Face detection example compile error with gapsdk 3.6 about aideck-gap8-examples

[knmcguire]

Hi! Thank you for letting us know. The face detection example was last tested on the SDK version 3.4. I indeed got the same error as you did on 3.5 already. I also have 18.04 and after downgrading the sdk to 3.4, (and make gap_tools), it compiled for me.

I will update the documentation to state this, since the SDK version was not displayed there. In the mean time we will look into updating the example to work for 3.6

My latest commit should solve your problem. I couldn't test it on 3.6 since I got some build issues on that version, so this was tested on 3.5, but I hope it works on 3.6

[knmcguire]

Could you give us an update if this works for you so that we can close the issue?

hello i am still having issues, but i think it is due to the compiler i am using (espressif esp 32) i followed your advice and downgraded to version 3.5 and reinstalled the examples folder and the previous problem dissappeared. i think we can close this issue. i will let you know how i am progressing. thank you for your help.

Ah oke good!

Is the espressif compiler for the NINA? You could open up a new issue about that if you want, but we will close this one.
