python25 does not provide a dynamic library

[nox@…]

python2.5-config --libs talks about a "python2.5" library.

The python2.5-config script says:

elif opt in ('--libs', '--ldflags'):
    libs = getvar('LIBS').split() + getvar('SYSLIBS').split()
    libs.append('-lpython'+pyver)
    # add the prefix/lib/pythonX.Y/config dir, but only if there is no
    # shared library in prefix/lib/.
    if opt == '--ldflags' and not getvar('Py_ENABLE_SHARED'):
        libs.insert(0, '-L' + getvar('LIBPL'))
    print ' '.join(libs)

As you can see, if python is built with Py_ENABLE_SHARED set, it should provide a dynamic library. If not, it should include in the LDFLAGS the lib/python2.5/config directory, where lives libpython2.5.a.

Unfortunately, python25 build system assumes that if you're on Darwin, you're more likely to build Python as a framework, and so it forgets about dynamic library when building it the old-fashioned Unix way.

Finally, Py_ENABLE_SHARED is set because configure has been asked to (configure.args --enable-shared, but the only thing that get changed is that modules are built as bundles.

I've tried writing a patch (attached) about that but it fails when building.

So, we either found a way to build a nice and neat dylib, or we move to framework-style install.

So, with some more work and a nice patch from the Fink team (I think), I've been able to build and install a dynamic library.
But that's not all there is about this last patch:

• Added gettext dependency (needed for the _locale core module).
• Now uses altinstall make target: this target installs the Python interpreter as python2.5 thus removing the need of patching Makefile.pre.in to avoid conflicts with other python2* ports.
• Added 2 source patches to workaround the lack of environ global array on Darwin.
• Removed call to system to rename the other executables and the manpage.
• Removed useless configure arguments (they were either not defined or enabled by default).
• Modified livecheck a bit to something more beautiful and correctly escaped.

Hope you'll be able to review this bunch of patches easily, otherwise i'll split them up a little.

The Makefile.pre.in patch now also disable the installation of lib-tk and sqlite3 directories, as these modules are disabled anyway.

[mww@…]

I'd like to keep the sqlite3 and lib-tk files in the base installation so we do not have to disable them here and put them into the py25-tkinter.. ports. For the rest (the 95%): Damn good work - I'd say just go and commit them yourself!

[nox@…]

Commited in r29606! I'll try to do something about the sqlite3 and tkinter modules and IDLE.

There are still issues with python25 (rev 4), with regard to the (lack of) framework and this dylib. Please see ticket:11267, comment#11 .
