[issue9419] RUNSHARED needs LDFLAGS

[Irit Katriel]

Irit Katriel  added the comment:

Closing as 2.7 is past EOL and distutils is deprecated. Please create a new 
issue, and include complete reproduction instructions, if you are seeing this 
problem on an up to date version (3.9+).

Yes Peter, build outside source tree fail for,  fail for me and pass for python 
developers :). So no idea how to convince them to fix this issue.

Next is from my sources for python 2.7

I am collecting out of tree build failures in issue 9860.  One issue that is 
easily reproducible is triggered when there are object files in the tree from 
another build, but it looks like you see something else.

As for convincing developers to fix a bug, the best approach is to propose a 
patch! :-)

Peter, please explain exactly how you built Python to trigger this bug.  I.e. 
include the exact commands and directories you used.  I cannot reproduce this 
yet.

LDFLAGS make no sense for run time. The patch seems to me bogus.

[issue9419] RUNSHARED needs LDFLAGS

[Peter Häring]

New submission from Peter Häring p.haer...@gmx.net:

test_distutils fails with 2.7 on a shared build (at least if building outside 
the source tree), 2.6 versions work. The reason for this is, that the test 
tries to link and doesn't find libpython-2.7.so.1.

A solution (or workaround) is to add LDFLAGS=-L`pwd` to the variable RUNSHARED, 
as I did in the attached file for SUNOS and GNU/Linux etc. Other systems 
probably need some similar patch.
