How to build Python from a source distribution.
|
|
-----------------------------------------------
|
|
|
|
You will need a Python source distribution in tar form. So, the
|
|
first thing you need is a tar program for the mac. Suntar is
|
|
reasonable and can be found at the info-mac sites. Edit the
|
|
preferences to make it extract C sources with creator CWIE
|
|
and .py files as text files with creator Pyth, this will save
|
|
you work later.
|
|
|
|
You will also need CodeWarrior 8. If you have another development
|
|
environment you are on your own, basically.
|
|
|
|
You may also need the img distribution and the stdwin distribution.
|
|
If you don't want them you may have to edit some of the projects
|
|
to remove references to them.
|
|
|
|
When you've extracted everything you may have to unpack the
|
|
.hqx files in Mac:Resources and Mac:mwerks:Projects (but suntar
|
|
may have done this for you already).
|
|
|
|
You have to remove Modules:fmmodule.c, the SGI fm module, which has a
|
|
name conflict with the Mac Fmmodule.c.
|
|
|
|
Next, create your build directories. I use the following naming
|
|
convention:
|
|
build.macppc.shared PowerPC shared-library
|
|
build.mac68k.stand 68K non-shared
|
|
and there are also projects for ppc standalone and some others, they
|
|
may be useful at times. The project files expect the build directories
|
|
to be located right in the main python folder, if you put them elsewhere
|
|
you will have to edit the access paths.
|
|
|
|
Move MWCPythonCoreRuntime.µ, PythonCore.µ, PythonPPC.µ and
|
|
PythonApplet.µ (from the Mac:mwerks:projects folder) to
|
|
build.macppc.shared, move Python68K.µ to build.mac68k.stand.
|
|
|
|
Build the projects. For the PPC projects, keep the order given above.
|
|
Do *not* run the python interpreter yet. First, move the interpreter
|
|
to the main python folder. For PPC, also move PythonCore to the main
|
|
python folder.
|
|
|
|
Now try your python interpreter, this will create an initial
|
|
preferences file.
|
|
|
|
For 68K python you are now done.
|
|
|
|
For PPC Python, don't try complicated scripts yet, you first have to
|
|
create the dynamically loadable modules. Create a folder PlugIns (in
|
|
the toplevel python folder) and move all the projects that have
|
|
"module" or "modules" in their name there. Build these projects. This
|
|
will create a number of ".exp" files, edit these files to contain only
|
|
all the "init" modules, and build the projects again. This latter step
|
|
isn't really essential, so feel free to skip it.
|
|
|
|
The next step is to create aliases for the various modules that "live
|
|
together" in one shared library. For this, take MkPluginAliases.py and
|
|
MkPluginAliases.rsrc from the Mac:scripts folder and move or copy them
|
|
to the python home folder. Run the script from there.
|
|
|
|
If you haven't created all plugins you'll get some errors about files
|
|
not existing, don't worry. Don't forget to move the scripts back.
|
|
|
|
Next, make an alias of PythonCore (also named PythonCore) and put it
|
|
in System Folder:Extensions. This will ensure that you can run python
|
|
anywhere, not just from the folder where PythonCore lives.
|
|
|
|
Most of your environment is now setup. You can try it by running
|
|
EditPythonPrefs.py (in Mac:scripts), it should now work from there.
|
|
|
|
Lastly, you should setup some stuff needed for applet creation. First,
|
|
you should put PythonApplet (or an alias to it) in the python home
|
|
folder. Next, you should turn mkapplet.py (from mac:scripts) into an
|
|
applet itself: double-click it and give it itself as input in the
|
|
input file dialog.
|
|
|
|
Now that you have created mkapplet you can use this as a droplet:
|
|
drag-and-drop python sources onto it (EditPythonPrefs.py and
|
|
RunLibScript.py come to mind) and the applets will be created.
