Dockerfile for rootproject/root-ubuntu16

ROOT
1

Hello, where can I find the Dockerfile for rootproject/root-ubuntu16 ?

2

At the moment the files are here: https://github.com/root-project/rootspi/tree/master/docker. The image is built in two stages, one with the dependencies, and another with ROOT itself. I am thinking about moving them into a separate repository when I create similar files for other Linux distributions. If you want a self-contained file, you can start with the one below. Cheers,

Thank you. Here

I am not sure to understand when the building is done. You copy the build.sh but don’t you execute it?

4

We have a separate job in Jenkins that executes it. That’s why I also provided something you can use with docker build standalone.

5

thank you. Do you know why if inside the image, after the installation, I do python import ROOT it doesn’t work?

6

found it, I had to add

ENV PYTHONPATH /usr/local/lib

as in https://github.com/root-project/rootspi/blob/master/docker/ubuntu16/Dockerfile

additional problem. ROOT works inside the image, but not with python (2 or 3)

>>> import ROOT
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/ROOT.py", line 24, in <module>
    import cppyy
  File "/usr/local/lib/cppyy.py", line 60, in <module>
    import libPyROOT as _backend
ImportError: libTree.so: cannot open shared object file: No such file or directory

PYTHONPATH is set to /usr/local/lib where I have ROOT.py. libTree.so is in the same directory

If I do

LD_LIBRARY_PATH=/usr/local/lib/

then it works, but I would like to avoid it. Is there something I can change in your Dockerfile?
