Error compiling with Ubuntu 20.04.4 LTS on virtual machine

MassimilianoAntonell · March 11, 2022, 3:24pm

ROOT Version: 6.18.00
Platform: Ubuntu 20.04.4_ARM (virtualized with Parallels from a Mac M1 PRO)
Compiler: gcc(g++) 9.4.0

Goodmorning,
I just received my new MAC Book PRO with M1 PRO chip and I’m trying to install root on a virtual machine (with Parallels) of Ubuntu 20.04.4 LTS.
I downloaded the source code from: root.cern/releases/release-61800/
I need to make this option (needed for the analysis tool we have in lab):

cmake -DCMAKE_INSTALL_PREFIX=/home/cmspix/daq/root-6.18.00/install -DPYTHON_EXECUTABLE=/usr/bin/python3 --enable-minuit2 -DCMAKE_CXX_STANDARD=17 -Ddavix=off ..

Everything seems fine and when I run:

cmake --build . --target install -j4

It start compiling but it stops here:

Do you have some suggestions? What I’m doing wrong?
Thanks for your help and time!

Maybe @axel knows if 6.18.00 is supported on ARM, but meanwhile you can try to disable ssl (-Dbuiltin_ssl=OFF)

MassimilianoAntonell · March 11, 2022, 3:43pm

Thanks, I’m trying but with no success… Anyway yesterday I managed to install both 6.26 and 6.18 but for a bug in the virtual machine I lost everything and I started again from scratch but now I’m stacked here =(

FWIW, and depending on what you want to do, Go-HEP/groot may be an option:

it’s in Go instead of C++,
it can read and write ROOT files (that are readable by C++/ROOT),
and it can be installed on {Linux,Darwin,Windows}/{amd64,arm,arm64,386} (and even cross-compiled from one to the other)

bellenot · March 11, 2022, 3:50pm

Did you install the binaries or did you build from source?

MassimilianoAntonell · March 11, 2022, 3:51pm

I need to build from source for some compatibility with my analysis framework

MassimilianoAntonell · March 11, 2022, 3:54pm

It gives me the same error:

OK, I have no experience with Ubuntu 20.04.4_ARM but maybe you can try to install ssl in your VM and try again. Otherwise I’ll let @axel comment on this

MassimilianoAntonell · March 11, 2022, 4:00pm

If it could help:
The verison I’m using is the default after the installation of all the root dependencies as reported in the web site:

MassimilianoAntonell · March 11, 2022, 4:53pm

I obtain the same error also trying with a new virtual machine and Openssl 1.1.1.f

Axel · March 13, 2022, 1:16pm

Let’s first fix your CMake configuration such that it uses your distro’s openssl. Can you share your cmake invocation and your CMakeCache.txt?

MassimilianoAntonell · March 13, 2022, 1:53pm

Hi! Thanks for the reply but I managed to install root using an old version of the Ubuntu kernel (I honestly don’t know what I did wrong before).
