Installation problem CBuilder 5.0

Hi all!

I have been running Python 1.5 for some time with CBuilder 5.0,
Update 1, under Windows XP (Professional Version 2002, Service Pack
2). I am trying to update to Python 2.1 or later.

I have downloaded the PythonForDelphi and Python 2.1.3, installed
them and can`t get my project or the demos to compile.

My projects that use math.h, the demo18 and demo20 projects get an
error during compilation, "[C++ Error] math.h(324): E2316 `abs` is
not a member of `std`".

The demo19 project gets an error during startup "raised exception
class EDLLImportError with message `Error 127: could not map symbol
Py_UnicodeFlag.`"

I`ve run implib on py21.lib and python21.dll. I`ve installed the b5
packages and doublechecked my paths.

Can anyone help?

Thanks, Irene

Which version did you get? Did you download it from http://mmm-experts.com?

Ok. But why don`t you go directly to 2.3 or 2.4?

Don`t know C++ well, but maybe this is a problem related to namespaces?

This error was raised by P4D when trying to import the Python APIs.
Apparently trying to import Py_UnicodeFlag with version 2.1.3 is wrong.
So, in the source code, try to replace the following code:
{$IFDEF PYTHON20_OR_HIGHER}
Py_UnicodeFlag: PInt;
{$ENDIF}

With
{$IFDEF PYTHON22_OR_HIGHER}
Py_UnicodeFlag: PInt;
{$ENDIF}

Repeat it for each instance of Py_UnicodeFlag.
If you get another problem, try to insert conditional compilation symbols.

Note that you should not have these problems with Python 2.3 or later...

Hope that helps,

Morgan

Your comment implies that PythonForDelphi will work with Python 2.4.

Is that true? When I try to install PFD it doesn`t see Python 2.4?

Of course it does! Why would I lie ;-)

As I already said, I can`t update my former web page, and all the P4D
related activity as been moved to my web site http://mmm-experts.com/

You can also, access the version history from the web site and look at
the latest changes...

Note that there will be interesting new changes very soon...

Bye,

Morgan
