Welcome to the "PC" subdirectory of the Python distribution!
|
|
************************************************************
|
|
|
|
(NOTE: the project files for MS VC++ 5.x are now in the PCbuild
|
|
directory. See the file readme.txt there for instructions.)
|
|
|
|
This "PC" subdirectory contains complete project files to make
|
|
several PC ports of Python, as well as all the PC-specific
|
|
Python source files. It should be located in the root of the
|
|
Python distribution, and there should be directories "Modules",
|
|
"Objects", "Python", etc. in the parent directory of this "PC"
|
|
subdirectory. Be sure to read the documentation in the Python
|
|
distribution.
|
|
|
|
Python requires library files such as string.py to be available in
|
|
one or more library directories. The search path of libraries is
|
|
set up when Python starts. To see the current Python library search
|
|
path, start Python and enter "import sys" and "print sys.path".
|
|
|
|
All PC ports use this scheme to try to set up a module search path:
|
|
|
|
1) The script location; the current directory without script.
|
|
2) The PYTHONPATH variable, if set.
|
|
3) For Win32 platforms (NT/95), paths specified in the Registry.
|
|
4) Default directories lib, lib/win, lib/test, lib/tkinter;
|
|
these are searched relative to the environment variable
|
|
PYTHONHOME, if set, or relative to the executable and its
|
|
ancestors, if a landmark file (Lib/string.py) is found ,
|
|
or the current directory (not useful).
|
|
5) The directory containing the executable.
|
|
|
|
The best installation strategy is to put the Python executable (and
|
|
DLL, for Win32 platforms) in some convenient directory such as
|
|
C:/python, and copy all library files and subdirectories (using XCOPY)
|
|
to C:/python/lib. Then you don't need to set PYTHONPATH. Otherwise,
|
|
set the environment variable PYTHONPATH to your Python search path.
|
|
For example,
|
|
set PYTHONPATH=.;d:\python\lib;d:\python\lib\win;d:\python\lib\dos-8x3
|
|
|
|
There are several add-in modules to build Python programs which use
|
|
the native Windows operating environment. The ports here just make
|
|
"QuickWin" and DOS Python versions which support a character-mode
|
|
(console) environment. Look in www.python.org for Tkinter, PythonWin,
|
|
WPY and wxPython.
|
|
|
|
To make a Python port, start the Integrated Development Environment
|
|
(IDE) of your compiler, and read in the native "project file"
|
|
(or makefile) provided. This will enable you to change any source
|
|
files or build settings so you can make custom builds.
|
|
|
|
config.h An important configuration file specific to PC's.
|
|
|
|
config.c The list of C modules to include in the Python PC
|
|
version. Manually edit this file to add or
|
|
remove Python modules.
|
|
|
|
testpy.py A Python test program. Run this to test your
|
|
Python port. It should produce copious output,
|
|
ending in a report on how many tests were OK, how many
|
|
failed, and how many were skipped. Don't worry about
|
|
skipped tests (these test unavailable optional features).
|
|
|
|
src A subdirectory used only for VC++ version 1.5 Python
|
|
source files. See below. The other compilers do not
|
|
use it. They reference the actual distribution
|
|
directories instead.
|
|
|
|
|
|
Microsoft Visual C++ Version 4.x (32-bit Windows)
|
|
=================================================
|
|
|
|
(For historic reasons this uses the filename "vc40"; it has been tested
|
|
most recently with VC 4.2. See ../PCbuild for VC 5.x.)
|
|
|
|
NOTE: VC 4.2 support is eroding, as I no longer have a VC 4.2
|
|
installation. Some newer files need to be added to the project.
|
|
|
|
The distributed Makefile is vc40.mak. This file is distributed with
|
|
CRLF line separators, otherwise Developer Studio won't like it. It
|
|
will NOT work from this PC directory. To use it, first copy it to the
|
|
Python distribution directory, e.g. with this command:
|
|
copy vc40.mak ..
|
|
To convert the Makefile into a project file, start Developer Studio,
|
|
choose Open Workspace, change the file name pattern to *.mak, find and
|
|
select the file vc40.mak, and click OK. Developer Studio will create
|
|
additional project files vc40.ncb and vc40.mdp when you use the
|
|
project. The project contains six targets, which should be built in
|
|
this order:
|
|
|
|
python15 The Python core as a DLL, named python15.dll.
|
|
|
|
python The Python main program, named python.exe. This should
|
|
work as a console program under Windows 95 or NT, as well
|
|
as under Windows 3.1(1) when using win32s. It uses
|
|
python15.dll.
|
|
|
|
_tkinter The optional _tkinter extension, _tkinter.dll; see below.
|
|
|
|
All end products of the compilation are placed in the subdirectory
|
|
vc40 (which Developer Studio creates); object files are placed in
|
|
vc40/tmp. There are no separate Release and Debug project variants.
|
|
Note that the python and _tkinter projects require that the
|
|
python15.lib file exists in the vc40 subdirectory before they can be
|
|
built.
|
|
|
|
*** How to build the _tkinter extension ***
|
|
|
|
This assumes that you have installed the Tcl/Tk binary distribution for
|
|
Windows 95/NT with version numbers 7.5p1/4.1p1, in the default
|
|
installation location (C:\tcl). (Ftp to ftp.sunlabs.com in /pub/tcl,
|
|
file win41p1.exe.) You must also fetch and unpack the zip file
|
|
vclibs41.zip which contains the files tcl75.lib and tk41.lib, and place
|
|
those files in the PC subdirectory. In order to use _tkinter, the
|
|
Tkinter.py module must be on PYTHONPATH. It is found in the
|
|
Lib\tkinter subdirectory.
|
|
|
|
|
|
Additional files and subdirectories for 32-bit Windows
|
|
======================================================
|
|
|
|
python_nt.def Exports definition file for python15.dll.
|
|
|
|
python_nt.rc Resource compiler input for python15.dll.
|
|
|
|
dl_nt.c, import_nt.c
|
|
Additional sources used for 32-bit Windows features.
|
|
|
|
getpathp.c Default sys.path calculations (for all PC platforms).
|
|
|
|
dllbase_nt.txt A (manually maintained) list of base addresses for
|
|
various DLLs, to avoid run-time relocation.
|
|
|
|
_tkinter.def The export definitions file for _tkinter.dll.
|
|
(No longer needed; the /export:init_tkinter takes care
|
|
of this.)
|
|
|
|
make_nt.in Include file for nmake-based builds (unsupported).
|
|
|
|
example_nt A subdirectory showing how to build an extension as a
|
|
DLL.
|
|
|
|
|
|
Microsoft Visual C++ Version 1.5 (16-bit Windows)
|
|
=================================================
|
|
|
|
Since VC++1.5 does not handle long file names, it is necessary
|
|
to run the "makesrc.exe" program in this directory to copy
|
|
Python files from the distribution to the directory "src"
|
|
with shortened names. Included file names are shortened too.
|
|
Do this before you attempt to build Python.
|
|
|
|
The "makesrc.exe" program is a native NT program, and you must
|
|
have NT, Windows 95 or Win32s to run it. Otherwise you will need
|
|
to copy distribution files to src yourself.
|
|
|
|
The makefiles are named *.mak and are located in directories
|
|
starting with "vc15_". NOTE: When dependencies are scanned
|
|
VC++ will create dependencies for directories which are not
|
|
used because it fails to evaluate "#define" properly. You
|
|
must manaully edit makefiles (*.mak) to remove references to
|
|
"sys/" and other bad directories.
|
|
|
|
vc15_lib A static Python library. Create this first because is
|
|
is required for vc15_w31.
|
|
|
|
vc15_w31 A Windows 3.1x Python QuickWin (console-mode)
|
|
Python including sockets. Requires vc15_lib.
|
|
|
|
|
|
Watcom C++ Version 10.6
|
|
=======================
|
|
|
|
The project file for the Watcom compiler is ./python.wpj.
|
|
It will build Watcom versions in the directories wat_*.
|
|
|
|
wat_dos A 32-bit extended DOS Python (console-mode) using the
|
|
dos4gw DOS extender. Sockets are not included.
|
|
|
|
wat_os2 A 32-bit OS/2 Python (console-mode).
|
|
Sockets are not included.
|
|
|
|
|
|
