Hello Mario,

are you compiling using gcc-10 and gfortran-10 by any chance?

Then please see here for a workaround:

https://bitbucket.org/einsteintoolkit/tickets/issues/2403/compile-failure-wi...

https://bitbucket.org/einsteintoolkit/tickets/issues/2406/cactus-fails-to-li...

basically by adding -fcommon and -fallow-argument-mismatch to the compiler flags.

The tutorial notebook

https://github.com/nds-org/jupyter-et/blob/master/CactusTutorial.ipynb

also contains information on the workaround.

A proper fix is ready to be deployed to the released code but we were holding off until after the workshop to not accidentally introduce more (unknown) issues on top of the one for which we have a workaround.

Yours, Roland

Hi,

I’m setting up the ET for the first time in preparation for the upcoming workshop tutorials, and I’ve ran into some “mismatch” issues (see attached screenshot) upon executing the following command line:

./simfactory/bin/sim build -j2 --thornlist ../einsteintoolkit_08_2020.th

The error messages give no indication whatsoever as to how to fix them, so I’m at a loss here. Any help would be much appreciated.

Best, Mario
