[ODE] dJointSetBallAnchor LINK problem

[Paul Carrington]

I'm baffled and hoping someone can help..

I've been playing around with ODE for a few months, it's all working a dream!

I've just started to explore joints. I created a ball joint and attached it to two bodies
and it all compiles and works. I notice that the joints position has been set to the
centre of the first body, "not to worry", I say to myself, whilst reading all about the
dJointSetBallAnchor function. So far so good

Now to my problem

When I use the dJointSetBallAnchor function I get a linker compile error

error LNK2001: unresolved external symbol _dJointSetBallAnchor
fatal error LNK1120: 1 unresolved externals

I have no idea why!!!! The ode-joint.cpp is included and I can even see the function
called dJointSetBallAnchor

please help!!
