Hello pythonXY maintainers,
in python27, the LINKFORSHARED config variable is broken:
$ python2.7 -c "import distutils.sysconfig; \
conf = distutils.sysconfig.get_config_var; \
-u _PyMac_Error Python.framework/Versions/2.7/Python
This value cannot be used for linking. However, this is the exact
command that is used in the current macros in ax_python_devel.m4 from
autoconf-archive . With this value, linking a test program with
python27 will always fail.
All other python ports (really all of python24-26 and python31-36,
except python27) fix the LINKFORSHARED variable with a reinplace in
post-destroot. The very same reinplace existed in the python27 port, but
was removed in r108762:
* remove non-working attempt to change LINKFORSHARED. Any dependents
relying on this are broken anyway and should be fixed to get the
required info from python2.7-config (#39223)
I don't know what the correct solution would be, but either all python
ports should use the same approach (and have a broken LINKFORSHARED), or
python27 should also do what apparently works for the other ports.
This issue complicates writing ports with +pythonXY variants, as
+python27 needs to be special.
If LINKFORSHARED should really not be used, I would suggest to submit a
patch to autoconf-archive to get it fixed upstream instead of applying
workarounds in individual ports.
