#57096 assigned defect

root6 6.14.02 installed with python36 variant when python34 variant is specified

Reported by: AlexanderLarsRobinson (Alexander Lars Robinson) Owned by: cjones051073 (Chris Jones)
Priority: Normal Milestone:
Component: ports Version: 2.5.3
Keywords: Cc: mojca (Mojca Miklavec)
Port: root6

Description (last modified by AlexanderLarsRobinson (Alexander Lars Robinson))

root6 was upgraded from 6.10.08 on my machine (MacOS Sierra 10.12.6) to 6.14.02, but the installation automatically switched the root6 variant from python34 to python36. Manually specifying the python34 variant results in the installation of the python36 variant instead as well.


sudo port install root6 @6.14.02_1+cocoa+cxx17+gcc7+graphviz+gsl+http+minuit2+opengl+python34+roofit+soversion+ssl+tmva+veccore+xml+xrootd


Installing root6 @6.14.02_1+cocoa+cxx17+gcc7+graphviz+gsl+http+minuit2+opengl+python36+roofit+soversion+ssl+tmva+veccore+xml+xrootd

This is highly undesirable behaviour, as an upgrade to one package is, in effect, removing a necessary python package and thus breaking everything.

the python34 variant is no longer offered. It was dropped a while back in a general ratification of the variants. only 27, 3.5 3.6 and 3.7 are now offered.

This is why it changed for your, as the variant you had no longer exists the default is used instead.

I am having an severe memory-handling error in the interaction of root6 6.14.02 with python36. I cannot install the python34 variant of root6 6.14.02, nor can I install the python36 variant of any earlier version of root6. In both cases root6 @6.14.02+python36 is installed. It is thus impossible for me to determine what the cause of this error is, and whether a version change in root6 or its python interface will solve it. This is incredibly inconvenient.

By all means checkout the Portfile for root6 and try adding back the older python variant for yourself. You then should be able to try installing it with the newer root6 release.

I'm trying the other python versions before I try to figure out how the portfiles work.

Also: the python37 variant of root6 returned Error: Dependency 'py37-metakernel' not found.. I don't feel like submitting another ticket.

I hope I fixed the dependencies for python 3.7
