Hey everyone. I'm new to Bullet and I'm trying to run the Hello world code found in the getting started section. I'm getting the following errors using Visual Studio 2017. I followed the installation guide, so not sure why it's not working. Thanks for any input

You need to link your project with BulletCollision, BulletDynamics and LinearMath libraries.
Check Properties>Linker>Input if you have them in Additional dependencies.

Not seeing them. But when I try to add them it's telling me it cannot open file. I've tried Bullet3Collision_Debug.lib, Bullet3Collision.lib and BulletCollision.lib

I personally have in debug:

LinearMath_Debug.lib
BulletCollision_Debug.lib
BulletDynamics_Debug.lib

Edit: don't forget to set them with their path

OK, yeah, I have those in my debug folder, and added them to the additional dependencies, but still getting the error.

Do I have to have the linker point to the debug folder?

EDIT: Figured it out. Had to enter the entire path. Thanks!

You have no path set for them, so Visual is searching at the root of the project.
Add absolute path of the libraries
