Xcode Error Message - errno=21 for architecture arm64

July 5, 2019 - 1:09pm #1

Hello folks,

I am trying to compile the Vuforia Core Samples and I am getting the following error message in Xcode. I have attempted to clean the build folder, deleted the Derived Data folder, disabled the Metal Editor Support, but still the problem persists.

ld: can't open output file for writing: /Users/gmead/Library/Developer/Xcode/DerivedData/Unity-iPhone-albzhtibxamjymdddgixlcwzwsws/Build/Products/ReleaseForRunning-iphoneos/vuforia.app/vuforia, errno=21 for architecture arm64

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

The above happens with both of the following configurations...

MacOS 10.14.5, Unity 2018.4.3f1, Vuforia 8.3.8, and Xcode 10.2.1

MacOS 10.14.5, Unity 2019.1.9f1, Vuforia 8.3.8, and Xcode 10.2.1

Any help would be greatly appreciated, thanks in advance.

Glen

Hello,

Based on the provided output the issue seems to be when xcode is compiling, not related to unity or vuforia engine.

Have you tried searching for the error online? there are several findings that might help you, for example like this

Thank you.
