Hey guys,
I am new here and I have some problems installing ROOT via the instructions on official website(https://root.cern.ch/building-root).
I downloaded the latest ROOT version via Terminal from Github. Steps 2-4 works fine. In Step 5 I get some fatal errors which you can see below.
(work) sven@Svens-MacBook-Air ROOT_1 % sudo cmake --build . -- -j4

Do you have any idea what is going wrong there and what could be a solution for this?
