+IBM VisualAge C/C++ for OS/2

+============================

+

+To build Python for OS/2, change into ./os2vacpp and issue an

+'NMAKE' command.  This will build a PyCore15.dll containing the

+set of Python modules listed in config.c and a small Python.exe

+to start the interpreter.

+

+During the build process you will see a couple of harmless warnings:

+

+  From the C Compiler, "No function prototype given for XXX", which

+  comes from the use of K&R parameters within Python for portability.

+

+  From the ILIB librarian, "Module Not Found (XXX)", which comes

+  from its attempt to perform the (-+) operation, which removes and

+  then adds a .OBJ to the library.  The first time a build is done,

+  it obviously cannot remove what is not yet built.

+

+This build includes support for most Python functionality as well

+as TCP/IP sockets.  It omits the Posix ability to 'fork' a process

+but supports threads using OS/2 native capabilities.  I have tried

+to support everything possible, even popen() to run a child process

+and communicate with it via a pipe.

+

+With respect to the environment variables for Python, I use the

+following setup:

+

+    Set PYTHONHOME=E:\Tau\Projects\Python

+    Set PYTHONPATH=.;E:\Tau\Projects\Python\Lib; \

+                     E:\Tau\Projects\Python\Lib\Plat-OS2

+

+If you have questions or problems specifically with the VAC++ port

+of Python, please contact me at:

+

+    Jeff Rush <jrush@summit-research.com>.

+

+I support no other platform but OS/2 (and eventually AmigaDOS).
