According to recent tests, this case now works fine, so there's no reason
to reject it anymore. (Even if there are still some OpenBSD platforms
in the wild where it doesn't work, removing the check won't break any case
that worked before.)
We can actually remove the entire test that discovers whether libpython
is threaded, since without the OpenBSD case there's no need to know that
at all.
Per report from Davin Potts. Back-patch to all active branches.
As of Xcode 5.0, Apple isn't including the Python framework as part of the
SDK-level files, which means that linking to it might fail depending on
whether Xcode thinks you've selected a specific SDK version. According to
their Tech Note 2328, they've basically deprecated the framework method of
linking to libpython and are telling people to link to the shared library
normally. (I'm pretty sure this is in direct contradiction to the advice
they were giving a few years ago, but whatever.) Testing says that this
approach works fine at least as far back as OS X 10.4.11, so let's just
rip out the framework special case entirely. We do still need a special
case to decide that OS X provides a shared library at all, unfortunately
(I wonder why the distutils check doesn't work ...). But this is still
less of a special case than before, so it's fine.
Back-patch to all supported branches, since we'll doubtless be hearing
about this more as more people update to recent Xcode.
Pre-Lion versions of Apple's linker don't allow space between -F and its
argument. (Snow Leopard is nice enough to tell you that in so many words,
but older versions just fail with very obscure link errors, as seen on
buildfarm member locust for instance.) Oversight in commit
fc8745070a.
The PL/Python build on OS X was previously hardcoded to use the system
installation of Python, ignoring whatever was specified to configure.
Except that it would use the header files from configure, which could
lead to mismatches. It was not possible to build against a custom
Python installation.
Now, we check in configure how the specified Python installation was
built and use that, supporting framework and non-framework builds.
Python can be built to have two separate include directories: one for
platform-independent files and one for platform-specific files. So
far, this has apparently never mattered for a PL/Python build. But
with the new multi-arch Python packages in Debian and Ubuntu, this is
becoming the standard configuration on these platforms, so we must
check these directories separately to be able to build there.
Also add a bit of reporting in configure to be able to see better what
is going on with this.
Because of ABI tagging, the library version number might no longer be
exactly the Python version number, so do extra lookups. This affects
installations without a shared library, such as ActiveState's
installer.
Also update the way to detect the location of the 'config' directory,
which can also be versioned.

This variable is apparently only for Python internally. In newer releases
of Python this variable pulls in more and more libraries that users are
less likely to have, leading to potential build failures.
Behaves more or less unchanged compared to Python 2, but the new language
variant is called plpython3u. Documentation describing the naming scheme
is included.
shell construct to hide away the stderr output. Python 3.1 actually core
dumps on the current invocation (http://bugs.python.org/issue7111), but the
new version also has the more general advantage of saving the error message
in config.log for analysis.
print foo --> print(foo)
string.join(...) --> ' '.join(...)
These changes are backward compatible.
The actual plpython module appears to need significant updates to support
Python 3.0, though. This change just relieves interested developers from
having to deal with Autoconf.
-L spec rather than assuming libpython is in the standard search path
(this returns to the way 7.4 did it). But check the distutils output
to see if it looks like Python has built a shared library, and if so
link with that instead of the probably-not-shared library found in
configdir.
choice of compiler and flags, uninstall, and peculiar Python installation
layouts for PyGreSql. Also install into site-packages now, as officially
recommended. And pgdb.py is also installed now, used to be forgotten.
that now functions as a wrapper around the MakeMaker stuff. It might
even behave sensically when we have separate build dirs. Same for plperl,
which of course still doesn't work very well. Made sure that plperl
respects the choice of --libdir.
Added --with-python to automatically build and install the Python interface.
Works similarly to the Perl5 stuff.
Moved the burden of the distclean targets lower down into the source tree.
Eventually, each make file should have its own.
Added automatic remaking of makefiles and configure. Currently only for the
top-level because of a bug(?) in Autoconf. Use GNU `missing' to work around
missing autoconf and aclocal. Start factoring out macros into their own
config/*.m4 files to increase readability and organization.
