I tried updating from morty to rocko, and no longer got this error. So it seems it's somehow an issue with meta-mono in conjunction with morty.

That’s due to the fact that Rocko onwards OE switched to using recipe specific sysroots

Hey Craig,

There was an separate issue with the morty branch building which hopefully I've resolved with a recent cherry-pick.

I'm not intending atm to update support for more recent releases of Mono on Morty due to the issue you've identified above.

(This is because I think it's more valuable to put the time I have available into supporting the current Mono release on master, T-P etc. - which I'll hopefully be looking at shortly).

I'd be very pleased to receive PRs though if you have the time to address this...



Thank you for the information.

What is the cherry-pick which hopefully resolved this issue?

I can’t provide a PR since I don’t understand the problem at this point. But, I agree it’s probably not spending effort on morty since I think its support will end soon. I’m in the process of updating to rocko.

Regards,
Craig
