O2 installation crashes at ROOT6 - MacOS Mojave

O²
1

Dear all,

I am trying to install O2 in my Mac (MacOS Mojave) through the command

aliBuild build O2Suite --defaults o2-dataflow

aliDoctor response is ok (only some warnings), but the building fails at ROOT6 ( ROOT@v6-20-02-alice3) with the log

Does anyone have any suggestion on how to fix it?

Thanks a lot in advance,

silvia

Dear silvia,

it looks like you have root installed from the system and sourced when you start compiling with aliBuild. Can you disable that?

Dear Giulio,

thanks a lot for the feedback. Looking into my bash configuration file, .bashrc (I work with the bash shell:

garibaldi:~ pisanos$ echo SHELL /bin/bash garibaldi:~ pisanos

) I see

export PATH="/usr/local/opt/gettext/bin:/usr/local/bin:$PATH"

Execute alidock within the appropriate Python virtual environment

function alidock() {( source “/Users/pisanos/.virtualenvs/alidock/bin/activate” && command alidock "@"; exit ?; )}

source /usr/local/root/bin/thisroot.sh

export ALIBUILD_WORK_DIR="$HOME/alice/sw"
eval “alienv shell-helper”

export PATH="/usr/local/sbin:$PATH"

I tried to comment/remove the line

source /usr/local/root/bin/thisroot.sh

and reopen a new terminal, but I got the same error message as before when trying to build O2. Actually, even if I open a new terminal after the modification, I still see my ROOTSYS variable set to

garibaldi:alice pisanos$ echo ROOTSYS /usr/local/root garibaldi:alice pisanos

Isn’t it the proper way to implement your suggestion? If not, could you indicate me the correct one?

Thanks a lot in advance,

silvia

Can you please reformat your message using code blocks?

I am not sure how you can get ROOTSYS in the environment. Maybe you have something else setting it?

Hello Silvia,
in case you havent found a solution yet, I had the same issue:

TGLIncludes.h:21:10: fatal error: 'GL/glew.h' file not found
#include <GL/glew.h>
         ^~~~~~~~~~~
1 error generated.

You can fix this by adding the following line to root.sh in alidist:


There seems to be some kind of incompatibility when cmake tries to find a system version of glew on Mac. Current root master would give you a warning about this:

Hope this helps.
Cheers,
Mario
