<H1>Building Mac Python from source</H1>
|
||||
<HR>
|
||||
This document explains how to build MacPython from source. This is necessary if
|
||||
you want to write extension modules for 68K Python, and currently also
|
||||
probably the easiest way to build PPC extension modules. Building Python
|
||||
is not something to be undertaken lightly, the process is not very streamlined
|
||||
so you need a reasonable working 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>

need is also included in the standard Python source distribution, but the organization

so if you don't need a certain package it suffices to just refrain from builing the

You need to make a minor organizational change to the Tcl/Tk

main Tcl folder.

<LI> Rename the <code>compat</code> folders to <code>(compat)</code>
|

in both the Tcl and Tk folders.
|
||||
|
||||
<LI> Fix the Tk and Tcl library project access paths: they refer to
|
||||
<code>MoreFiles 1.4.2</code>, change this to <code>MoreFiles 1.4.1</code>.
|
||||
Alternatively you could get the real MoreFiles 1.4.2, but there seem to be problems with
|
||||
this too (undefined references).
|
||||
<LI> In the Tcl folder, move <code>strncasecmp.c</code> and
|
||||
<code>tclErrno.h</code> from <code>(compat)</code> to the main Tcl
|
||||
folder.
|
||||
|
||||
<LI> Fix the Tk and Tcl library project header file: it is set to
|
||||
<code>MacHeaders.h</code> but should be set to <code>MW_TkHeader.h</code>
|
||||
and <code>MW_TclHeader.h</code> respectively.
|
||||
<LI> Fix <code>dnr.c</code> as provided by MetroWerks by inserting
|
||||
<pre><code> #pragma ANSI_strict off </code></pre> at the
|
||||
beginning. The tcl library is built with strict ANSI on, and this file
|
||||
uses C++ style comments.
|
||||
|
||||
<LI> You are <em>strongly</em> advised to make a fix to <code>tcl.h</code>. As distributed,
|
||||
tcl and tk assume that malloc calls always succeed and use the resulting pointer without
|
||||
checking for <code>NULL</code> values. Needless to say, this wreaks havoc on a Macintosh.
|
||||
Fortunately a checking malloc is included and easy to enable: look for the
|
||||
<code>#define</code>'s for ckalloc, ckfree and ckrealloc and replace them by the
|
||||
following code:
|
||||
<LI> If you want to build <code>SimpleTcl</code> and
|
||||
<code>SimpleTk</code> you will probably have to remove the references
|
||||
to <code>libmoto</code> from the project.
|
||||
|
||||
<LI> You are <EM>strongly</EM> advised to add a line
|
||||
<pre><code>
|
||||
# define ckalloc(x) Tcl_Ckalloc(x)
|
||||
# define ckfree(x) Tcl_Ckfree(x)
|
||||
# define ckrealloc(x,y) Tcl_Ckrealloc(x,y)
|
||||
#define USE_TCLALLOC 1
|
||||
</code></pre>
|
||||
With this fix, out-of-memory situations will still cause a hard abort of the python
|
||||
interpreter, but at least they will not crash your system.
|
||||
somewhere at the beginning of <code>MW_TclHeader.pch</code>.

|
||||
<LI> If you want to build <code>SimpleTcl</code> and <code>SimpleTk</code>
|
||||
to make sure that the distributions are working you should make the previous
|
||||
changes in those projects too. Moreover, you have to replace the MoreFiles
|

library reference by the correct one <code>MoreFiles 1.4.1:Libraries:MoreFiles.PPC</code>
|
||||
(or 68K).

<H2>Building Waste</H2>

You do not need to build the Waste libraries, as Python includes the

||||
source modules themselves. You have to make one modification,

though. In file <code>ICCFMGlue.c</code> in folder <code>Minimal IC
|

After creating the alias to <code>PythonCore</code> you should move <code>PythonPPC</code> to the main

folder (if you had python installed on your system before) and run the interpreter once to create the

correct preferences file. You should also make an alias to <code>PythonApplet</code> in the main Python

Next, you have to build the extension modules in the <code>PlugIns</code> folder. Open each project and

build it. After all the dynamically loaded modules are built you have to create a number of aliases: some

modules live together in a single dynamic library. Copy or move the <code>MkPluginAliases.py</code> script

from <code>Mac:scripts</code> to the main python folder and run it. <p>

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 this use only.

It may be possible to use the <code>PythonCore</code> shared library to embed Python in
|

another program, if your program can live with using GUSI for I/O. Use PythonCore in stead of
|

your C library (or, at the very least, link it before the normal C library). Let me know whether this

works.

add folders <code>Include</code>, <code>Mac:Include</code> and <code>Mac:mwerks</code> from the source
