I wanted to compile cernroot on ubuntu with python3 bindings for ROOT (pyROOT).
This is what worked for me (i built it in a docker container):
apt-get update && \ apt-get -y install \ vim \ nano \ libgslcblas0 \ python3-numpy \ python3-scipy \ python3-matplotlib \ perl \ bc \ git \ liblapack3 \ libboost-all-dev \ gv ghostscript xterm x11-utils \ dialog \ python3-pip \ wget \ git dpkg-dev cmake g++ gcc binutils libx11-dev libxpm-dev \ libxft-dev libxext-dev wget https://root.cern/download/root_v6.18.02.source.tar.gz && tar -zxvf root_v6.18.02.source.tar.gz && rm root_v6.18.02.source.tar.gz mkdir /root-build && cd /root-build; cmake -DPYTHON_EXECUTABLE=/usr/bin/python3 ../root-6.18.02 cd /root-build; make -j6
Let’s go ahead and test it:
micha@5be8c924103b:/$ . /root-build/bin/thisroot.sh
micha@5be8c924103b:/$ python3

>>> import ROOT
>>> ROOT.TBrowser()
<ROOT.TBrowser object ("Browser") at 0x35d8560>
>>>
…. a TBrowser window opens … it is working
