Standalone C++ program to connect to Oculus linking error

[souvik]

Hi,

I'm trying to write a ridiculously simple C++ program that I want to build on command line or with a Makefile that can connect to my Oculus Rift DK2, and eventually give me the orientation of my head (the 3 Euler angles, say). For now I'm just trying to connect to the HMD, and failing to link to the correct libraries. I'm on a Mac (I know, the developers' veto etc), SDK version 0.5.0.1 that I downloaded several months ago (before they pulled it and the runtime). And this is my silly program:

#include <iostream>
#include "/Users/souvik/CMSRift/OculusSDK/LibOVR/Include/OVR_CAPI.h"

int main()
{
  ovr_Initialize();
  int nHMD=ovrHmd_Detect();
  std::cout<<"nHMD = "<<nHMD<<std::endl;
  return 0;
}

I try to build it using:

c++ Oculus.cc -L ../OculusSDK/LibOVR/Obj/Mac/Release/LibOVR.build/Objects-normal/x86_64/

and get the following linker error:

Undefined symbols for architecture x86_64:
  "_ovrHmd_Detect", referenced from:
      _main in Oculus-386453.o
  "_ovr_Initialize", referenced from:
      _main in Oculus-386453.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

So, where is the equivalent of the libovr.lib or whatever library it is that I need to link against?

Thanks!

PS: Where am I going with this? I'm trying to make an event display for the CMS experiment at the LHC, and I have to interface it with the standard programs used in high energy physics for this purpose. Hence my ground-up effort to understand the Rift.
