That's strange, the file should be included in the UnityPackage regardless of PC or Mac. I'm glad reimporting Vuforia resolved your issue!

Thanks,

Reimporting the Unity Vurforia package added the missing files and fixed my Linker errors. Thanks for working through this with me.

For what it's worth, I started this project on PC, got the latest version of Vurforia for Unity, imported it, then via version control moved the project over to OSX. From there was where I was building to iOS. I'm not sure why the files I was missing wouldn't have been imported from the PC version of the Vurofia package, but I definitely didn't explicitly exclude them.

That should be getting linked and included through Unity. Navigate to Assets/Plugins/iOS/ and you should find it there. Select it and look at it in the Inspector panel. Make sure that the section for "Select platforms for plugin" has iOS checked.

Attached is a screenshot of the file selected with the Inspector having the correct box checked.

If you aren't seeing this file, could you try re-downloading the Vuforia SDK and re-importing it into your project.

Thanks,

It looks like libVuforia.a is missing. Does that get included and linked through the Unity plugin, or do I need to set that up elsewhere?

I've uploaded an image of the libraries and frameworks that are being included in the XCode project that is built from Unity. Are you missing anything seen here?

@Strasza, does this information help? Can you tell me what libraries need to be linked and where, since the auto setup of XCode from Unity doesn't seem to be linking everything?

My Xcode is 8.3.3.

With a fresh version of the sample project in Unity 5.6 with Vuforia 6.2.10 I am able to build to iOS without any issues. I am on Sierra 10.12 as well. What version of XCode are you on?

Thanks,

I tried solutions from that thread (3 years old), but they didn't fix the Linker errors. This should be a pretty easy issue to reproduce since I'm building from all latest versions on latest macOS (Sierra 10.12) with a clean project. It looks like there is just a missing library link, but I'm not sure what or where. The scripts the error log is complaining about are: VuforiaRenderDelegate.o, VuforiaNativeRendererController.o, and (mostly) Bulk_Vuforia.UnityExtensions.iOS_0.o.

I have not personally run into this issue before, but here is an old thread that encountered it in the past. It looks like it might contain the solution you're looking for.

@Strasza, any ideas?

I just installed Unity 5.6 and building in Xcode has the same errors.

Hello jlink5,

Could you try this with Unity 5.6 instead? Unity 2017.1 is not an officially support version of Vuforia 6.2.10.

Thanks,
