[issue28311] AIX shared library extension modules installation broken - Python2.7

[Martin Panter]

Martin Panter added the comment:

I think this might be separate to Issue 25825, but my investigation at 
 may be relevant. Following on 
from that, I reopened Issue 18235, which seems to be about the same LDSHARED vs 
BLDSHARED problem, but never fixed in 2.7.

[issue28311] AIX shared library extension modules installation broken - Python2.7

[Michael Felt]

New submission from Michael Felt:

issue#25825 is closed - and had python2.7 removed - so, want to mention there 
is something broken - a long time it would seem on AIX - for building packages 
after python and ensurepip are installed.

Currently trying to pip install mercurial; later a regular "make build"

PIP INSTALL

running build_ext
building 'mercurial.base85' extension

Problem seems to be in _sysconfigdata.py

root@x064:[/opt/lib/python2.7]grep ld_so_aix *.py
_sysconfigdata.py: 'BLDSHARED': './Modules/ld_so_aix xlc_r 
-bI:./Modules/python.exp',
_sysconfigdata.py: 'LDCXXSHARED': '/opt/lib/python2.7/config/ld_so_aix xlc_r 
-bI:/opt/lib/python2.7/config/python.exp',
_sysconfigdata.py: 'LDSHARED': './Modules/ld_so_aix xlc_r 
-bI:./Modules/python.exp',

SOLUTION:
set LDSHARED to same value as LDSHARED, i.e.,
'LDSHARED': '/opt/lib/python2.7/config/ld_so_aix xlc_r 
-bI:/opt/lib/python2.7/config/python.exp'

If this has already be done for Python2.7 - then perhaps issue#25825 should 
have Python2.7 restored - and this closed.

Otherwise - please repair.
