<p>Hi Mainak,<br>

<p><br>
</p>
<p>Please continue to share your experiences with MITgcm on a M1 mac - you are a bit ahead of the curve here in<br>
</p>
<p>terms of what we're supporting at this point.<br>

<div>I also ran into a similar problem when compiling MITgcm on my</div>

</div>
<div>I fixed this by adding "#include <stdio.h>" to:</div>

</div>
<div><br>
</div>
<div>and adding the following lines to my optfile:</div>

FFLAGS="$FFLAGS -w -fallow-argument-mismatch -O2"<br>
FCFLAGS="$FCFLAGS -w -fallow-argument-mismatch -O2"</div>

Hi Mainak,<br>
<br>
I am not familiar with macbook, but the error you get might be<br>
due to a recent version of gcc (10 or above) for which we need a patch to the optfile,<br>
as proposed by Gael Forget here:<br>
<a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_MITgcm_MITgcm_pull_480&d=DwMFaQ&c=slrrB7dE8n7gBJbeO0g-IQ&r=ZvysV9sqKVa_ZzhPjngv7A&m=-6krWzaYhfDFZe5GZGpfvIMjmAhVO3v1BjE8STaN_BM&s=-sQexesGdxPZoN4TuLImRKBkgqjQBJiePAT4TQ0aSQQ&e=" rel="noreferrer" target="_blank">https://github.com/MITgcm/MITgcm/pull/480</a><br>
<br>
There might be other issues but hard to tell since it fails to compile<br>
early on because of this new gcc version.<br>
<br>
Also, I would suggest to try first without MPI to check that everything<br>
is in place and once you pass this stage you can try again with MPI.<br>
<br>
Cheers,<br>
Jean-Michel<br>
