[Gate-users] GATE on Raspberry Pi

[David Boersma]

Hi Andrew,

How cool, that you were able to install Gate on a Raspberry Pi!

In order to address your issue, we need to be able to reproduce your error. I am suspecting that this crash is not due to the hardware that it runs on, but due to incorrect usage. Ideally, incorrect use should result in informative error messages, but unfortunately Gate does not always check all its inputs, which especially for new users can easily result in such crashes. We hope to gradually improve on this, but it will take time.

(1) which version did you install (a release, or develop branch from git)?
(2) could you create a short Gate macro that we can use to reproduce this crash?

Thanks!
David

Dear Gate-ers

I’m trying to get GATE running on a Pi, all seems to run OK until I try to read out data from the simulation using an Actor.  I then get the error message:

*** Break *** segmentation violation

I have Gate 8.1, Geant4 10.3.03, and Root 6.12/06 running on a Pi 3 B+
Has anyone seen something similar before, or can point me towards a way to solve this issue?

Thanks
Andrew
