faust2unity iOS plugin linking error #638

Closed marvpaul closed 2 years ago

marvpaul commented 3 years ago

I used the faust2unity script to generate a UnityPackage which I imported into my Unity project (Unity 2020.3.0f1). I used the following command: ./faust2unity -ios -osx -nvoices 6 synth3.dsp

After importing the package I tried to build an iOS app. The resulting xCode project fails to build while linking. I got the following error: 

ld: warning: object file (/Users/marvinkruger/SCSynth/buildFaust2/Libraries/Plugins/FaustPlugin_synth3/iOS/libFaustPlugin_synth3.a(synth3.o)) was built for newer iOS version (14.5) than being linked (11.0)

Is this a problem with the faust2unity / generated iOS plugin or did I missed something here?
