Hello,
I am trying to create ROOT from the source in Order to use Pyroot.
While running cmake – build . --target install i get the following error:
[ 90%] Building CXX object tmva/tmva/CMakeFiles/TMVA.dir/src/NeuralNet.cxx.o

make: *** [Makefile:171: all] Fehler 2
Has anyone an Idea how i can fix this?
And would it be possible to use a prebuild version of ROOT in order to use Pyroot?
Thank you for your answers and your help.
