library written in c++ under Squeak (actually
it is a library called ODE to manage collisions, joints,... between
physical objects; this work will be used to simulate the atoms of the MAAM
project http://www.univ-ubs.fr/valoria/duhaut/maam/) and we are using the
FFI plugin.
However, we need to use external c structures. We tried to make subclasses
of ExternalStructure as in X11 exemples provided by FFI but we didn't
manage to do it. Can someone help us and give us the correct syntax ?
Thanks.
