Linking Error on OSX

Yeah, compare that command to the earlier one you posted. You're missing all the framework linkage calls:

 -F/Library/Frameworks ... -framework Carbon -framework QuartzCore -framework CoreVideo  -framework ApplicationServices

You're missing all the core OS libraries. Both projects have an entry that I assume provides a list of object files created by the project...

-filelist /OculusSDK/LibOVR/Lib/MacOS/Debug/MinimalOculus.build/Debug/MinimalOculus.build/Objects-normal/x86_64/MinimalOculus.LinkFileList

-filelist /Users/hesh/Library/Developer/Xcode/DerivedData/IbexMac-csekgxtfsfhfishdfaqcsplitscj/Build/Intermediates/IbexMac.build/Debug/IbexMacRelease.build/Objects-normal/x86_64/IbexMac.LinkFileList

But your earlier linking command had a ton more in it. Sorry I can't be more detailed as to what might be going wrong, I haven't done any Mac development for a while. You might want to consider trying to use command line tools like make which, while less easy to work with, provide much more visibility and control over exactly what's going on. Even going through the experience of debugging a makefile once will probably give you a lot better handle on how to interpret and deal with compile and linking errors when you get them in higher level tools.

Thanks a bunch for trying to help me!
How do I know witch frameworks I need? I was following this tutorial, though it's intended for Windows and Visual Studio. Can you, or some one else, "translate" it to be used with Xcode instead?

I don't have enough experience to help you with XCode settings or what libraries are appropriate to link against on OSX. All I can suggest is looking for tutorials on writing OSX applications, and or starting from the "LibOVR_With_Samples.xcodeproj" XCode project in the SDK and try to modify some of the existing samples.

A recent change to the OSX compile environment was 64 bit compilation by default.
You can check what an object file is with 'file' command.
There is a bash file script that you can change to get back to default 32bit, but I will
not try to retrieve it here. Go google it up or use explicit 32-bit compilation.

I would hazard a guess that it could cause your problem as it cause a lot of hassles for me
in the past.

I'm trying to use the "LibVOR_With_Samples" project to be sure that I get all the necessary libraries, frameworks and heather-files.

But when compiling this code:

#include "OVR.h"

OVR::SensorFusion        FusionResult;

int main(int argc, const char * argv[]){

    return 0;
}

I get this error:

I have been reading away on the net for a couple of weeks now, but I can't find any answers . . .
I can compile the Oculus World Demo without any trouble.

Your link command is missing the OVR SDK library itself.

You presumably need a -lSomething where 'Something' is the name of the library created on OS X. Look at the link commands that are executed when you build the demos.
