You need to add the Security framework, and then all should be fine :)

Well, I noticed something stupid on my part. I was doing the development on my pc wich has the android plug-in and when I opened it on the mac it still had the android version of the plug-in. So I fixed that and it got rid of a lot of errors, but not all of them. I'm down to only 17 errors:

ld: symbol(s) not found for architecture armv7

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any help would be appreciated. By the way, I'm still using Unity 3.5.6.

I was wondering if you found how to fix this as I am also experiencing 60 erros when try to build the xcode project.

The erros look like this:

I have set the Architectures to armv6 armv7 and BUild Active Architecture Only to No. The project file does not have any spaces in its name.

Have you checked you have no spaces in your filenames or directory names at all?

What happens when you create a sample from scratch using ImageTargets?

Here is the latest info I can provide to best help you solve issue:

Unity 4

- I have pro version of both Unity and the iOS extension

Vuforia ios 1.5.10 unity extension

XCode 4.5.2

- Architectures and Valid Architectures all set to armv7 under Build Settings (Resolved, Unity-Iphone, Unity-Iphone). However, iOS Default is      grayed out and I cannot change. It is set to Standard (armv7, armv7s)

 - Keep receiving "Apple Mach-O Linker Errors" with regard to Vuforia features

(there are 62 errors total... Ive only provided some of them)

It could be because you are using Unity 4 which is not yet supported by Vuforia

Unity 4 Update

..though it is hard to say as you have not posted any details of what these errors are ;)

Using armv7 only in XCode 4.5.2 > Build Settings > Architectures and still have Apple Mach-O Linker Errors.

Again, here is workflow:

Vuforia 1.5.9

Unity 4 beta

XCode 4.5.2 (compiling for iPhone 3GS)

I can compile for Android with no problem.

hi tgotzsche,

Many thanks for this.

Another developer did report this earlier and I did respond here.

found workaround

http://stackoverflow.com/questions/12534334/linker-command-failed-with-exit-code-1-xcode4-5

I also have this problem since upgrading to iOS6 and XCode 4.5

ld: file is universal (2 slices) but does not contain a(n) armv7s slice: ../../build/lib/arm/libQCAR.a for architecture armv7s

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Phone: 4S running iOS

XCode: 4.5

SDK  : 1.5.9

I cant compile any of the samples or my own projects.....

when i mean is that i update the vuforia package with that, i will download the new xcode, but made some others tests and a clean project works greate, so i conclude that something happen with my project.

But i will tried update the xcode.

Hi Darkmax,

 i update the unity package with the new version,

..you mean you updated the libQCAR.a in the Unity project - as we did not release any new unity package

You seem to be using XCode 4.4.1 ?

My understanding from iOS6 was that it used 4.5.3 (preview) which is required to build iOS6.

If you are not using this could you please try with this?

The other thing I have seen sometimes is problems with spaces in file names - make sure you have none of these in your build directory path.

thanks
