Building a MacPython-OSX on top of Jaguar's /usr/bin/python
|
||
|
|
-----------------------------------------------------------
|
||
|
|
|
||
|
|
One way of getting MacPython functionality is to use the Python that Apple
|
||
|
|
supplies since MacOSX 10.2, and extend this with the missing bits.
|
||
|
|
|
||
|
|
(Another way is building a framework python, see Mac/OSX/README for
|
||
|
|
details on that).
|
||
|
|
|
||
|
|
Preparation
|
||
|
|
-----------
|
||
|
|
|
||
|
|
First of all you have to fix two things in the python distributed
|
||
|
|
by Apple. This paragraph is valid for 10.2 through 10.2.2, so if you
|
||
|
|
have a later version of Jaguar your mileage may vary.
|
||
|
|
|
||
|
|
1. /usr/lib/python2.2/config/Makefile has an erronuous reference to
|
||
|
|
building for intel processors. Edit the file with sudo, and change
|
||
|
|
the line
|
||
|
|
LDFLAGS= -arch i386 -arch ppc
|
||
|
|
to
|
||
|
|
LDFLAGS= -arch ppc
|
||
|
|
2. /usr/lib/python2.2/site-packages is not writeable except by root.
|
||
|
|
Make it writeable by administrators by doing
|
||
|
|
sudo chgrp admin /usr/lib/python2.2/site-packages
|
||
|
|
sudo chmod g+w /usr/lib/python2.2/site-packages
|
||
|
|
Alternatively you can do the make's below as superuser, but I
|
||
|
|
would advise against this.
|
||
|
|
|
||
|
|
Building
|
||
|
|
--------
|
||
|
|
|
||
|
|
Typing "make -f Makefile.jaguar" will build and install almost everything you need.
|
||
|
|
If you also want the "pythonw" unix program, which allows you to run GUI scripts from
|
||
|
|
a Terminal window, you should also do "sudo make -f Makefile.jaguar install_pythonw".
|
||
|
|
|
||
|
|
What do you get
|
||
|
|
---------------
|
||
|
|
|
||
|
|
After the make you will have a folder /Applications/MacPython-OSX that contains the
|
||
|
|
IDE and BuildApplet applications. Also, you will find a folder "python-additions" there
|
||
|
|
that contains the MacPython-specific additions to your installed Python. The only thing
|
||
|
|
that is installed outside the /Applications/MacPython-OSX folder is
|
||
|
|
/usr/lib/python2.2/site-packages/MacPython.pth, which is the magic file that will make
|
||
|
|
python find the new modules.
|
||
|
|
|
||
|
|
Uninstalling
|
||
|
|
------------
|
||
|
|
1. Remove /Applications/MacPython-OSX
|
||
|
|
2. Remove /usr/lib/python2.2/site-packages/MacPython.pth
|
||
|
|
|
||
|
|
How does it work?
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
Makefile.jaguar does most of the work by calling on Makefile (which is normally used
|
||
|
|
to build the Mac extensions for a framework-based python) after setting various
|
||
|
|
variables such that everything is built for /usr/bin/python. Some extension modules
|
||
|
|
(that are included in framework python 2.3a0, but missing from static python 2.2)
|
||
|
|
are built with setup.py. And some Carbon modules are built to replace their 2.2
|
||
|
|
versions, which lack required functionality. The stubs in Mac/Lib/Carbon know about
|
||
|
|
this overriding.
