0.4.0 SDK linker errors

I'm trying to integrate LibOVR into my game engine and am running in to a bunch of linker errors (I'm using VS2013 for a 32-bit application). Performing the normal steps and also using the OculusRoomTiny sample as a guide, I:

- add the paths for both LibOVR\Include and LibOVR\Src to "C++->Additional Include Directories"
- add the path for LibOVR\Lib\Win32\VS2013 to "Linker->Additional Library Directories"
- add "libovrd.lib"/"libovr.lib" for Debug/Release builds to "Linker->Input->Additional Dependencies".

I then go by the documentation and import "OVR_CAPI.h" and then try calling "ovr_Initialize();". The linker errors I get are:

Are there any steps that I am missing?

    Found this thread which solved it:

    viewtopic.php?f=34&t=473

    As I couldn't (nor should have to be) bothered to find out which libraries libovr needs to link against, I just copied all of the dependencies that OculusRoomTiny uses. If libovr requires us to link against additional libraries, this should be mentioned in the documentation as I don't think it should be on the developer to trial-and-error each library in OculusRoomTiny to see if their application compiles.

    Thanks for following up on this.

    I've already brought this up with the team, and we should be updating the documentation soon to reflect this.

    Sorry for the confusion.

    No need to apologise, I understand that this is all still WIP (hence not being called a 1.0 SDK ;)).

    YUP, just want to second this.

    Got my OVR today, went ahead to get a test project up and running and ran into this linker issue -- wasn't sure if I built the right lib, was missing includes or had my paths correct, so spent some time thinking I was an idiot. Led me to conclude I was missing other libs (and confirmed with some searching).

    Not a huge deal, just an annoyance when you're following along the otherwise thorough documentation on integrating the SDK into your app. Would have figured it out on my own, but it was a bit of a hiccup in an otherwise awesome job with the documentation. Just needs something like the following to avoid some initial frustration:

    "Since the SDK depends on other standard libraries (e.g. winmm.lib, kernel32.lib, user32.lib, etc), you'll need to make sure your project links against those as well. The easiest way to make sure you're not missing anything is to simply add the same libs that the TinyRoom project depends on to your project."

    I'm having issues, it should be right now but it isn't working. Spent 2 weeks on this crazy linker issue! Here are my errors:

    My Code is pretty simple... updated from the developer guide, which is obsolete (just getting functions ready for my main app):

    Oculus.h

#include "OVR_Kernel.h"

using namespace OVR;
using namespace std;

// include the Direct3D Library file
//#pragma comment (lib, "d3d11.lib")
// define the screen resolution
#define SCREEN_WIDTH  800
#define SCREEN_HEIGHT 600

// function prototypes
void Initialization(ovrHmd hmd);

void Initialization(ovrHmd hmd)
{
	ovr_Initialize();

	if (hmd)
	{
		// Get more details about the HMD.
		ovrSizei resolution = hmd->Resolution;
	}
}

void Tracking(ovrHmd hmd)
{
	// Do something with the HMD.
	// Start the sensor which provides the Rift’s pose and motion.
	ovrHmd_ConfigureTracking(hmd, ovrTrackingCap_Orientation |
		ovrTrackingCap_MagYawCorrection |
		ovrTrackingCap_Position, 0);
	// Query the HMD for the current tracking state.
	ovrTrackingState ts = ovrHmd_GetTrackingState(hmd, ovr_GetTimeInSeconds());
	if (ts.StatusFlags & (ovrStatus_OrientationTracked | ovrStatus_PositionTracked))
	{
		ovrPosef pose = ts.HeadPose.ThePose;
		float yaw;
		float eyePitch;
		float eyeRoll;
		eyePitch = pose.Orientation.x;
		eyeRoll = pose.Orientation.z;
		yaw = pose.Orientation.y;
		pose.Orientation.w;
	}
}

	ovrHmd_Destroy(hmd);
	ovr_Shutdown();
