I am installing root on my laptop which runs the latest version of macOS (Big Sur 11.4). I need root for python3 so I am trying to build it and was using the following commands:
git clone GitHub - root-project/root: The official repository for ROOT: analyzing, storing and visualizing big data, scientifically
mkdir build
cd build
cmake …/root
make -j8
cmake didn’t give any warnings but the build failed at 90%. I pasted the last bit of output below
