[ODE] using a different collision library

[Gregor Jochmann]

Hi,

My project group is developing a collision detection engine (see 
http://d-collide.ematia.de). We are currently 
trying to use it with ODE, instead of the built-in collision code from ODE. 
Having read the instructions at 
http://opende.sourceforge.net/wiki/index.php/Manual_%28Collision_Detection%29#Using_a_Different_Collision_Library,  
I wrote a file that looks like this

#include <ode/ode.h>

typedef dcollide::Proxy* dGeomID; 

extern "C" {
void dGeomMoved (dGeomID movedGeom) { //.... }

dGeomID dGeomGetBodyNext (dGeomID geom) { //.... }

void dGeomSetBody (dGeomID geom, dBodyID body) { //... }
}

But, of course, this produces some compiler errors. The dGeomID type has 
already been declared in ode_common.h, and the function symbols are also 
already existent in the ODE library.

Here is my question: Is it possible to use our own collision library without 
having to modify the ODE source? Or do we need to distribute a modified 
version of ODE with our project?
