to that README file with some explanation. * Be more strict in the configure script: complain loudly when the user has specified invalid combinations of OSX-specific configure arguments. The error message refers to the Mac/README file for more information.

the Python distribution.

Mac-specific arguments to configure
|
||||
===================================
|
||||
|
||||
* ``--enable-framework``
|
||||
|
||||
If this argument is specified the build will create a Python.framework rather
|
||||
than a traditional Unix install. See the section
|
||||
_`Building and using a framework-based Python on Mac OS X` for more
|
||||
information on frameworks.
|
||||
|
||||
* ``--with-framework-name=NAME``
|
||||
|
||||
Specify the name for the python framework, defaults to ``Python``. This option
|
||||
is only valid when ``--enable-framework`` is specified.
|
||||
|
||||
* ``--enable-universalsdk[=PATH]``
|
||||
|
||||
Create a universal binary build of of Python. This can be used with both
|
||||
regular and framework builds.
|
||||
|
||||
The optional argument specifies with OSX SDK should be used to perform the
|
||||
build. This defaults to ``/Developer/SDKs/MacOSX.10.4u.sdk``, specify
|
||||
``/`` when building on a 10.5 system, especially when building 64-bit code.

||||

||||
See the section _`Building and using a universal binary of Python on Mac OS X`
|
||||
for more information.
|
||||
|
||||
* ``--with-univeral-archs=VALUE``
|
||||
|
||||
Specify the kind of universal binary that should be created. This option is
|
||||
only valid when ``--enable-universalsdk`` is specified.

installing Xcode.

The option ``--enable-universalsdk`` has an optional argument to specify an

2.1 Flavours of universal binaries
|
||||
..................................
|
||||
|
||||
It is possible to build a number of flavours of the universal binary build,
|
||||
the default is a 32-bit only binary (i386 and ppc). The flavour can be
|
||||
specified using the option ``--with-universal-archs=VALUE``. The following
|
||||
values are available:
|
||||
|
||||
* ``32-bit``: ``ppc``, ``i386``
|
||||
|
||||
* ``64-bit``: ``ppc64``, ``x86_64``

* ``all``: ``ppc``, ``ppc64``, ``i386``, ``x86_64``

* ``3-way``: ``ppc``, ``i386`` and ``x86_64``
|
||||
|
||||
* ``intel``: ``i386``, ``x86_64``
|
||||
|
||||
To build a universal binary that includes a 64-bit architecture you must build
|
||||
on a system running OSX 10.5 or later. The ``all`` flavour can only be build on

OSX 10.5.
