[Users] M1 Mac Compiling error

Wed May 25 10:36:11 CDT 2022

Hello,

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.

Hello David,

looking at your included output somehow clang got involved.

We do not actually document (or support) compiling the ET using clang
on a mac.

Last I heard was that someone did manage to compile the ET with the
latest release on a M1 mac using one of HomeBrew or MacPorts
(installing the packages listed at the top of:
https://github.com/nds-org/jupyter-et/blob/master/tutorial-server/notebooks/CactusTutorial.ipynb in the Prerequisites section).

Did you give that a try already?

Yours,
Roland

I’ve tried building from scratch several times using the real clean option between builds.  This is happening on 2 different computers and has been going on for weeks.

Superficially, this looks as if a file was miscompiled. This might
happen if you interrupt a build, and an incomplete object file is left
over. The next build might not detect this.

Starting a new build from scratch would then resolve this.

Hello,

I keep getting the errors below when I try to compile my ETK code on my M1 Macs. Any ideas on how to correct this?
