Sample fails on iOS

November 7, 2013 - 3:02am #1

Hi,

I am running the Image Targets Unity Extension sample on an iPad, and when reaching scene 4 (the scene that actually have the AR stuff), it shows a dialog saying "Failed to initialize QCAR" and closes.

The log says:

<pre>

trackerManagerInitTracker
 
Error: Image Tracker could not be initialized.
 
Could not initialize the tracker.
 
UnityEngine.Debug:Internal_Log(Int32, String, Object)
 
UnityEngine.Debug:LogError(Object)
 
TrackerManagerImpl:InitTracker(Type) (at /Users/ilang/test/Assets/Qualcomm Augmented Reality/Scripts/Internal/TrackerManagerImpl.cs:67)
 
DataSetLoadBehaviour:Start() (at /Users/ilang/test/Assets/Qualcomm Augmented Reality/Scripts/DataSetLoadBehaviour.cs:52)
 
 
 
(Filename: /Users/ilang/test/Assets/Qualcomm Augmented Reality/Scripts/Internal/TrackerManagerImpl.cs Line: 67)
</pre>
 
As far as I can tell, I followed all the instructions to the letter.
 
I am using:
Unity Pro (with iOS Pro) - 4.2.2f1
and the latest xCode - 5.0.1.
 
Can you please assist me?
 
Thank you very much,

I meant just run it through XCode to see what the log says.  You cannot debug / look into the library functions.

How can I debug that code?

It's in the CPP code of the .a file...

I don't know why it is not working.

One thing you could try is just building it with scene 4 and then debugging through XCode to see what the log says.  Maybe it might display why the tracker has failed to initialise?

  • This is the sample out of the box, no changes - just a new project and the unitypackage import.
  • Latest - 2.6.7
  • iPad 3rd Gen, software version 6.1.3

I don't have any other iOS devices, so I haven't tried running on other devices.

I haven't tried running any other samples yet (I will), but it all started when another project I'm working on failed in the same way after running fine on Android.

I understand that this means something is fundamentally wrong. Is there an important step I'm missing? Is this some incompatability with newer versions?

Thank you very much,

Hi

Just a few questions to try and narrow down:

  • Is this the Image Targets sample out of the box? or have there been any changes?
  • Which version of Vuforia is it?
  • Which iPad version is it?
  • Which iOS version is it?

 

Also, have you tried running this on another device, or tried running any of the other samples?

Basically this should run out-of-the-box, otherwise there is something fundamentally wrong.
