[GRASS-user] Rosetta Error in "r.fill.dir"

[Nicklas Larsson]

Daniel,

I couldn’t reproduce your issue with a random dem. It would be good if you could share a minimal data set causing the crash for testing.

Also, please take a look if there is a more detailed crash report with '/Applications/Utilities/Console.app’ and share its content.

If this is indeed a Rosetta related issue, an immediate solution would be to install the ‘grass’ port with MacPorts [1], which installs in native architecture also for M1’s.

Side note: The official GRASS Mac app bundle, is based on miniconda for its dependencies. Last time I tried there were issues with arm support for especially condas wxPython, therefore it is still only built for x64.


Best,
Nicklas

I sense this is an error with Rosetta and the M1 chip, but have not received such an error prior on this computer. I have also tried running the module through GRASS 7.6 and 7.8, but am having no luck due to segmentation fault errors.
