[Users] M1 Mac Compiling error

[Roland Haas]

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
