Error Building Sample Project – "Undefined symbols for architecture arm64"

[ryanhuman]

Hey – this project seems great! I’ve had success downloading it and doing a build for the iPhone6 Simulator, but when I try to build to a device I get an error (pasted below) that suggests it OpenEars isn’t arm64 compatible – contrary to what I’ve read elsewhere. Any advice?

ld: warning: ignoring file ../OpenEarsDistribution/Framework/OpenEars.framework/OpenEars, missing required architecture arm64 in file ../OpenEarsDistribution/Framework/OpenEars.framework/OpenEars (2 slices)

Welcome,

The sample app builds out of the box without any modifications, so generally something like that can only happen if it has been modified or parts of it have been moved. The safe bet is just to delete it and download a new one and start over, it should work fine.
