This document explains how to build MacPython from source. This is
|
|
|
|
necessary if you want to write extension modules for 68K Python, and
|
1999-02-03 13:09:27 +00:00
|
|
|
is also necessary if you want to make modifications to the Python core.
|
|
|
|
Building Python is not something to be undertaken lightly,
|
|
|
|
you need a reasonable working
|
1996-08-06 16:16:20 +00:00
|
|
|
knowledge of the CodeWarrior development environment, a good net
|
|
|
|
connection and probably quite some time too. <p>

The information density in this file is high, so you should probably
|
|
|
|
print it and read it at your leasure. Most things are explained only
|
|
|
|
once (and probably in the wrong place:-). <p>

obtain one from <A

or from the companion webpage at <A HREF="http://www.cwi.nl/~jack/macpython.html">
|
|
|
|
http://www.cwi.nl/~jack/macpython.html</A> (which has up-to-date links to the other
|
|
|
|
packages needed too)
|
1996-08-06 16:16:20 +00:00

|
and possibly also from the standard <A
|
|
|
|
HREF="ftp://ftp.python.org/pub/python/mac">python.org ftp
|
|
|
|
site</A>. Everything you need is also included in the standard Python
|
|
|
|
source distribution, but the organization is different. Look in
|
|
|
|
directory <code>Mac/mwerks/projects</code> for the project files and
|
1999-02-03 13:09:27 +00:00

related stuff. <BR>

If you are a <a href="http://www.python.org/psa">PSA</a> member, an alternative
|
|
|
|
is to check the sources straight out of the CVS repository,
|
|
|
|
see below. Most of the packages mentioned here are also available through CVS.

<LI> You need MetroWerks CodeWarrior. The current distribution has
|
1999-02-03 13:09:27 +00:00
|
|
|
been built with CodeWarrior Pro 4. Ordering information is

1996-08-06 16:16:20 +00:00

available on the <A HREF="http://www.metrowerks.com/">MetroWerks

|
|
|
|
probably impossible without major surgery.

1997-08-27 14:08:22 +00:00

At the moment Python is built with a slightly modified version of GUSI,
|
1999-02-10 23:08:24 +00:00
|
|
|
these modifications are available in folder <code>Python:Mac:GUSI-mods</code>. <br>

|
|
|
|
|
|
|
The modified GUSI is also in the MacPython cvs source repository, in the
|
|
|
|
directory <code>lib-src/CWGUSI</code>. However, some files contain slashes in
|
|
|
|
their names, something CVS seriously frowns upon, and each slash has been
|
|
|
|
replaced by <code>"_s_"</code>. There is a script
|
|
|
|
<code>Mac:scripts:fixgusidir.py</code> which you should run after checking CWGUSI

number of extra packages. To use the project files as-is you have to

1996-08-23 15:44:18 +00:00

download these packages too. PPC and CFM68K Python have all such modules as

(which includes libtiff) is generally available on Internet ftp
|
|

|
servers. For Python pbmplus, an older incarnation of netpbm, is
|
|
|
|
functionally identical to netpbm, since Python only uses the library
|
|
|
|
and not the complete applications. A distribution with correct
|
1997-05-07 15:43:38 +00:00

projects and library source only is available from, you guessed it, Jack's Mac software

at <code>lib-src/netpbm</code>, etc. The only gotcha is that libtiff lives in

|
<code>lib-src/netpbm/libtiff</code>, for historical reasons.

If your setup of the libraries is exactly the same as mine (which is
|
|
|
|
not very likely, unless you happen to work from the same CVS
|
|
|
|
repository) you can use the project <code>buildlibs.prj</code> in the
|
1999-02-03 13:09:27 +00:00
|
|
|
<code>:Mac:build.mac</code> folder to build all needed libraries in one
|
1998-08-27 13:39:01 +00:00
|
|
|
fell swoop, otherwise you will have to build the libraries one by
|
|
|
|
one. <p>
|
|
|
|
|
1997-05-07 15:43:38 +00:00
|
|
|
First build GUSI. If you didn't get the python-specific GUSI you have to
|
|
|
|
move the files from the "CWGUSI-mods" to the right
|
1997-08-27 14:08:22 +00:00
|
|
|
place in the CWGUSI distribution folder. Build the MSL version for your
|
|
|
|
platform (ppc, 68k, cfm68k). <p>

1998-02-25 15:40:35 +00:00

and<code>libtiff</code> you build all projects. Usually the projects are in "mac"
|
1997-05-07 15:43:38 +00:00
|
|
|
subfolders, sometimes they are in the main folder. Tcl/tk is a special
|
1996-08-23 15:44:18 +00:00
|
|
|
case, see below. Of course, if you are only interested in one of
|
|
|
|
static 68K, CFM68K or PPC you can skip building the other libraries.

1997-08-27 14:08:22 +00:00

|
You need to make some minor changes to the Tcl/Tk 8.0
|
|
|
|
distribution. You should make the CW Pro projects (in the mac subfolders).

<LI> There are no cfm68k targets. You make these by copying the 68k targets,
|
|
|

setting the "68k target" to "cfm68k library" and changing the output filename,

|

and changing the prefix

header filename in the C/C++ settings panel to "MW_???HeaderCFM68K".

|
1996-12-23 17:29:51 +00:00
|
|
|
|
|
|
|
<LI> Note that if you use a different release of Tcl and Tk than the ones
|
|
|
|
I have used you may have to adapt the Python <code>tkresources.rsrc</code> file.
|
|
|
|
This is easiest done by building <code>SimpleTk</code> and copying the TEXT, ICON
|
|
|
|
and CRSR resources from it to <code>tkresources.rsrc</code>. This allows
|
|
|
|
the <code>_tkinter</code> module to work without an installed Tk/Tcl on your
|
|
|
|
machine.

SimpleTcl (test it by typing <code>ls -l</code> in the window you get)
|

then the Tk library, then SimpleTk (which can again be tested with

|
<code>ls -l</code>). If this all worked you are all set to try

building Python.

the <code>img</code>, <code>Imaging</code> and <code>Numeric</code> extensions
|
|
|
|
in this distribution. Nowadays, the extensions are all built in their own
|
|
|
|
folders (unlike in older distributions, where img was incorporated in the main

build procedure).

modules (for the 68K interpreter), building non-GUSI interpreters and

If you have all the optional libraries mentioned <A
|
1999-02-03 13:09:27 +00:00
|
|
|
HREF="#optional">above</A> loaded building Python for 68K macs is a
|
|
|
|
breeze: in the Mac:Build folder you build the libraries with buildlibs.prj
|
|
|
|
and then the interpreter with PythonStandalone.prj. <p>
|
|
|
|
|
|
|
|
If you were previously running another copy of this Python release,
|
|
|
|
from a binary installer for instance, you should
|
|
|
|
first remove the <code>Python XXX preferences</code> file from your
|
|
|
|
preference folder. Next, run the interpreter, in the toplevel folder. This will
|
1996-08-06 16:16:20 +00:00
|
|
|
create a correct initial preferences file. You are now all set, and
|
|
|
|
your tree should be completely compatible with a binary-only
|
|
|
|
distribution. Read the release notes
|
|
|
|
(<code>Relnotes-somethingorother</code>) and
|
1999-02-03 13:09:27 +00:00
|
|
|
<code>ReadMe</code> in the <code>Mac</code> folder. <p>
|
|
|
|
|
|
|
|
If something goes wrong you may end up with a garbled preferences file. Removing
|
|
|
|
it from the system folder and running Python once again will re-create it.

|

1999-02-03 13:09:27 +00:00
|
|
|
First you optionally build the external libraries with buildlibs.prj. Next,
|
|
|
|
the projects for
|
|
|
|
interpreter, core library and applet skeleton are all linked together, so
|
1997-08-27 14:08:22 +00:00
|
|
|
building the fat targets in <code>Python.prj</code> and
|
|
|
|
<code>PythonApplet.prj</code> will result in everything being built. The
|
|
|
|
resulting applications and fat shared library are deposited in the main
|
1999-02-03 13:09:27 +00:00
|
|
|
Python folder. Finally, you build all the plugins with the plugins.prj project.
|
|
|
|
|
|
|
|
For completeness sake here is a breakdown of the projects:

|
1996-08-06 16:16:20 +00:00
|
|
|
<DD> The shared library that contains the bulk of the interpreter and
|
|
|
|
its resources. It is a good idea to immedeately put an alias to this
|
|
|
|
shared library in the <code>Extensions</code> folder of your system
|
|
|
|
folder. Do exactly that: put an <em>alias</em> there, copying or
|
1997-08-27 14:08:22 +00:00
|
|
|
moving the file will cause you grief later if you rebuild the library and
|
1999-02-03 13:09:27 +00:00
|
|
|
forget to copy it to the extensions folder again. The InstallPython applet
|
|
|
|
will also do this, along with creating the plugin aliases.
|
1996-08-05 15:34:45 +00:00
|

1997-08-27 14:08:22 +00:00
|
|
|
<DT> Python
|
1996-08-06 16:16:20 +00:00
|
|
|
<DD> The interpreter. This is basically a routine to call out to the
|
1997-08-27 14:08:22 +00:00
|
|
|
shared library. <p>
|
1996-08-05 15:34:45 +00:00

|
|
|
<DT> PythonAppletPPC
|
1996-08-06 16:16:20 +00:00
|
|
|
<DD> The applet skeleton application. Very similar to
|
|
|
|
<code>PythonPPC</code>, but it calls to a different entrypoint in the
|
|
|
|
core library. The <code>mkapplet</code> script will copy this complete
|
|
|
|
file, and add a <code>'PYC '</code> with the module to generate an
|
|
|
|
applet. <p>

1996-08-05 15:34:45 +00:00

1999-02-03 13:09:27 +00:00
|
|
|
<DT> Plugin projects
|
1999-02-10 23:08:24 +00:00
|
|
|
<DD> Each plugin module has a separate project. The <code>Plugins.prj</code>
|
|
|
|
project tries to build them all, but is known to be flakey under CW Pro 4.

|
|
|
|
1997-08-27 14:08:22 +00:00
|
|
|
After creating the alias to <code>PythonCore</code> you remove any old
|
1996-10-22 15:27:56 +00:00
|
|
|
<code>Python XXX Preferences</code> file from the <code>Preferences</code> folder
|
|
|
|
(if you had python installed on your system before) and run the interpreter once
|
1997-08-27 14:08:22 +00:00
|
|
|
to create the correct preferences file. <p>
|
1996-08-06 16:16:20 +00:00
|
|
|
|
1999-02-03 13:09:27 +00:00
|
|
|
Next, you have to build the extension modules.
|
|
|
|
The <code>PlugIns.ppc</code> project has all the
|
1999-02-10 23:08:24 +00:00
|
|
|
other projects as subprojects and builds everything (but see the gotcha above).
|
|
|
|
<p>
|
1996-08-06 16:16:20 +00:00
|
|
|
|
|
|
|
Finally, you must build the standard applets:
|
1997-08-27 14:08:22 +00:00
|
|
|
<code>EditPythonPrefs</code>, <code>BuildApplet</code>, etc. This is
|
1996-08-06 16:16:20 +00:00
|
|
|
easiest done with the <code>fullbuild</code> script from
|
1997-08-27 14:08:22 +00:00
|
|
|
<code>Mac:scripts</code>. <p>

|
<BLOCKQUOTE>
|
1996-08-06 16:16:20 +00:00
|
|
|
Actually, the <code>fullbuild</code> script can be used to build
|
|
|
|
everything, but you need a fully-functional interpreter before you can
|
|
|
|
use it (and one that isn't rebuilt in the process: you cannot rebuild
|
|
|
|
a running program). You could copy the 68K interpreter to a different
|
|
|
|
place and use that to run fullbuild, or use the standalone PPC python
|
|
|
|
for this. I tend to keep a standalone interpreter in a safe place for
|
1997-05-29 14:57:07 +00:00
|
|
|
this use only. <p>

You are all set now, and should read the release notes and
|
1997-08-27 14:08:22 +00:00
|
|

<code>ReadMe</code> file from the <code>Mac</code> folder.

<H2>Rebuilding <code>.exp</code> files for PPC and CFM68K</H2>
|
|
|
|
|
|
|
|
Occasionally it may be necessary to rebuild your PythonCore <code>.exp</code>
|
|
|
|
file, a file that controls which symbols are exported by your PythonCore
|
|
|
|
shared library. Rebuild it if you get unexpected undefined symbols when you
|
|
|
|
are building a plugin module. <p>
|
|
|
|
|
|
|
|
Rebuilding the .exp file is done by first removing the file and removing the
|
|
|
|
reference to it in the project (in the "config" section). Next, build PythonCore.
|
|
|
|
This will create a new .exp file. Edit this file to remove the references to
|
|
|
|
the symbols <code>__initialize</code>, <code>__terminate</code>, <code>setjmp</code>,
|
1997-05-07 15:43:38 +00:00
|
|
|
<code>longjmp</code>, <code>main</code> and (for PPC) <code>__ptmf_null</code> or (for
|
|
|
|
CFM68K) <code>__start</code> and <code>dummy_init_routine</code>.
|
|
|
|
Next, add the .exp file to the project
|
1996-08-23 15:44:18 +00:00
|
|
|
again and rebuild PythonCore. <p>
|
|
|
|
|
|
|
|
This rather convoluted procedure is needed to ensure that plugin modules don't
|
|
|
|
accidentally link with those entrypoints from PythonCore, which will not work because
|
|
|
|
those routines have to be in the same code fragment as they are used from.

<H2>Using the CVS source archive</H2>
|
|
|
|
|
|
|
|
It is possible to access the Python sources through remote CVS if you are
|
|
|
|
a PSA member. The advantage of this is that you get the very latest sources,
|
|
|
|
so any bug fixed or new features will be immedeately available. This is also
|
|
|
|
the disadvantage, of course: as this is the same tree as is used for development it
|
|
|
|
may sometimes be a little less stable. <p>
|
|
|
|
|
|
|
|
The CVS client of choice is Alexandre Parenteau's MacCVS. It can be
|
|
|
|
obtained through the <a href="http://www.cyclic.com">Cyclic CVS homepage</a>. MacCVS
|
|
|
|
uses Internet Config to set file types correctly based on the filename extension. In
|
|
|
|
the maccvs preferences you should also set (in the "binary files" section)
|
|
|
|
"use mac encoding: applesingle" and (in the "text files" section) "use ISO latin 1
|
|
|
|
conversion". <p>
|
|
|
|
|
|
|
|
The machine-independent Python sources are checked out from the main Python
|
|
|
|
CVS archive, see the <a href="http://www.python.org/psa">PSA homepage</a> for
|
|
|
|
details. <p>
|
|
|
|
|
|
|
|
Next, within the toplevel Python folder, you check out the mac-specific sources
|
|
|
|
in a Mac folder. The CVS path to use can be found at the
|
|
|
|
<a href="http://www.cwi.nl/~jack/macpython.html">MacPython homepage</a>. Finally,
|
|
|
|
you check out the external libraries needed in the parent of the Python folder. The
|
|
|
|
CVS path for these libraries is also mentioned at the MacPython homepage. <p>
|
|
|
|
|
|
|
|
Neither of the pages mentioned above contains the passwords for the CVS sites,
|
|
|
|
for obvious reasons, but they do contain instructions on how to obtain the passwords. <p>

|
<LI> It may be possible to use the <code>PythonCore</code> shared
|
|
|
|
library to embed Python in another program, if your program can live
|
1997-05-07 15:43:38 +00:00
|
|
|
with using GUSI for I/O. Use PythonCore in stead of your MSL C library
|
1996-08-06 16:16:20 +00:00
|
|
|
(or, at the very least, link it before the normal C library). Let me
|
|
|
|
know whether this works.

|
<LI> It is possible to build PPC extension modules without building a

1999-02-03 13:09:27 +00:00

complete Python. The binary distribution installer can optionally install
|
|
|

<LI> The Python shared library architecture is a variant of the architecture
|
|
|
|
described as "application with shared libraries and dropins" in the MetroWerks
|
|
|
|
"Targeting MacOS" documentation. The Python Application and applet-template use
|
1997-05-07 15:43:38 +00:00
|
|
|
the <code>MSL AppRuntime.Lib</code> runtime library (with properly set CFM
|
|
|
|
initialization and termination routines). PythonCore uses <code>MSL Runtime.Lib</code>,
|
|
|
|
which is really intended for standalone programs but which we fool into working by
|
|
|
|
providing a dummy main program.
|
1996-08-23 15:44:18 +00:00
|
|
|
It is linked statically into PythonCore (and exported to the applications and plugins)
|
|
|
|
so we do not have to distribute yet another shared library. Plugin modules use
|
1997-05-07 15:43:38 +00:00
|
|
|
<code>MSL ShlibRuntime.Lib</code> (not the dropin runtime: modules are never unloaded)
|
|
|
|
and obtain the rest from PythonCore. PythonCore uses a
|
1996-08-23 15:44:18 +00:00
|
|
|
non-standard initialization entry point, <code>__initialize_with_resources</code>, to
|
1997-05-07 15:43:38 +00:00
|
|
|
be able to obtain resources from the library file later on. Plugins can do the same
|
|
|
|
(_tkinter does) or use the standard <code>__initialize</code> entry point.
