Pyrex problem - Py_NoneStruct

[Gary Stephenson]

I'm getting a clean generate, compile and link from my .pyx script, but when
I attempt to run the resultant .exe, I get:

"The procedure entry point Py_NoneStruct could not be located in the
dynamic link library python23.dll"

Can anybody provide me with a clue here? I've already cut down my script to
remove all references to None, Py_None, NULLs, etc, but to no avail. fwiw
I'm using latest Pyrex and ActiveState build 232.

many tias,

gary

Hmm, what resultant .exe? Are you using py2exe or similar, or is
there a feature of Pyrex I haven't noticed? I've always ended up with
a .so / .DLL.

"The procedure entry point Py_NoneStruct could not be located in the

Had this before, but forget what the problem is.

Try posting some Pyrex code (the pyrex list is probably a better place
than here).

Hi John,

a .so / .DLL.

Err, yes ... I have used Pyrex before (successfully) using distutils to
produce a .DLL. In this case, however, I am effectively attempting to embed
Python within another language (Xbase++), so I am compiling the pyrex
generated .c file using MSVC6 into an ..obj file and linking that into my
Xbase++ app. It would appear that my problems arise from incorrect switches
to cl.exe. fwiw, the switches I"m using are: /c /Zl /Tc

I've searched high and low for some guidance on what the correct switches
might be, but alas to no avail thus far. :-(

I have attempted to post this message along with the .pyx file to the pyrex
list, but it would appear there is something wrong with my subscription as
I have received neither my own message not anybody else's since subscribing
:-(

cheers,

The following is a somewhat cut down version of my .pyx file whichl produces
the error:
