ROOT6 compilation on BeagleBone Black

[tlux]

Hi,

since a colleague is willing to provide us with a cosmic trigger system and the corresponding software he wrote for the readout, I am trying to install ROOT6 as required by the control software on a BeagleBone Black (Ubuntu 18.04 LTS) which has a AM3358 ARM Cortex-A8-MCU processor.

The installation of Ubuntu went quite smooth and also the start of the compilation of ROOT6 starts well but then I get the following error:

I checked on the forum for compiling on ARM and for Raspberry PI but did not find anything which could help me with this problem.

Anybody has an idea? Someone else tried to install ROOT6 on a BeagleBone Black?

Thanks

Thorsten

The compiler probably got killed due to memory usage, please try make -j1. ROOT works on ARM, @Axel actually compiled it on a Raspberry Pi Zero before. Also make sure you use a Release build, as debug builds require more memory.

[binet]

and if make -j1 doesn’t work, remember there’s also:

• cross compilation
• groot (which is inches from getting write support for ttrees)

[Axel]

@binet and there is Mathematica which is likely as relevant to this topic

[Axel]

Back on topic, indeed this looks like a memory issue. We might be able to provide you with a binary. Let me look into this next week. Is there a certain ROOT version you need?

[Wile_E_Coyote]

I need a ROOT 6.18/00 “binary” for Ubuntu 14.04 / x86_64.

[tlux]

Dear Axel,

no, it seems no special ROOT6 version needed. Any should do it.

Thanks a lot!

Thorsten

[eguiraud]

A bit off-topic, but you should be able to get ROOT v6.18 on Ubuntu 14.04 via conda (conda install -c conda-forge root).

Cheers,
Enrico

[Axel]

I was hoping that you could use a Raspberry build - but I learned that this won’t work. So indeed - you’d have to build it yourself, or pull one from conda if you have that on your BeagleBone.

The error you see is either out of memory or a power issue. How much RAM do you have? If all fails you could create additional swap space on an SDD that you connect to your BeagleBone.

[Axel]

@Wile_E_Coyote I have added an Ubuntu 14 build to https://root.cern.ch/content/release-61800 - enjoy!

[Wile_E_Coyote]

@Axel Thanks, I was now able to improve the bug report here:

Cannot write histograms in the file because of opening another root file

@axel @pcanal It seems that opening a file produced by ROOT 6.14/06 or 6.16/00 (files from ROOT 6.12/06 and earlier releases and also ROOT 6.18/00 seem fine) in ROOT 5 is sufficient to screw the old ROOT 5 so that it is unable to properly save its newly created histograms in its newly created file (e.g. in ROOT 5.34/36 or the current “v5-34-00-patches” branch). Here’s a simple standalone trial.cxx (987 Bytes) macro which reproduces this problem (it needs the standard “hsimple.root” file from R…

Does conda build ROOT for arm/arm64 as well as x86?

[eguiraud]

Definitely not x86, not sure about arm – I was replying to the request for v6.18 on ubuntu 14.04/x86_64
