BUILDING PYTHON 1.1 FOR THE MACINTOSH
|
|
*************************************
|
|
|
|
Python can be built on the Mac using either THINK C 6.0 (or 7.0) or
|
|
MPW 3.2. In the past it has been compiled with earlier versions of
|
|
these compilers, but no guarantees are made that the source is still
|
|
compatible with those versions. Likewise, new compiler versions may
|
|
effectively change the language accepted (or the library provided!)
|
|
and thus cause problems.
|
|
|
|
|
|
1. Using Think C 6.0
|
|
====================
|
|
|
|
1.1 The directory structure
|
|
---------------------------
|
|
|
|
I duplicate the UNIX directory structure from the distribution. The
|
|
subdirectories needed to compile are: Mac, Include, Parser, Python,
|
|
Objects, Modules. (Don't bother with Grammar and the parser
|
|
generator, nor with the Doc subdirectory.)
|
|
|
|
For running and testing, you also need Lib and its subdirectories test
|
|
and stdwin. You could also copy some things from the Demo/stdwin
|
|
directory (unfortunately most other demos are UNIX specific and even
|
|
many stdwin demos are).
|
|
|
|
Make sure there is no config.c file in the Modules subdirectory (if
|
|
you copy from a directory where you have done a UNIX build this might
|
|
occur). Also don't use the config.h generated on UNIX.
|
|
|
|
1.2 The project file
|
|
--------------------
|
|
|
|
I put all source files in one project, which I place in the parent
|
|
directory of the source directories.
|
|
|
|
1.2.1 Project type
|
|
|
|
(This is the Set Project Type... dialog in the Project menu.)
|
|
|
|
Set the creator to PYTH; turn on "far data"; leave "far code" and
|
|
"separate strs" unchecked (they just serve to bloat the application).
|
|
A partition size of 1000K should be enough to run the standard test
|
|
suite (which requires a lot of memory because it stress tests the
|
|
parser quite a bit) and most demos or medium-size applications. The
|
|
interpreter will do basic things in as little at 500K but this may
|
|
prevent parsing larger modules.
|
|
|
|
1.2.2 Compiler options
|
|
|
|
(This is the Options -> THINK C ... dialog in the Edit menu.)
|
|
|
|
- Start with Factory Settings.
|
|
|
|
- In the Prefix, remove #include <MacHeaders> and add
|
|
#define HAVE_CONFIG_H
|
|
|
|
- Choose any optimizer and debugger settings you like. - You
|
|
can choose 4-byte ints if you want. This requires that you
|
|
rebuild the ANSI and unix libraries with 4-bytes ints as well
|
|
(better make copies with names like ANSI 32 bit). With 4-byte
|
|
ints the interpreter is marginally bigger and somewhat (~10%)
|
|
slower, but Python programs can use strings and lists with
|
|
more than 32000 items (with 2-byte ints these can cause
|
|
crashes). The range of Python integers is not affected (these
|
|
are always represented as longs).
|
|
|
|
1.2.3 Files to add
|
|
|
|
(This is the Add Files... dialog in the Source menu.)
|
|
|
|
The following source files must be added to the project. I use a
|
|
separate segment for each begin letter -- this avoids segment
|
|
overflow, except for 'c', where you have to put either ceval.c or
|
|
compile.c in a separate segment. You could also group them by
|
|
subdirectory or function, but you may still have to split segments
|
|
arbitrarily because of the 32000 bytes restriction.
|
|
|
|
- From Mac: all .c files except fopenRF.c [[which shouldn't even
|
|
be there]].
|
|
|
|
- From Parser: acceler.c, grammar1.c, intrcheck.c,
|
|
myreadline.c, node.c, parser.c, parsetok.c, tokenizer.c.
|
|
|
|
- From Python: bltinmodule.c, ceval.c, cgensupport.c,
|
|
compile.c, errors.c, getopt.c, graminit.c, import.c,
|
|
marshal.c, modsupport.c, mystrtoul.c, pythonmain.c,
|
|
pythonrun.c, sigcheck.c, structmember.c, sysmodule.c,
|
|
traceback.c (i.e. all .c files except dup2.c, fmod.c,
|
|
frozenmain.c, getcwd.c, getmtime.c, memmove.c, sigcheck.c,
|
|
strerror.c, strtod.c, thread.c)
|
|
|
|
- From Objects: all .c files except xxobject.c.
|
|
|
|
- From Modules: all the modules listed in config.c (in the Mac
|
|
subdirectory) in the initializer for inittab[], before
|
|
"ADDMODULE MARKER 2". Also add md5c.c if you add md5module.c,
|
|
and regexpr.c if you add regexmodule.c. (You'll find
|
|
macmodule.c in the Mac subdirectory, so it should already have
|
|
been added in a previous step.) Note that for most modules,
|
|
the source file is called <name>module.c, but for a few long
|
|
module names it is just <module>.c. Don't add stdwinmodule.c
|
|
yet,
|
|
|
|
The following THINK C libraries must be added: from Standard
|
|
Libraries, ANSI and unix; from Mac Libraries, MacTraps. I put each
|
|
library in a separate segment. Also see my earlier remark on 4-byte
|
|
ints.
|
|
|
|
1.4 Adding STDWIN
|
|
-----------------
|
|
|
|
STDWIN is built in two separate projects: stdwin.pi contains the core
|
|
STDWIN implementation from Ports/mac, textedit.pi contains the files
|
|
from Packs/textedit. Use the same compiler options as for Python and
|
|
the same general source setup (in a sister directory of the toplevel
|
|
Python directory). Put all sources in the same segment. To
|
|
stdwin.pi, also add Tools/strdup.c and Gen/wtextbreak.c.
|
|
|
|
The two projects can now be added as libraries to the Python project.
|
|
You must also add stdwinmodule.c and add "#define USE_STDWIN" to the
|
|
Prefix in the compiler options dialog (this only affects macmain.c and
|
|
config.c).
|
|
|
|
Note that stdwinmodule.c contains an #include statement that
|
|
references "stdwin.h" by relative path name -- if the stdwin toplevel
|
|
directory is not a sibling of the python toplevel directory, you may
|
|
have to adjust the number of colons in the pathname.
|
|
|
|
1.5 Resources
|
|
-------------
|
|
|
|
Since I created them with ResEdit I have no text source of the
|
|
resources needed to give the application an icon etc... You can copy
|
|
the size, bundle, file reference and icon resources from the
|
|
distributed Python application with ResEdit. THINK C automatically
|
|
copies resources into the application file from a file
|
|
<projectname>.rsrc.
|
|
|
|
|
|
2. Using MPW 3.2
|
|
================
|
|
|
|
The subdirectory MPW contains a README.MPW file, a buildall script and
|
|
several Makefiles, kindly contributed by Richard Walker of Island
|
|
Software. Move these files to the corresponding locations relative to
|
|
the Python root directory (where Mac-Makefile should become Makefile
|
|
in the Mac subdirectory, etc.), and run the buildall script. The
|
|
README.MPW file contains more instructions and caveats (I've added
|
|
some remarks of my own at the end).
|
|
|
|
Some notes:
|
|
|
|
- The MPW and THINK C ports share all source files, including config.c
|
|
and config.h -- all differentiation is done based on #ifdef THINK_C
|
|
or #ifdef MPW (#ifdef macintosh is used for code that should be seen
|
|
by all Mac compilers).
|
|
|
|
- The dynload subdirectory contains an attempt to create dynamically
|
|
loadable modules from CODE segments. This was not very successful
|
|
due to the restrictions on CODE segments (no global variables, no
|
|
calls to external functions). Maybe Apple's new shared library
|
|
manager will be a better starting point.
|
|
|
|
- I haven't tried building STDWIN with MPW recently. There is MPW
|
|
specific code all over the STDWIN source but it is for a much older
|
|
version of the compiler and library.
