[PyKDE] Building SIP on MacOS 10.3.2

[Stephen Schaub]

I'm attempting to build SIP on Mac OS X 10.3.2 and am having difficulty. I
have successfully built Qt 3.3.1 on this machine and have tested some apps,
including the Qt designer. I have a fairly straightforward installation of
the OS X developer tools (no Fink stuff).

I downloaded SIP 4.0 rc2 and unpacked. I then ran configure.py and got the
following output:

--------------------------------------------------------------------------
[C10054:~/Documents/sip-4.0rc2] sschaub% python configure.py -l qt-mt
This is SIP 4.0rc2 for Python 2.3 on darwin.
The SIP code generator will be installed in
/System/Library/Frameworks/Python.framework/Versions/2.3/bin.
The SIP module will be installed in
/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/
site-packages.
The SIP header file will be installed in
/System/Library/Frameworks/Python.framework/Versions/2.3/include/
python2.3.
The default directory to install .sip files in is
/System/Library/Frameworks/Python.framework/Versions/2.3/share/sip.
Qt v3.3.1 free edition is being used.
The Qt header files are in /Developer/qt/include.
The qt-mt Qt library is in /Developer/qt/lib.
Qt's default platform/compiler configuration will be used.

So far, so good. I ran make, and got the following:
------------------------------------------------------------------------

.. several related error messages appeared ...
------------------------------------------------------------------------ 

A missing include file! I looked in
/System/Library/Frameworks/Python.framework/Versions/2.3
and did not find an include directory. Apparently the python
distribution included with Mac OS X 10.3 does not have include files.
So, I downloaded the python 2.3 source, created an include/python2.3
directory, and copied files from the python distribution's Include and
Mac/Include folders into it. Then, I ran make again:

------------------------------------------------------------------------

------------------------------------------------------------------------ 

It appears that the compile configuration is attempting to #include wchar.h,
which is not available on OS X. It seems I either have the wrong header
files, or somehow certain preprocessor symbols aren't being set correctly by
the Sip Makefile.

I did try this with the latest Sip snapshot, with the same results.

I teach a Unix Programming class and hope to give my students some
exposure to building cross-platform GUI apps with Python on both Linux
and Mac OS X. Qt and Python look like a great combination! I would
appreciate any suggestions to get it working.
