Hello all.
My system is FreeBSD 11.2-RELEASE-p9 AMD64. I update my ports tree with
portsnap and build my ports with portmaster. For several days I have been
trying to resolve a problem updating ffmpeg.
ffmpeg requires audio/lv2
lv2 requires textproc/py-rdflib
According to the data in the Freshports site, lv2 has a runtime dependency
on py36-rdflib but py-rdflib has build- and runtime dependencies on
lang/python27, and its package name is py27-rdflib.
Hi Luis,
I *think* the latter case (rdflib looking like it depends on python27 at
freshports) is an artifact of the port not having been updated since
June 2018, which was before the Python default version switch this year,
and freshports not having regenerated/refreshed the page/information for
the port.
Portmaster emits the following error compiling py-rdflib:
pkg-static: py36-rdflib-4.2.2 conflicts with py27-rdflib-4.2.2
(installs files into the same place). Problematic file: /usr/local/bin/csv2rdf
*** Error code 70
It's likely the case that you have py27-rdflib installed at the moment,
and since the default version of Python has switched to 3.6, it now
conflicts.
See: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=226634#c10 for
the details explanation (it applies to any python package, not just
setuptools)
What do you currently have set in /etc/make.conf for DEFAULT_VERSIONS ?
I have checked the UPDATING file and found no answer. Is there some standard
method for dealing with python27 vs. python36 conflicts, or is this a bug in the
lv2 dependencies that must be fixed by the maintainer?
Python ports/packages that install things in LOCALBASE/bin should be
made concurrent safe, and the py-rdflib isn't.
I'll sort that out shortly, which will address the conflict, where only
the *default version of the port/package will have the
version-suffixless name.
