Mathematica 14 breaks upon startup on Raspberry Pi 5

Michael Byczkowski
Posted 1 year ago

Great having Mathematica 14 now also available for the Raspberry Pi, thank you very much!

The only problem is that when starting an upgraded install (from 13.3.1). it stops with a series of errors, the first shown in the screenshot (I'm not using walynd but the old X/VNC combo). Mathematica 14 startup error

Thanks for your help,
Michael

Update: yes, lixcb-randr0 is installed and RandR=1280×800 is now set in the options of my RealVNC Server 7.10.0.52269 for arm64.

But no change, same error.

Just to add: 13.3.1 ran flawlessly w/o setting RandR or anything else.

Does your VNC server support randr? For example in the RealVNC case, you may try specifying the geometry with something like

vncserver-virtual -RandR=1280×800

This works fine for me, using the built-in realvnc server paclage

vncserver-virtual -RandR=1280x800
RealVNC(R) Server 7.5.1 (r50075) ARMv8-A (May 30 2023 13:27:57)
Copyright (C) RealVNC Ltd.

OS: Debian GNU/Linux 12, Linux 6.6.20+rpt, aarch64

P.S.: Besides, I just noticed that while wolfram-engine for arm64 is @ 14.0.0+202403231274, wolframscript for arm64 is still @ 13.3.1+20230821180 on the standard feed.

By the way, you don't necessarily need the standalone wolframscript package any more. There is an up to date version of wolframscript included in the wolfram-engine package

Setting up wolfram-engine (14.0.0+202403231274) ...
update-alternatives: using /opt/Wolfram/WolframEngine/14.0/SystemFiles/Kernel/Binaries/Linux-ARM64/wolframscript to provide /usr/bin/wolframscript (wolframscript) in auto mode
POSTED BY: Ilian Gachevski

Yes, agreed; might be good to remove wolframscript from the feed, though?
POSTED BY: Michael Byczkowski

The latest version of the wolframscript package has been published in the official repository.

While it is not necessarily needed or useful when wolfram-engine is already installed, there is also the possibility of cloud kernel use, i.e. wolframscript -cloud without a full local installation.

Thank you, Stefan, and no, libxcb-randr is not available on the standard feed of Raspberry Pi/Debian and therefore also not installed, I'm sorry.

Best regards, Michael
POSTED BY: Michael Byczkowski

I think Stefan meant the libxcb-randr0 package
POSTED BY: Ilian Gachevski

Hi, Michael!

Could you double check that you:

a) have libxcb-randr installed

b) the vnc server is using it
