iOS - SDK 8.4 - Build problem

We are really excited with the new version 2.4 version of wikitude SDK. 


However, since it has been released, we got some problems in building our app on iOS. We got errors mentioning armv7.


This is for instance the error when trying to build the cordova-sample-app project :

 

ld: warning: Could not find auto-linked framework 'WikitudeSDK'
Undefined symbols for architecture armv7:

Thanks,

Hi Amaury,

We removed armv7/armv7s support in our latest update (http://www.wikitude.com/external/doc/documentation/latest/iosnative/changelog.html#release-notes-wikitude-sdk, https://www.wikitude.com/blog-2019-sdk-clean-up/). It might have not been that clear as we not explicitly mention removal of those architectures but only the minimum supported hardware generation, sorry about that.

When we build our Cordova example app, we call `cordova build` like the following: `'cordova build ios --device --developmentTeam=********** --buildFlag="ONLY_ACTIVE_ARCH=NO" --buildFlag="ARCHS=ARCHS_STANDARD_64_BIT"'`. Alternatively you can change the generated Xcode project and set ARCHS to ARCHS_STANDARD_64_BIT (See attached screenshot).


Best regards,

Andreas Schacherbauer

Hi Andreas,


I just tested your solution by changing the architecture setting in XCode and it works fine. Thanks a lot ! Hope you can find the time to update the documentation with that piece of information.


Have a good day,


Amaury.
