Linker errors with 'Creating a Project from Scratch'

[InsertWittyName]

Hi guys,

I've been trying to get Bullet working using the following tutorial: http://www.bulletphysics.org/mediawiki- ... om_scratch

- I downloaded bullet-2.77.zip, and extracted it to c:\develop
- Using CMake 2.83, I built Bullet in c:/develop/tutorial/BulletBuild, using Visual Studio 10 as the compiler
- I create a new project in Visual Studio 2010, a Win32 Console Application, called BulletTestApp
- I add the BulletCollision.vcxproj, BulletDynamics.vcxproj and LinearMath.vcxproj from C:/develop/tutorial/BulletBuild/src/... to the project
- I set the project dependencies for the BulletTestApp, ticking BulletCollision, BulletDynamics and LinearMath
- I set the Additional Include Directories for BulletTestApp to c:\develop\bullet-2.77\src (for all configurations)

The program code is:

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;
}

Which produces:

- As suggested in the tutorial, I then set Link Library Dependencies to 'Yes', for all configurations, for BulletCollision, BulletDynamics and LinearMath, but it produces the same 14 unresolved externals.

I've searched for threads regarding unresolved symbols and bullet, but none of them had answers which solved the problem. Can anyone suggest how I might go about fixing this?

Any help would be appreciated

Fixed my own problem

In BulletTestApp's properties, I added new references to BulletCollision, BulletDynamics, and LinearMath.

Hello,

I think that I am having the same problem as you did. Could you please tell me how you added references to the libraries. Right now, I BulletTestApp Properties -> VC++ Directories -> Library Directories has the path to the library that has all the compiled library files in it. Is there anything else you did?

Oh never mind, I solved my issue. After performing all the steps mentioned previously in this thread, I did the following:

1) I use MSVS 2010 x64, so I had cMake build the libraries using the MSVS 2010 64 bit generator. But, while making the BulletTestApp project, I chose the target platform as Win32. I changed the target platform to x64 for BulletTestApp.

2) I went to BulletTestApp (Right Click on the project name) -> Add -> Existing Item. Then I added BulletCollision.lib, BulletDynamicslib and LinearMath.lib to the project.
