- 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.
