Hello,
<div class=""><br class="">
</div>
<div class="">I’ve got 3 M1 Macs. A 2021 MacBook Air with an M1 and over 20 years of Time Machine backups, a 2021 iMac with an M1 and a different set of old Time Machine backups and a brand new 2022 MacBook Pro with an M1 Max and a fresh OS with no legacy
files. For some reason, I only got ET to compile on the MacBook Air. I have no idea why this is. The other 2 give me the error that I shared. I tried using HomeBrew and MacPorts as well as Intel’s OneApi on each of these. I’ll check out the link you sent
to see if I missed anything. It would be good to have some documentation on how to install ET on a fresh M1 since that is the first sub-$1000 Mac that seems to be able to effectively run ET code.</div>

Superficially, this looks as if a file was miscompiled. This might<br class="">
happen if you interrupt a build, and an incomplete object file is left<br class="">
over. The next build might not detect this.<br class="">
<br class="">
Starting a new build from scratch would then resolve this.<br class="">
