[Opensim-dev] DllNotFoundException: lib64/libode-x86_64

[Zadark Portal]

An alternative would be to compile ODE libraries locally.

git clone git://opensimulator.org/git/opensim-libs       .. folder
trunk/unmanaged holds the sources for the physics libraries. Recent updates
appear to be for 'OpenDynamicsEngine-0.13.1mod' so I assume this to be the
version used with Opensim.

Not used the ode myself but I have successfully tinkered with the bulletsim
libraries.
