Dear Experts!

While trying to compile for a BSM process, I am getting an error as follows:

Error detected in "generate_events run_01"

I have checked already the compatibilities. Still unable to diagnose the issue.

Hi,

So this seems to be a compatibility of your compiler and SDK.
Related likely that one is targeting intel chip and the other one arm chip.

So the solution is likely to re-install a version of gfortran compatible with your SDK.

I have the weird feeling that your SDK is targetting intel, are you on an intel mac? (in that case it would make sense).
But I can be wrong on this since I do not have that much experience in those type of error message (which to be honest are not related to our code).

Cheers,

Olivier
