cmake fails

[Anti-Distinctlyminty]

Hi all,
Sorry if this has already been covered. I did look around for quite a while but didn't find anything.
I've followed the instructions here:
http://www.bulletphysics.org/mediawiki- ... om_scratch

And immediately ended up with this:

cmake.jpg

I'm assuming that Bullet depends upon OpenCL and DirectX? If so is there a certain version I should be downloading to use? Also, there seems to be a warning about OpenGL.
This is all very odd as all I've done is follow the instructions to the letter.

Any help would be very much appreciated.

Ok, even though my cmake results didn't seem to tally with the ones shown in the instructions I went ahead anyway and carried on with the example. With this code:

Code: Select all

#include "stdafx.h"
#include "btBulletDynamicsCommon.h"


int _tmain(int argc, _TCHAR* argv[])
{
	btBoxShape* box = new btBoxShape(btVector3(1,1,1));
	return 0;
}

I get a bunch of linker errors. The imported projects (BulletCollusion, BulletDynamics & LinearMath) all compile ok. I just can't use them because of the linker errors:

Had to set
Linker>General>Additional Library Directories = C:\develop\tutorial\BulletBuild\lib\Debug;
and
Linker>General>Input = BulletCollision.lib;BulletDynamics.lib;LinearMath.lib + whatever was already there

Seems to compile now.
Not sure what I did differently from the instructions though...
