Unity 2014.4 LTS, iOS and Vuforia 8.3.8 compile problem

By SidAdmin on Mon, 09/14/2020 - 13:51

Hi,

I'm using Unity 2018.4 LTS (26f1) in combination with Vuforia 8.3.8. Everything works fine as expected within the Android build.

 

Unfortunately, when compiling the project generated by Unity with xCode (10.2), I get an error:

ld: '[...]/PAE2020/Libraries/Plugins/iOS/libVuforia.a(libVuforia.a-arm64-master.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

 

When I turn off the bitcode (Build settings "Enable Bitcode" set to "no"), I get the error that :

ld: 4 duplicate symbols for architecture arm64

 

What can I do to make this work on iOS?

 

BTW: The minimum iOS version is 11.

 

Thanks for your help.
