Hello,
may anybody help me with this bug?

it happens while building with DEMO I am getting this error
/usr/bin/ld: libBtOgre.a(BtOgre.cpp.o): in function BtOgre::DynamicsWorld::addRigidBody(float, Ogre::Entity const*, BtOgre::ColliderType, BtOgre::CollisionListener*)': BtOgre.cpp:(.text+0xb30): undefined reference to btRigidBody::btRigidBody(float, btMotionState*, btCollisionShape*, btVector3 const&)'

If there is no lines to draw (in my case, no bodies in bullet world), DebugDrawer::update throws exception with message:

what(): RuntimeAssertionException: mCurrentSection failed. You cannot call end() until after you call begin() in end at /build/ogre/src/ogre-13.1.1/OgreMain/src/OgreManualObject.cpp (line 324)

My solution: add a flag to mark if there were any line drawing:

bool mBegan{false};

and

void update()
{
	mWorld->debugDrawWorld();
	if (mBegan)
        {
            mLines.end();
            mBegan = false;
        }
}

and

void DebugDrawer::drawLine(const btVector3& from,const btVector3& to,const btVector3& color)
{
        mBegan = true;

Hi guys,
does anybody know why I have this https://youtu.be/VKSiKcNKxwg slightest lag between a hull and wheels of a car?
I use Ogre 13.3 and the latest version of BtOgre. A car is built of 3 relative hierarchic SceneNode objects. Wheels are connected at the toppest SceneNode. The lowest SceneNode contains RaycastVehicle object.
