Problem installing PRESTO with Apple M2 - Ventura 13.2

I'm trying to install PRESTO on my Apple M2 laptop where it's installed os Ventura 13.2 Gfortran 12.2

Any suggestion to solve this issue?

[paulray]

Surely this is because M2 doesn't support precisions higher than REAL*8 (double). It does not have long double support. I don't know what the solution is, other than top compile it on another machine that is x86_64 then copy it to your M2 machine and hope that it runs OK under Rosetta.

[scottransom]

Yup. Agree with @paulray
