- Update to latest version 6.08.00
- Now fully compatible with the new GCC ABI and Python3
- Applied custom patch to address JupyROOT issues (merge request is pending)

** Please do a clean build of this package! May require an uninstall to correctly accept new binary ABI!

@kgizdov I did remove root (yaourt -R root) when I tried before, but not its dependencies.
Doing a yaourt -Qdt and then yaourt -S root did the job for me.

Thanks for your help!

@ttekampe, please do a complete uninstall of root and try to build again - sudo pacman -Rns root

thanks a lot for maintaining this package!

Since the most recent update the compilation fails for me, saying that afterbase.h is missing:

@sfncmp1729, I am able to run jupyter myself, but since I do not use it normally, I do not have a script to test. In any case, this seem too specific. Let's move it over to email, so we can have a more productive conversation. If people really want this I might think about enabling it in root-extra. After all, that package exists to support as many features as possible, whereas this one is for the base ROOT build.

@kgizdov I see that python3 is more supported than I thought, thanks for your efforts to package ROOT with python3 support.

However I think that JupyROOT is still bounded to python2, indeed I get the same error which affects @hrocho with my own PKGBUILD (, which is built upon python2.

Moreover I was able to get JupyROOT working by manually renaming the python2 executable to python and by installing the `metakernel` python2 package (which is an undocumented dependency). Here it is a temporary PKGBUILD for this package:

If your PYTHONPATH is /usr/lib/root then it's correct and should not be touched. The paths are updated automatically in /etc/profile.d/ except if you're using Wayland. Wayland currently ignores the login shell scripts. The error you posted is specifically that the module does not exist. For me with http=OFF, it is not built, and that is expected behaviour. should not be setting your environment.

At the moment i can not check, but could be changed, and PYTHONPATH needa to be adjusted. Modules seems to be built.

@sfncmp1729, while Python3 compatibility has not been announced it's not "far from ready". You can check yourself in the recent issues on JIRA regarding this. The error is not caused by incompatibility, but because if you check CMakeCache.txt in the build directory you will find:
So the module is never built. Please add the flag to the settings.cmake as I suggested and try again. Let me know if it works OK, so I can update the package. I'm at a conference and cannot rebuilt myself at the moment.

The Jupyter problem is connected to fact that is assumed that "executable `python` is the executable of Python2" according to:

As far as I know the python 3 support is far from complete and there is no official announcement on the release notes.

If someone knows how to patch the JupyROOT stuff to make it work with python2, please consider sharing your patch, it would be very helpful.

kgizdov commented on 2016-11-16 11:05

It seems a lot of the defaults are changed and need to be given manually... The release notes didn't mention that. Could you try adding this to settings.cmake:

set (http ON CACHE BOOL "" FORCE)

Rebuild with makepkg -fC --skipchecksums
