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.

I need to submit C/C++ code for a class. (It's not a programming
class. The choice of language is inertial. I think that it mostly
serves to distract students from the course subject.) I'm fairly
fluent with C but it hurts to think about writing in C when Python
is *so* much more appropriate for these operations.
I'd like to keep my sanity and satisfy the course requirements by
programming in Python and converting the code to C. It...

I mentioned earlier that I started using Pyrex because I'm taking a
computer vision course that requires all assignments to be submitted
as C(++). While I could write C it would hurt me to do so and
certainly distract me from the computer vision aspects. I like
using Python these days and Pyrex looked like a good solution.
(BTW, on the last assignment I saw several messages from someone
having difficulty with segfaults due to memory...

I just read "about Pyrex" at
http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/version/Doc/About.html
It seems that it is not compiled into machine code, as C would be, and
therefore it does not offer the only valid reason for using C, which is
for an increase in execution speed. The word "speed" does not appear on
the above web page.
Am I wrong about this? Perhaps I don't understand how Pyrex works.

I have recently started to use Pyrex and am amazed by it's useability.
Are there any alternatives to Pyrex?
One thing that I haven't figured out is how to embed pure C/C++ source code
into Pyrex. For example, if you have a bunch of C files that you want to
use together with some Python code snippets, how do you practically achieve
this using Pyrex? I have come to the conclusion that it is not possible
without some rewriting and...

I'm trying to move a function into pyrex for speed. The python side
needs to pass a list to the pyrex function. Do I need to convert to
array or something so pyrex can generate tight code? I'm not clear how
to do this.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
