Bug 298244 – dev-python/gmpy-1.14 fails to build with Python 3.2 (PyCObject)

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Arfrever Frehtes Taifersar Arahesis (RETIRED) 2009-12-24 18:46:42 UTC]

dev-python/gmpy doesn't work with Python 3.2. It uses PyCObject-related functions which are deprecated in Python 3.1 and removed in Python 3.2. PyCapsule-related functions should be used.

$ python3.2 -c 'import gmpy'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: /usr/lib64/python3.2/site-packages/gmpy.so: undefined symbol: PyCObject_FromVoidPtr

-Werror=implicit-function-declaration allows to reproduce this bug during building.

gmpy-1.11 is in portage, which compiles fine with python3.

[Comment 4 Arfrever Frehtes Taifersar Arahesis (RETIRED) 2010-05-07 16:54:07 UTC]

Building of gmpy extension now succeeds, but building of pysymbolicext extension fails.

src/pysymbolicext.c: In function ‘initpysymbolicext’:
src/pysymbolicext.c:441: error: implicit declaration of function ‘PyCObject_Check’
src/pysymbolicext.c:441: error: implicit declaration of function ‘PyCObject_AsVoidPtr’
src/pysymbolicext.c:441: warning: cast to pointer from integer of different size

since you added gmpy 1.12, is the bug still there?

[Comment 6 Arfrever Frehtes Taifersar Arahesis (RETIRED) 2010-07-21 15:49:58 UTC]

I updated summary.

[Comment 7 Stefan Briesenick (RETIRED) 2010-07-22 11:05:53 UTC]

ok, it's an incompability. What to do now? Try to fix it, or wait for new upstream release?

I can't test/do it, since python 3.2 isn't even in portage yet.

[Comment 8 Arfrever Frehtes Taifersar Arahesis (RETIRED) 2010-12-06 17:24:03 UTC]

Python 3.2_pre* is available in python overlay.

[Comment 9 casevh 2011-03-25 03:16:43 UTC]

(I'm the current maintainer of gmpy. I just stumbled across this bug. It wasn't reported upstream.)

pysymbolicext.c has been removed from the development version of gmpy 2.x (aka gmpy2) and should have been removed from 1.14. gmpy itself no longer uses PyCObject or PyCapsule functions.

Can the compiling of pysymbolicext.c just be removed from the build?

If not, would I need to release a new version that removes pysymbolicext.c?

(In reply to comment #9)

We thought that pysymbolicext extension is somehow useful. I have now disabled building of this extension.
