Correct way to use CNewton?

[MeltingPlastic]

Hi all, I've been trying to get the CNewtonTutorial code working by linking against the Dll's.
I originally was using the plain c interface (and that worked fine). but now I cant get the CNewton interface to work...

I created a fresh project in Visual Studio 2013 and copied the CNewtonTutorial code to my main cpp file and set up the project to look in:

packages\projects\visualStudio_2012_dll\Win32\dNewton\release,
packages\projects\visualStudio_2012_dll\Win32\dJointLibrary\release,
coreLibrary_300\projects\windows\project_vs2012_dll\Win32\newton\releaseDll

for the libraries newton.lib, dNewton.lib, and dJointLibrary.lib.

But at compile time I keep getting these errors - any clue as to what I could be doing wrong?

Thanks in advance!

The CNetwon Class is an all in one dll, the only library you need to link is CNewton.lib

To make it easier I added and new visual studio 2010 solution ../newton-dynamics\applications\tutorialsSDK300\CNewtonTutorials\newtonTutorialsDll.sln
this links to the CNewton DLL, and I think it is simple enough that you can figure out how to use it.

if you want to use the DLL set of library you can do it in tow ways,
1- open and build the solution, ..\newton-dynamics\packages\projects\visualStudio_2010_dll/build.sln
and you can either use environment variables, relative path, or copy the file to your project.
2-add the libraries projects as sub-project dependencies of your solution, and set the relative path.


sync to SVN so that you get the example using CNewton.dll

Thanks Julio, It makes sense that the only lib needed is CNewton.lib - works great now!
