Unity Sample Projects and Xcode 4.2

October 17, 2011 - 6:01am #9

Hi,

Has anyone had any experience using the sample projects with Xcode 4.2 exported from Unity?

Once I build from Unity they either fail to load, or come up flooded with errors.

I'm presently trying to get used to the framework and feel my way around things, but am not having much luck with the sample projects =/

I get the following error in Xcode:

Use of undeclared identifier 'mono_dl_register_symbol'

Are you trying to run the app in the iOS simulator? QCAR does not support this, you must run the app on a device.

If that's not it, what version of Unity are you using? What version of iOS are you targeting?

Hey Kim,

I'm building the app to an actual iPhone, not the simulator.

I'm using the latest version of Unity Pro and IOS Pro and my iPhone is running iOS 5.

From Unity I target the latest SDK and IOS Version 4.3 (That's the latest available..)

Yes, I had similar issues XCode 4.2/iOS5 latest version of Unity two weeks ago (not the current one released this week) . Android port worked, but iOS ended up with lots of errors

I'm having trouble with Unity Pro 3.4.2 and Xcode 4.2 not being able to build any projects that use Qualcomm AR. After my own project failed with the new version of Xcode, I tried to build the ImageTarget sample project ad I get the same errors.

Semantic Issue
use of undeclared identifier 'mono_dl_register_symbol'

*** found part of the solution!
In Xcode, be sure that you have Unity-iPhone selected and not Unity-iPhone-Simulator for your scheme. Hopefully this will save someone else hours

Edit: All fixed! Latest update seems to be running superbly.

Hey guys I know this seems to have been fixed

I myself am using Unity 3.4.2 latest xcode and the unity beta extension of qcar 1-5-3. I follow the tutorial and am trying to get a simple box to appear over the image target, but can't even seem to do that.

Wondering if anyone with the same configuration has gotten a project up and running? Maybe someone can provide a very simple Unity project that works?

Try one of the sample projects that comes with the installer. Create a new Unity project and import the unity package (e.g. qcar-unity-imagetargets-ios-1-5-3-beta1). Does that work any better?

When you build a project yourself using the 1.5 extension, be sure to follow the guide in the new 1.5 documentation, available here.

Make sure you follow step 3.1.2.5 - Adding Data Set Load to Camera.
