OgreBullet Compile Error

Hello all,
I am a beginner in OgreBullet.
I have downloaded OgreBullet_SDK, and when I compiled it, I met an error:

error C2440: 'static_cast' : cannot convert from 'btTypedConstraint *' to 'btRaycastVehicle *'

And the error happened in the area of following code:

btRaycastVehicle *getBulletVehicle()
{
return static_cast <btRaycastVehicle*> (mConstraint);
};

Thank you for your kind help and reply.

Regards

Hello all,
I add something.
I compile OgreBullet_SDK, since I want to get the Libs, for example, OgreBulletCollisions_d.lib, OgreBulletDynamics_d.lib, etc.
because when I set-up applications based on OgreBullet, they need those libs.

Thank you !

Hello all,
I found a previous post on this topic,
viewtopic.php?f=12&t=12314
It seems that the solution is: to grab the OB source from SVN.

But I did not sucessed~

Thank you for your reply.

Hello all,
Anyone help?

what OS, bullet version and ogre version you use?

what OS, bullet version and ogre version you use?

Hi
thank you for your reply.

I am working on windows, Ogre1.65 and Bullet 2.76.

I downloaded OgreBullet_SDK, and installed it.
But When I compiled it, I met errors as described in above postes.


Hoping for your help and hints.

Regards.

Check in Visual Studio or in your IDE if the include files and libraries directories is setted correctly, check the bullet directories (see ogre bullet wiki)...

if everything is correct can you try to compile with ogre 1.7.1

hello
Yes, I correctly set up the libs and headers files. The errors with Ogre 1.65 still exist (errors above!)

I followed your advice and tried Ogre1.71. Unfornately, another error is coming:
UserDefinedObject is not a member of Ogre,

It seems that userdefinedObject is not defined in Ogre1.71. It is true when I open Ogre.h in Ogre1.71 headers files.

In fact, I download OgreBullet SDK from: http://www.ogre3d.org/forums/viewtopic.php?t=29034
I am not sure whether there is newer version of OgreBullet SDK.

I notice that, there are some patches for OgreBullet : http://sourceforge.net/tracker/?group_i ... id=1064241

I download "OgreBullet patches for Ogre1.71 compability", put it my working dir of project OgreBullet_SDK, I failed also.


thank you for your reply.

Do not use the Ogre Bullet SDK it is outdated. See: viewtopic.php?f=12&t=4155 for how to get the newest source.

I have completely same error.

Ogre 1.7.3 VS 2010 SDK( setup env vars )
latest OgreBullet from the SVN
Latest Bullet 2.7.8( which had been sucessfully built and setup env vars )

I've been fighting with this error about two days, tried different combinations of Ogre 1.7.3,1.7.2,1.7.1 + Bullet 2.7.7, 2.7.8 + OgreBullet from SVN.

My linker depencies in Debug

Could someone help me please?

If someone else will face that errors...

It caused by bullet's configuration in cmake, my cmake script chosed options (install libs, install extra libs, anв double precision), don't know which of this options definetly caused errors, but if that options unmarked, all will be ok.
