ROOT and Catalina

ROOT

Dear ROOTers,

after the “downgrade” to Catalina of my Macbook Pro, I updated the ROOT installation following this:

and the result of this sequence of operations is that I cannot compile any longer (error messages are reported below) [2].
Also, the interactive root does not work any longer [1].

Would you please point me to a set of instructions I could follow, to have my root back into shape?

Best regards,

pietro

I wonder if the right version of ROOT is picked up. Could you please call

which root
root-config --version

The Catalina pre-release from the referenced post should end up in /Applications/root_v6.18.99, so that it can be enabled by

source /Applications/root_v6.18.99/bin/thisroot.sh

Thanks Jakob,

you’re right, I managed to fix the issue with the correct source in the .profile file.
