Boost::python does support python3 If you want python3 support on cython, you'll need to ask upstream. Asking here won't do it. Perhaps I did not make myself completely and perfectly clear. I assumed some level of assuming the bug reporter was not a complete idiot on the part of Fedora packagers. Both Boost::python and Cython upstream support Python3. http://wiki.cython.org/FAQ#WhatPythonversionsdoesCythonsupport.3F I am not asking Fedora to magically add support to a package that does not support it. I'm asking for a Fedora package that supports it. Boost::python is packaged like a C++ library. It would be hard to have two versions of the shared library, one for Python 3 and one for Python 2.7. Cython is packaged like a Python package. So the techniques that are used to allow, say, a python3-paste and python-paste would work for Cython. Cython already supports Python 3.2. Could you please create a package for a version of Cython compiled to support Python 3.2? Perhaps Cython-py3 would be a good package name. [Trying to clear the air a little here; the tone in the discussion so far seems
to have been rather unpleasant, alas. Please be respectful.]
What cython "support for Python 3.2" means is a little ambiguous to me.
It could mean:
(A) ...that the generated C source code is compilable against python 3's
headers and libpython3.* As I understand it, Cython can already do
this: it generates C code that is compilable against both 2 and 3, and
ought to work with 2.7 and 3.2 (you have to compile it twice though,
as the ABIs are different) - Cython does all the work of handling the
API differences between the 2.7 and 3.2 header files. I believe that
modules generated using Cython have no run-time requirement on Cython.
(B) ...that the Python code for Cython is implemented in Python 3 rather
than Python 2. Currently in $(rpm -qlv Cython) on this F15 box I see
a hierarchy of Python modules under:
/usr/lib64/python2.7/site-packages/Cython
which is clearly for Python 2. I don't know if Cython can be run
_using_ Python 3; if it doesn't that would require fixing upstream.
Based on comment #0, it sounds like the reporter is interested in case (A)
above, which ought to already work, without requiring further work on the
Cython rpm.
Did I characterize the requirements correctly? (setting "needinfo" flag on the reporter)
[Hope this is helpful]

I did not realize that things would work this way. I will try to some test cases and verify that you are correct. This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
