py39

[james.franznick]

Was wondering if py39 lpp is available and the download link is just broken? Not seeing it in /tools

http://download.aixtools.net/tools/

[Michael]

Is now available as http://download.aixtools.net/tools/aixtools.python.py39.3.9.1.0.I - I still have to make the wiki page.

Hi, first of all thank you so much for your work.

Correct me if I'm wrong, but it seems like the last py39 build has been compiled in 32-bit mode; this is what I get on an AIX 5300-11-01-0944 machine:

Code: [Select]

>python3
Python 3.9.1 (tags/v3.9.1-dirty:1e5d33e9b9, Jan  4 2021, 13:53:54) [C] on aix
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.maxsize
2147483647
>>> sys.maxsize == 2**31-1
True
>>> import platform
>>> platform.architecture()
('32bit', '')

I figured this out when trying to compile the cx_Oracle module in 64-bit mode (CFLAGS="-q64" python3 setup.py build) and getting the error:

Code: [Select]

"/opt/include/python3.9/pyport.h", line 741.2: 1506-205 (S) #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)."

Do you think you'll be able to build a 64-bit package anytime soon?

[Michael]

I'll look at it later today. There were build issues re: 64-bit. Maybe they have been fixed.

[lmico]

Thanks!

Do you mean with Python 3.9.1?

[Michael]

Still facing build issues: py39-3.9.5:


root@x066:[/data/prj/python/py39-3.9.5]make
./python -E -S -m sysconfig --generate-posix-vars ;\
if test $? -ne 0 ; then \
        echo "generate-posix-vars failed" ; \
        rm -f ./pybuilddir.txt ; \
        exit 1 ; \
fi
/bin/sh: 3801144 Segmentation fault(coredump)
generate-posix-vars failed
make: *** [Makefile:619: pybuilddir.txt] Error 1


How about Python-3.8. iirc, that works as 64-bit.

FYI: I have tried to get some attention for the 64-bit build issues, but falls on deaf ears. Other people need to `complain`, as Python seems to think noone uses Python on AIX.

[Michael]

p.s. - This may be compiler specific (e.g., a compiler bug). I will retry with a try&buy xlc version, as I have seen it work with newer compilers.

What OS level of AIX are you running on? Just so I know my limitations.

[Michael]

I can build py38-3.8.10 in 64-bit, for sure.

I tried, as a test, py39-3.9.1 on a another system, but that failed as well.

[lmico]

Thank you very much for the effort.

How can one "lobby" about this? Do you know of a specific bug I can follow on the official tracker?

[Michael]

I'll look for an official bug report, or I'll make one. That will be next Monday.
